Which fits your Power Automate renewal: Power Automate or self-hosted n8n
Power Automate fits when your flows live almost entirely inside Microsoft 365 and you already pay for the licensing that covers them. If your renewal is driven by per-user or per-bot pricing but your automations depend on SharePoint, Teams, Outlook and Dataverse, the built-in connector depth is the main reason to stay. Self-hosted n8n fits when most of your flows cross many third-party systems, when the cost of running flows per user is hard to justify, or when the runtime must sit inside your own network. The decision turns on four questions: how deep your Microsoft 365 connector dependencies run, whether you need desktop RPA, where the data must physically run, and who will operate the platform after go-live.
Start with an inventory of your flows, grouped by the connectors they call and the environment they run in. Flows that rely on Microsoft 365 services, Dataverse tables or on-premises data gateway connections need a per-flow check in n8n, because you will rebuild those connections rather than copy them. Flows that only call web APIs and databases are the strongest candidates to move. Check whether any of your automations drive legacy Windows applications through keyboard and mouse actions. n8n does not provide desktop RPA, so those flows need a separate plan. For n8n's licensing, confirm with n8n which edition covers your use: the Community edition is free to self-host, while SSO, Git-based environments and log streaming sit in the Business and Enterprise plans, as described on n8n's pricing page.
Which option fits which scenario
This table matches common Power Automate scenarios with the option that usually fits better, and the condition that makes the recommendation hold. Read each row against your own flow inventory, since a single estate often needs both tools for different flows.
| Scenario | Better fit | Why and under what condition |
|---|---|---|
| Flows mostly built on Microsoft 365 and Dataverse | Stay on Power Automate | Native connectors for Outlook, SharePoint, Teams and Dataverse are the deepest option. Consider n8n only if you accept building and maintaining those integrations yourself. |
| Flows that call internal APIs or databases behind the firewall | Self-hosted n8n | Running n8n inside your network lets flows reach internal services without an on-premises data gateway in the middle. Confirm that each target system has an API or a supported node your team can maintain. |
| Desktop RPA on legacy Windows apps with no API | Neither, pending a separate RPA decision | n8n does not provide desktop automation. Keep desktop flows where they are or plan a Robot Framework evaluation, and confirm the bot machines you would need to run. |
| Business makers building their own flows with little IT support | Power Automate or Activepieces | Power Automate suits makers already inside Microsoft 365. n8n assumes some technical comfort with its canvas and code nodes, so confirm your makers' skills before moving them. |
| Regulated teams that must keep runtime inside their network | Self-hosted n8n | A self-hosted runtime keeps workflow execution and credentials in your environment. Check the n8n license terms for your use, since commercial internal use and SSO features depend on the edition you choose. |
| Teams that need SSO, Git environments or log streaming | Self-hosted n8n Business or Enterprise | According to n8n's pricing page, these features are limited to the Business and Enterprise plans. Confirm the current edition terms with n8n before budgeting. |
| Flows with high volume of steps per run | Self-hosted n8n | n8n counts an execution as one run of a whole workflow regardless of step count, per its pricing page. Confirm how your own run volume maps to your chosen plan or server capacity. |
| Teams that need high availability for the automation runtime | Power Automate or self-hosted n8n Enterprise | Multi-main high availability in n8n is restricted to Enterprise self-hosted deployments. Smaller n8n editions need a different resilience plan. |
What n8n's Sustainable Use License allows and what needs a paid key
The first question for any self-hosted n8n plan is whether your intended use falls inside the Sustainable Use License. That license allows you to use and modify n8n for your own internal business purposes, or for non-commercial or personal use. It does not permit reselling n8n, offering it to third parties as a hosted or managed service, or distributing it for commercial gain. If your plan is to run n8n only for your own staff's Power Automate replacement flows, that is internal business use. If a business unit plans to run flows for customers or subsidiaries outside the legal entity, treat that as a separate question and put it to counsel before the design is fixed. Ask counsel to confirm the position against the license text in the n8n LICENSE file, not against a summary.
Files with .ee in their name or directory sit outside the Sustainable Use License and need a valid n8n Enterprise License. Your engineers should know this before they fork or patch the code, because modifying or deploying those files changes your license position. Without a license key, n8n runs as the free Community edition. Adding a Business or Enterprise license key enables those editions. The paid features that matter most for replacing Power Automate are SSO and LDAP, environments with Git for promoting flows between stages, and log streaming to your SIEM. Multi-main setup for high availability is restricted to Enterprise self-hosted deployments. Confirm each of these against the current pricing and feature tables before you decide, because editions and their contents change over time.
Build a decision list that maps each control you need to an edition. For example, if your identity team requires SAML or LDAP sign-in for every maker, that control alone points to a paid key, and the cost of that key is a recurring line in your business case. If you can accept local accounts and a single n8n instance with a documented recovery procedure, the Community edition may cover the first phase. Ask the n8n sales team for a written quote that names the edition, the self-hosted terms, the support level and any restrictions on the number of instances or environments, and have counsel review that paperwork alongside the license file.
Where data lives and who controls identity under each option
Power Automate cloud flows run in Microsoft's cloud and reach on-premises systems through a gateway, while self-hosted n8n runs wherever you deploy it. The cards below cover the decisions that follow from that split: where data sits, how identity is enforced, how keys and logs are handled, and which evidence you must assemble yourself.
Where cloud flow data sits
Power Automate cloud flows execute in Microsoft's cloud, so run history, connection references and any data passing through a flow are processed in the Power Platform environment's region. n8n runs in your own cloud account or data center, and the workflow data, execution history and credentials are stored in the database you provision. Before migrating, confirm in writing with Microsoft which regions your tenant's environments use, and map every flow whose payloads include personal or regulated data.
Gateway path versus internal network access
Power Automate reaches on-premises databases and file shares through the on-premises data gateway, so traffic leaves your network and passes through a Microsoft-managed service before it returns. A self-hosted n8n instance placed inside the same network can call internal systems directly, subject to your firewall rules. The trade-off is that you then own the network path, certificates and access rules that the gateway previously handled. Document each internal endpoint n8n will call.
Identity through Entra ID or SAML
Power Automate inherits sign-in from Microsoft Entra ID, so conditional access and MFA policies apply to flow makers automatically. On n8n, SSO and LDAP are included only in the Business and Enterprise plans, and SAML setup guides exist for Okta Workforce Identity and Azure AD. Confirm that your identity provider's claims map to n8n roles, and decide how you will remove access for leavers, since that process moves from Entra ID into a separate application.
Credential encryption key in queue mode
In n8n queue mode, the main instance's encryption key must be shared with every worker and webhook processor so they can decrypt credentials stored in the database. Losing or mismatching this key makes stored credentials unusable, and copying it to many hosts widens the set of systems that can read secrets. Store the key in your existing secrets manager, restrict who can read it, and test a restore from backup that includes it.
Audit trails and log streaming
Log streaming in n8n is included only in the Business and Enterprise plans, so the Community edition does not provide it. Power Automate records run history in the Microsoft portal and surfaces admin activity through Microsoft's audit tooling. Define the events you must retain, such as credential changes, workflow edits and failed executions, and confirm where each platform's logs are kept and for how long, since neither move automatically satisfies your retention rules.
Compliance evidence and who issues it
DeployOpen can prepare the configuration, access records, backup procedures and evidence that an assessment will examine for a self-hosted n8n deployment. DeployOpen does not issue audit reports, attestations or certifications, and neither Microsoft nor n8n's licensing grants you one by default. Ask your auditor which controls they will test, and ask Microsoft and n8n for their current compliance documentation before you rely on either for scope.
What happens to desktop flows that n8n cannot replace
n8n does not provide desktop RPA, so the desktop flows in your Power Automate tenant need a separate decision. A desktop flow drives a Windows application through its user interface, clicking and typing where no API exists. Before you plan a migration, list every desktop flow, the application it drives, and whether that application exposes an API, a database or a file export that could carry the same data. Those three answers decide which of the three paths below fits each flow. The first path is to rebuild the work as an API integration in n8n. This is usually the better fix when the target system has a documented API, because the flow then runs on the same canvas and credentials as your other automations. The second path is to keep the desktop flow on Power Automate. This keeps the work on a platform that already runs it, but the desktop flow still depends on the Power Automate licensing and on the machines and sessions that run it, so it stays on your cost and dependency list. The third path is to move the UI automation to an RPA framework. Confirm with your Microsoft account team which licenses cover the desktop flows you keep, and confirm the framework's own terms before you choose it.
The third path points to the sibling page on Robot Framework, an open source automation framework for testing and RPA. Moving UI automation to it changes more than the tool: you also need dedicated bot machines, their Windows images, session handling, credential storage and a scheduler to run them. Those machines are infrastructure you must patch, monitor and back up, and their cost recurs whether or not the bots are busy. Count them before you commit, and do not treat a desktop flow as migrated until a machine, an owner and a run schedule exist for it. For each desktop flow, record one of three outcomes: rebuilt as an n8n workflow, retained on Power Automate with a stated end date, or moved to a framework with named bot machines. Assign an owner to every retained flow so it does not quietly outlive your licenses or your review cycle.
Cost of ownership by option
Power Automate charges through several license types rather than one bill, so the total depends on who builds and runs flows, which connectors those flows call and how many desktop bots you operate. Most of these components recur each billing period, which means growth in makers, users or bots raises the cost every period. Ask Microsoft or your reseller to quote each component against your own tenant and flow inventory.
- Premium licenses per user: Makers and users who run flows that call premium connectors, HTTP actions or Dataverse typically need a per-user premium license. The count depends on the connectors each flow uses, not only on the number of people who open the designer.
- Process and Hosted Process per bot: Unattended desktop flows run on bots that are licensed per bot. Hosted Process runs those bots on Microsoft-managed machines, so ask whether your scenario needs it.
- Process Mining add-on: This is a separate add-on for process analytics. It only adds cost if you buy it.
- Free tier standard-connector limit: The free tier covers standard connectors only. Any flow that reaches a premium connector needs a paid license, so a flow that starts free can change cost category after a small edit.
- Which license covers attended desktop flows: Confirm in writing which license covers attended desktop flows and how it applies to your makers.
Check which connectors each flow uses and map each one to the license it requires, then confirm current terms with Microsoft before you compare totals.
The n8n Community edition is free to run, and the Sustainable Use License permits internal business use. Business and Enterprise features are enabled with a license key, so the license line is the main decision for self-hosted n8n. Per the n8n pricing page, all plans include unlimited users, workflows and integrations, and an execution counts as one run of a whole workflow regardless of its number of steps. Check the current n8n pricing page before you build a budget.
- Community edition: Free to self-host for internal business use. It does not include SSO, LDAP, Git-based environments, log streaming or multi-main high availability.
- Business license: Listed at 667 euros per month billed annually, and currently self-hosted only. It includes SSO and LDAP, environments with Git and log streaming.
- Enterprise license: Custom pricing for self-hosted or cloud. It adds dedicated support with an SLA and multi-main setup, which is restricted to Enterprise self-hosted deployments.
- Cloud plans for comparison: Starter and Pro are cloud plans at 20 and 50 euros per month billed annually. They run on n8n's infrastructure, so they do not replace the servers and database costs of a self-hosted install.
- Files under .ee: Files with .ee in their name or directory require an Enterprise License, so a Community install does not include them.
Confirm which features your flows and security team need, then match those features to the edition before you assume the Community edition covers the scenario.
Self-hosted n8n costs more in infrastructure than most buyers expect, because the platform needs compute, a database and backups that run continuously. Single-node installs use one application server and PostgreSQL, while queue mode adds Redis and a pool of worker processes that read and write PostgreSQL. Each of these components needs capacity, patching and monitoring, and the cost rises with execution volume, the number of workers and any high availability requirement.
- Application servers: Run n8n on virtual machines or containers, for example with Docker Compose or on Kubernetes. Size them for trigger volume, execution volume and peak load.
- PostgreSQL: Stores workflows, execution data and credentials. A managed database service or a self-run cluster both carry a recurring cost, and the choice affects backup and failover effort.
- Queue mode components: Queue mode passes executions through Redis to workers. Each extra worker adds compute, and the main instance's encryption key must be shared with every worker and webhook processor.
- Backups: Back up PostgreSQL and the encryption key together, and test restores. Without the key, stored credentials cannot be decrypted.
- Network and environments: Separate development, test and production installs add servers, databases and storage, and each one recurs.
Ask your platform team to price each of these components in your own cloud account or data center, including the database and backup storage, and check the sizing against your expected execution volume.
Power Automate removes most of the platform operations work from your team because Microsoft runs the service. Self-hosted n8n moves that work to you, and the largest recurring cost is usually staff time for upgrades, monitoring, access control and on-call response. There is also a one-time cost for installation, identity integration and rebuilding flows, which depends on how many flows you migrate and how complex they are.
- One-time build work: Installation, SSO configuration, credential setup and rebuilding flows in n8n are one-time efforts. Their size depends on the flow count and on how many connectors each flow touches.
- Upgrades: Plan a recurring upgrade cycle that reads the n8n release notes, tests workflows and schedules a change window. Upgrades on an untested install carry the most risk.
- Monitoring and on-call: Someone must watch execution failures, worker health, database capacity and certificate expiry, and respond when a flow stops.
- Support options: Enterprise includes dedicated support with an SLA. Ongoing support, upgrades and testing can also be bought as a retainer from DeployOpen, with scope and price agreed in writing.
- Skills in house: A team that already runs Node.js services and PostgreSQL carries less of this cost than one that does not.
Ask any implementation partner for a fixed-scope quote that lists build, handover and recurring operations separately, so you can compare that with the staff hours you already pay for Power Automate administration.
Questions buyers ask before choosing n8n over Power Automate
How much does moving off Power Automate to n8n cost?
The move cost depends on the number of flows, their complexity, the connectors they use and how many environments you run. Costs fall into one-time work (inventory, rebuilding flows, re-creating connections, testing, cutover) and recurring work (servers, PostgreSQL, backups, upgrades and support). On the n8n side, the Community edition is free to download, while Business and Enterprise are paid licenses; n8n's pricing page lists the Business plan at 667 euros per month billed annually and the Enterprise plan at custom pricing. On the Power Automate side, you pay per user or per bot for premium capabilities. Ask any implementation partner for a quote built from a written scope that lists the flows in scope, the connectors and the environments. The cost comparison page covers the component detail, and this page's sibling cost comparison breaks down each component line by line.
How long does a Power Automate to n8n migration take?
Duration scales mainly with flow count, flow complexity and the number of systems each flow touches. A small set of flows with standard connectors is a short project, while dozens of flows that use on-premises data gateway connections, approvals and custom connectors take longer. Time is also spent on parallel running, when both platforms execute the same process until outputs match. Start with an inventory of flows by owner and environment, because that list sets the scope. No fixed timeline is safe to assume before that inventory exists, so ask for a fixed-scope plan with agreed deliverables and dates before work starts.
Can our internal team run n8n without outside help?
Many teams can run n8n in-house if they already operate containers, a PostgreSQL database and a secrets process. Operating it well requires skills in Linux, Docker Compose or Kubernetes, database backup and restore, TLS, identity integration and monitoring. If you plan to scale with queue mode, your team must also manage Redis, worker pools and sharing the main instance's encryption key with every worker and webhook processor, because workers need it to read stored credentials. Multi-main high availability is limited to Enterprise self-hosted deployments. Before deciding, check whether your staff have these skills, who is on call, and whether an outside team should cover upgrades and testing under a retainer.
Does the n8n license allow our business to use it?
n8n's main codebase uses the Sustainable Use License, which permits use for your own internal business purposes and for non-commercial or personal use. Internal business use is the case most organizations need, but the license does not permit you to offer n8n as a hosted service to others or distribute it free of charge for commercial purposes. Files with .ee in their name or directory are not covered by that license and need a valid n8n Enterprise License. Have your legal counsel review the LICENSE.md file against your intended use, especially if you plan to run n8n for clients or subsidiaries.
How does n8n count executions compared with Power Automate?
n8n counts one execution as one run of a whole workflow, regardless of how many steps it contains. Power Automate's billing model differs: it meters actions and licenses per user or per flow, so a long flow costs more in action usage than a short one. This difference changes the bill for high-volume processes with many steps. Model your current monthly run volume and step counts against both pricing pages before deciding. Also confirm that self-hosting removes the execution cap on your own servers, since your limits then depend on hardware, database capacity and queue design.
Can Power Automate desktop flows move to n8n?
Not directly. Desktop flows automate legacy Windows applications by mimicking keyboard and mouse input, and n8n does not provide a desktop RPA capability. Where the target system exposes an API, the usual fix is an API integration in n8n instead of UI automation. Where it does not, the process may need a different tool, such as Robot Framework, plus bot machines to run it. Inventory each desktop flow and decide, system by system, whether an API, a database connection or a retained RPA tool is the right replacement.
Which Microsoft 365 connectors are missing in n8n?
Power Automate has deep, first-party connectors for Microsoft 365 services such as Outlook, SharePoint, Teams and Dataverse, and n8n integrates with those services through its own nodes and the Microsoft Graph API. Check each connector your flows use against the n8n node catalog, because coverage, trigger types and authentication options can differ. Confirm specifically how approvals, Dataverse triggers and on-premises gateway connections will be replaced before you commit to a scope. Also check the n8n SAML single sign-on requirements, which are available on Business and Enterprise plans.
How a move from Power Automate to n8n is structured
The sequence turns a set of Power Automate cloud flows into a tested, self-hosted n8n estate with known owners, working connections and a documented cutover. Each step produces a record that the next step depends on.
Inventory flows by owner and environment
List every cloud flow across your Power Platform environments, with its owner, the connectors it uses, its triggers, its run frequency and whether it is still in use. Flag flows that depend on an on-premises data gateway, a custom connector or an approval step. Ask the platform team to confirm which environments hold production flows. The step is done when every flow has an owner, a business purpose and a go or retire decision.
Export packages and solutions as reference
Export each flow as a package and export the relevant Dataverse solutions, then store them in a controlled repository. Treat these files as reference documentation of triggers, actions and expressions, not as deployable artifacts, because they do not import into n8n. Confirm with the flow owners that the exports match the latest published version. The step is done when every retained flow has an archived export and its inventory entry links to it.
Rebuild triggers and actions in n8n
Recreate each retained flow as an n8n workflow, mapping each trigger and action to an n8n node or an HTTP request against the target API. Keep the logic of conditions, loops and error handling, and document where a Microsoft 365 connector has no direct equivalent so it needs an API call instead. Developers and flow owners review the workflow together. The step is done when each workflow has a reviewed design note and its node list matches the exported reference.
Replace gateway connections with internal network access
Where a Power Automate flow reached an on-premises system through the on-premises data gateway, place the n8n instance or its worker inside the network segment that can reach that system and connect directly. Review firewall rules, service accounts and network paths with the security team, and keep the n8n editor and webhook endpoints on separate, controlled entry points. The step is done when each gateway-dependent workflow runs against its internal target and the gateway dependency is removed from the inventory.
Recreate connections and credentials
Power Automate connections do not move with exports, so create each credential in n8n using the least privilege account the integration needs, and record the owner and rotation process in your inventory. Where you run queue mode, the encryption key must be shared with every worker and webhook processor so they can read stored credentials, so manage that key under your secrets process. The step is done when every workflow's credentials are present, tested against a non-production target and owned by a named person.
Test workflows against production-like data
Run each rebuilt workflow against non-production data and compare its outputs, record counts and error paths with the Power Automate original for the same inputs. Check failure handling, retries, duplicate protection and timezone behavior, which often differ between platforms. Business owners sign off on results. The step is done when each workflow has a test record showing matching outputs or a documented, approved difference.
Run both platforms in parallel
Keep the Power Automate flows and the n8n workflows active side by side for an observation period agreed with the flow owners, and make sure only one side writes to shared systems at a time. Compare run logs and downstream results daily, and fix any gaps. Confirm the observation period in writing before starting, since the length depends on your business cycles. The step is done when logs show consistent results across the agreed period with no unexplained differences.
Switch off Power Automate flows
Disable each Power Automate flow only after its n8n replacement has passed parallel running and its owner has approved the cutover. Remove or revoke the related connections and gateway registrations, update the inventory, and keep the archived exports for the retention period your records policy requires. Confirm with your licensing contact which Power Automate and Power Platform licenses to release at renewal. The step is done when the inventory shows every flow as switched off or retired, and the access revocations are logged.
When staying on Power Automate is the better decision
Staying on Power Automate is the better decision when most of your flows run against Microsoft 365 and Dataverse, when your makers already work in the Power Platform, or when desktop automation is central to how work gets done. In those cases, the connector depth and native identity integration of the Microsoft stack usually outweigh the licensing friction. Before deciding, list your critical flows and confirm, for each one, that every trigger and action has a maintained connector in Power Automate and an equivalent or a custom HTTP route in n8n. Connector coverage for Microsoft 365 services such as Outlook, SharePoint, Teams and Excel is the first thing to check, because a flow that depends on a Dataverse table, an approval or a Teams adaptive card may have no drop-in replacement. Check the current connector list in Microsoft's documentation rather than relying on memory, since connector names and actions change.
Desktop flows are the second deciding factor. Power Automate desktop flows drive legacy Windows applications through the user interface, and n8n does not provide an equivalent for that. If a business process depends on a thick client with no API, moving only the cloud flows leaves the desktop work behind on the Power Automate licence and the machines that run it. Confirm which desktop flows exist, which machines run them and whether those machines are attended or unattended. A separate page covers how Robot Framework fits when desktop automation must be replaced, so that decision should be made deliberately rather than by default. The third factor is hosting. Power Automate runs in Microsoft-managed cloud infrastructure, and many organizations prefer that operating model because Microsoft handles patching, availability and the platform's runtime. Self-hosting n8n moves those duties to your team, including PostgreSQL backups, upgrades and the encryption key that n8n requires for stored credentials. If your governance model requires Microsoft to operate the runtime, or your team lacks capacity to run it, that requirement settles the question. Ask your Microsoft account team and your licence reseller to confirm current per-user and per-flow terms in writing before comparing them with n8n's editions.
How DeployOpen helps you evaluate, implement and migrate n8n
DeployOpen plans, implements, hardens, backs up and documents self-hosted open-source platforms inside your own cloud accounts, data centers or air-gapped networks.
