n8n vs Node-RED: which to choose

Should you choose n8n or Node-RED for self-hosted automation?

Choose n8n when the work is business app automation across many SaaS and internal systems, and Node-RED when the work is event-driven, IoT or edge flows that move messages between devices, protocols and services. n8n advertises more than 1,500 integrations and a visual canvas that accepts custom JavaScript or Python, which suits operations and business teams connecting CRMs, ticketing tools and databases. Node-RED's flow library holds over 5,000 community-contributed nodes, and its JSON flows and Node.js runtime suit sensor data, MQTT-style messaging and edge hardware. The first advantage matters most when your automations touch many cloud applications. The second matters most when your flows run close to machines or handle continuous event streams.

The decision turns on three questions. First, license: n8n's Sustainable Use License allows internal business, non-commercial or personal use, and it is not an OSI open source license. If you plan to embed the tool in a product you sell or offer it to customers, have counsel read the license text against your use, and check the .ee files, which need an n8n Enterprise License. Node-RED is Apache-2.0 under the OpenJS Foundation, so embedding and redistribution are governed by a standard permissive license. Second, workload shape: confirm whether your traffic is webhook and API driven at business volume, which points toward n8n queue mode with Redis and workers, or sensor and message streams that need low-latency local processing. Third, people: decide whether analysts and business owners will build flows in a browser, or whether an engineering or OT team will own them, and plan who patches, backs up and secures each instance.

Security should shape the rollout in either case. The Node-RED editor is not secured by default, so anyone who can reach its address can deploy changes, and the Securing Node-RED guide describes HTTPS and authentication for the editor and admin API. For n8n, confirm which identity features your edition includes, since SAML single sign-on sits in the Business and Enterprise plans, and confirm the queue mode encryption key handling before you add workers. Run a short pilot with one real flow from each candidate, measure who needs to edit it, and record the license and identity answers in writing before you commit.

Which platform fits which scenario

This table maps common scenarios to the platform that fits them better and the condition that drives the choice. Read each row against your own team, data sources and licensing constraints, since the condition column is what should decide the shortlist.

Scenario	Better fit	Why
Business SaaS automation with many app integrations	n8n	n8n advertises more than 1,500 integrations as scale context, and its canvas is built for business app workflows like CRM sync, ticket routing and notifications. Confirm each specific app connector you need in the current catalog.
IoT and device telemetry flows	Node-RED	Node-RED is built around event-driven flows with a Node.js runtime and has run on small hardware such as Raspberry Pi. Its community library of over 5,000 nodes is scale context, so check that the device protocols you need have maintained nodes.
Event-driven integration inside an existing Node.js estate	Node-RED	If your team already runs Node.js services, Node-RED adds a JSON-stored flow runtime that sits alongside them. The condition is whether your engineers will maintain flows in the browser editor as part of normal operations.
Team embeds automation into a commercial product	Node-RED	Node-RED is Apache-2.0 licensed, which permits embedding under its permissive terms. n8n's Sustainable Use License limits use to internal business, non-commercial or personal purposes, so confirm with counsel before embedding n8n.
Internal-only operations automation	n8n	When flows run only for your own staff, n8n's Sustainable Use License permits internal business use. Queue mode with Redis and workers covers higher execution volume, but plan the encryption key and database sharing it requires.
Team with no developers	n8n	n8n's visual canvas lets non-developers build and maintain business flows, and custom JavaScript or Python is available when needed. Confirm which editor features your admins need on the free edition, since SSO and environments are paid.
Team with Node.js skills	Node-RED	Node-RED flows are stored as JSON and extended with Node.js nodes, which suits developers who want to version and extend the runtime. Confirm how your team will manage flow files and editor security before rollout.

How n8n and Node-RED are built and what that means for operations

n8n and Node-RED both run on Node.js and both give builders a visual canvas, but they differ sharply in how many processes they run and who keeps them alive. The cards below cover the runtime shape of each platform and the operational work each shape creates for the team that owns it.

n8n as a TypeScript and Node.js app

n8n is built with TypeScript and Node.js and combines a visual canvas with custom JavaScript or Python code inside workflow steps. That mix lets a team extend flows beyond the built-in nodes, but it also means custom code runs inside the platform's runtime. Before you commit, check which code paths your builders will use, who reviews them, and whose Node.js and Python versions the instance must carry.

Regular mode runs one process

In regular mode, a single n8n process handles triggers, webhooks and executions together. It is the simplest layout to install and back up, and it suits small teams with modest volumes. The trade-off is that a heavy execution can compete with webhook handling on the same process, so monitor load before you hand critical automations to one instance.

Queue mode needs Redis and PostgreSQL

In queue mode, the main instance keeps timers and webhooks, passes execution IDs to Redis, and separate workers run the executions and write results to PostgreSQL. This splits the load and lets you add workers, but it adds Redis as a component you must patch, monitor and restore. Ask whether your team already operates Redis and PostgreSQL highly available, because queue mode without them moves the failure points rather than removing them.

Shared encryption key across processes

In queue mode, the main instance's encryption key must be available to every worker and webhook processor, because they read credentials stored in the database. Key handling becomes a cross-process concern: a key mismatch or a key copied carelessly to many hosts widens the blast radius of a leak. Plan where the key lives, how it is rotated, and which secrets manager, if any, holds it before you add nodes.

SQLite is not a queue mode option

Running n8n queue mode on SQLite is not recommended, so the database choice is decided by the scaling model, not by convenience. A single-file database may suit a regular-mode trial, but any move toward workers means PostgreSQL. Treat the database as a planned migration target from day one, since moving data later adds work to a project that already depends on live automations.

Node-RED as a browser editor on Node.js

Node-RED pairs a browser editor with a Node.js runtime and stores each flow as JSON, which makes flows easy to export, diff and keep in version control. The runtime is one process that your team installs and maintains directly. Confirm that your operators can read and edit the JSON, and decide how flow changes move from a developer's browser to a production instance.

Install paths from npm to Docker

Node-RED documents installs with npm locally, an install script on Raspberry Pi, Docker, BeagleBone boards, Termux on Android (experimental) and several cloud platforms. That range suits edge and lab deployments, but the install method sets your patching and backup routine. Node-RED 5.0 requires Node.js 22.9.0 or later, with Node.js 24 recommended, and a 64-bit OS, so Raspberry Pi 3B and older models are no longer supported.

How n8n and Node-RED compare on the capabilities that decide the choice

This table sets n8n against Node-RED on the capabilities that usually settle a shortlist, including license, scaling, identity and editor security. Read each row against your own use case, and check the plan or setup conditions noted in each cell before assuming a feature is available.

Capability	n8n	Node-RED
License	Sustainable Use License, not OSI open source. Internal business, non-commercial or personal use only. Files with .ee in the name need an n8n Enterprise License.	Apache-2.0, governed by the OpenJS Foundation. Permits broader use under the license terms, so confirm your embedding or resale position with counsel.
Integration catalog	Advertises more than 1,500 integrations, with all integrations included on every plan.	Over 5,000 community-contributed nodes, with quality and maintenance varying by node author.
Primary use case	Business app and API automation, built visually with custom JavaScript or Python code where needed.	Event-driven and IoT flows, with a browser editor backed by a Node.js runtime.
Scaling model	Queue mode: the main instance handles triggers and webhooks, Redis passes executions, and workers write results to PostgreSQL. Not recommended on SQLite.	Single Node.js runtime by default. Confirm the scaling pattern you need with the Node-RED documentation and your own architecture.
High availability	Multi-main setup is available only on Enterprise self-hosted deployments, not on Community or n8n Cloud.	No built-in multi-instance high availability is documented in the supplied sources. Confirm the approach with the vendor or FlowFuse.
Single sign-on	SAML SSO and LDAP are included on Business and Enterprise plans. Setup guides cover Okta Workforce Identity and Azure AD.	Editor and admin API can use OAuth and OpenID authentication through Passport, configured by you in the runtime settings.
Editor security	Access to the editor is governed by the n8n user management model, which requires a plan with SSO or LDAP for centralized control.	Editor is not secured by default, so anyone who can reach the IP address can deploy changes. Enable HTTPS and authentication before exposing it.
Custom code	Custom JavaScript or Python inside workflows. Custom nodes and bash scripts are self-hosted only, per n8n's pricing page.	Custom nodes are written as Node.js packages and flows are stored as JSON, so changes can be reviewed in source control.
Supported install targets	Self-hosted on your infrastructure, n8n Cloud in Frankfurt, or the free Community edition. Confirm the container and host options in the n8n documentation.	Local npm install, Raspberry Pi install script, Docker, BeagleBone, Android through Termux (experimental), and cloud platforms including AWS and Microsoft Azure. Raspberry Pi 3B and older are not supported in 5.0.

What the n8n and Node-RED licenses allow and what is paid

n8n is licensed under the Sustainable Use License, which is a fair-code license and not an OSI open-source license. It permits use and modification for your own internal business purposes or for non-commercial or personal use. Distribution is allowed only free of charge and only for non-commercial purposes, so a plan to sell n8n itself, or a product built on it, to customers falls outside the grant. Read the terms in the n8n LICENSE.md file as the controlling text.

Enterprise files: Files with .ee in their name or directory are not covered by the Sustainable Use License and require a valid n8n Enterprise License, so a fork or build that includes them needs that license too.
Paid plan features: According to n8n's pricing page, SSO and LDAP, environments with Git, and log streaming are included only in the Business and Enterprise plans.
Business tier scope: The Business plan is currently self-hosted only, and it is billed annually at the list price shown on the pricing page.
Multi-main high availability: Running several main instances is restricted to Enterprise self-hosted deployments, so a Business or Community setup has a single main instance.
Who pays for what: The Community edition is free to download, but your team carries hosting, upgrades, backups and any support you buy separately.

Ask n8n in writing which features your chosen plan includes and whether the .ee code paths touch the features you need.

How SSO and editor security differ in n8n and Node-RED

The main difference is where identity controls come from. In n8n, SAML single sign-on sits on the Business and Enterprise plans, and the n8n documentation includes step-by-step setup guides for Okta Workforce Identity and Azure AD. LDAP is in the same paid tier, so a team on the free Community edition should not plan on directory-backed login without a paid license. Confirm the exact attribute mapping, group handling and role assignment your identity provider needs against the n8n SAML user management docs before you assume the setup fits your directory.

Node-RED takes a different starting point. The editor is not secured by default, so anyone who can reach the host's IP address can deploy changes to a running flow. Before exposing it beyond a lab, you need to turn on the controls the Node-RED security guide describes: HTTPS, a username and password, or OAuth and OpenID authentication through Passport for both the editor and the admin API. Basic authentication can also protect HTTP nodes. Each option is set in the runtime configuration, so the work is owned by your team rather than supplied by a license tier, and it should be reviewed in the same change as network exposure.

Before deciding, confirm which identity provider and login model your team must use, including whether SSO is mandatory for editor access, whether group-based roles are needed, and who approves changes. Then test each platform against that requirement: check n8n's SSO against your plan tier and cost, and check whether Node-RED's Passport options accept your provider without custom code. Ask your security team how each tool's admin access will be logged and reviewed, since neither choice removes the need for network restriction and regular access reviews.

What drives the running cost of each platform

Running n8n and Node-RED costs differ less in license fees than in the infrastructure, skills and upgrade work each one asks for. The cards below separate what recurs from what is paid once, and what to put in a quote before you commit.

Infrastructure footprint

A self-hosted n8n instance in regular mode is one process, but queue mode adds a main instance, Redis, a pool of workers and PostgreSQL, each of which needs hosting, patching and backups. Node-RED runs on modest hardware, including a Raspberry Pi where the operating system is 64-bit, so its footprint is usually a single Node.js process. Ask your team to size the n8n worker pool and database for your expected execution volume before comparing hosting bills.

Build and maintenance skills

n8n builds mostly on the visual canvas, so business analysts and integration staff can produce many workflows without writing code, although custom JavaScript or Python is available when a node does not fit. Node-RED flows are stored as JSON and extended with JavaScript function nodes, which suits developers and IoT engineers comfortable with Node.js. Staffing cost follows the people who will own the flows after go-live, so count who will debug them in production.

Vendor fees and cloud plans

Self-hosted n8n Community use is free, and n8n's pricing page lists Starter and Pro cloud plans at 20 euros and 50 euros per month billed annually, a Business plan at 667 euros per month billed annually that is currently self-hosted only, and Enterprise at custom pricing. These are execution-based fees for cloud plans, while self-hosted Business or Enterprise licensing is a separate quote. Node-RED has no vendor license fee in its core, so its recurring cost is infrastructure and staff time.

Upgrade effort

Node-RED 5.0 was released on June 9, 2026 and requires Node.js 22.9.0 or later, with Node.js 24 recommended, and it no longer supports Raspberry Pi 3B and older models. Moving a fleet of edge devices or a server to this line means checking Node.js versions, installed community nodes and any hardware that falls outside the new requirements. Plan upgrade windows for both the runtime and the third-party nodes your flows depend on.

Commercial support and services

Node-RED is governed by the OpenJS Foundation, and FlowFuse, Inc. offers enterprise and industrial services built on Node-RED, so support can be bought from a vendor or handled in-house. n8n support scope depends on the edition: Enterprise adds dedicated support with an SLA, and multi-main high availability is restricted to Enterprise self-hosted deployments. Ask each vendor what support, response commitments and upgrade help are included in the price you are quoted.

Quote scope for DeployOpen

DeployOpen does not publish a price list. Most engagements are fixed-scope, with scope, deliverables and timelines agreed in writing before work starts, and ongoing support, upgrades and testing are available as retainers. When requesting a quote, ask for the platform components, number of environments, expected execution volume, hardening and backup work, upgrade plan and which retainer hours are included.

How to move flows from n8n to Node-RED or back

This sequence turns a loose set of n8n workflows and Node-RED flows into a tested, signed-off move, with each step ending in a documented check. It is built around the logic, triggers and integrations you need to keep, because the flow files themselves do not carry over.

Inventory flows, triggers and credentials
The platform owner and the flow authors list every active n8n workflow or Node-RED flow, with its trigger type (schedule, webhook, queue or device input), the external systems it calls, and the credentials it uses. Record who owns each flow and how often it runs. You are done when every production flow has one line in a shared inventory and each credential is tied to a named owner and a system. This list is the main driver of switching cost, so it should be complete before any building starts.
Map each trigger and integration to target nodes
For each inventory line, the engineer finds the equivalent in the target platform. n8n's 1,500-plus integrations rarely map one to one onto Node-RED's community nodes, so some flows will need a generic HTTP or custom function step instead. Note where a flow uses n8n's code steps in JavaScript or Python and decide whether that logic is rewritten, moved to an external service, or dropped. You are done when each flow has a mapping sheet that flags every gap as a rebuild, a replacement or a retirement.
Rebuild credentials in target secret handling
Credentials are re-entered or re-issued in the target platform, not exported from one to the other. In n8n, credentials are encrypted with the instance encryption key, and in queue mode that key must be shared with every worker and webhook processor. In Node-RED, secrets live in the runtime configuration, so confirm where they are stored and who can read them in your environment. Rotate any secret that a former platform held. You are done when each mapped flow authenticates from the target and the old credential list is marked for revocation.
Rebuild webhooks and editor access controls
Webhook URLs change when a flow moves, so the upstream callers must be updated and tested. Separately, the editor needs its own access model: Node-RED's editor is not secured by default, so the team enables HTTPS and authentication through the documented Passport options before any flow is deployed, and confirms that only named administrators can reach the admin API. In n8n, confirm which roles and SSO option your edition provides for editor access. You are done when a test request reaches each rebuilt endpoint and an unauthenticated request to the editor or admin API is refused.
Run both platforms in parallel for a test window
Keep the source platform live and send the same inputs to the rebuilt flows in a staging or shadow setup. Compare outputs, error handling, retry behavior and the data written to downstream systems for a period the business owner agrees in advance. Where a flow writes to a system of record, use a non-production target to avoid duplicate writes. You are done when a written comparison shows matching results for each flow, and each difference has a documented decision.
Retire the old platform after sign-off
The business owner, security lead and flow owners sign off each flow, then the team switches traffic to the target and disables the source flows. Keep backups of the source exports and the inventory for the audit trail, and remove credentials and encryption keys from the retired platform. If the move is reversed later, the same inventory and mapping sheet are the starting point. You are done when the source platform has no active triggers, its credentials are revoked, and the sign-off record is filed.

Where n8n and Node-RED implementation projects usually run long

On n8n, the longest stretch is usually queue mode, not the first workflow. Moving from a single process to a main instance, Redis and separate workers means provisioning Redis, a PostgreSQL database that all processes share, and a worker pool sized for your execution volume. The step teams most often miss is the encryption key: the main instance's key must be shared with every worker and webhook processor so they can read credentials stored in the database. Plan a key distribution and rotation procedure before the first worker starts, and confirm with n8n how your chosen layout handles it. SQLite is not suitable for queue mode, so the database decision belongs in the design phase.

Identity and environment setup is the second source of delay. SAML single sign-on, environments with Git, and log streaming sit on the Business and Enterprise plans, so the plan decision has to precede the identity work. Role mapping from your identity provider, project ownership and credential sharing rules then take real review time with security and the workflow owners. Multi-main high availability is restricted to Enterprise self-hosted deployments, so confirm the license scope before designing for it. Credential governance also recurs: workflows built by business users can reach production systems quickly, so agree naming, ownership, review and offboarding rules for credentials before the canvas opens to them.

On Node-RED, the editor is not secured by default, so anyone who can reach the IP address can deploy changes. Securing it through HTTPS, username and password or OAuth and OpenID authentication via Passport, and basic authentication for HTTP nodes, should be a gate before any network exposure, and the Securing Node-RED guide is the starting point. Node-RED 5.0 requires Node.js 22.9.0 or later, with Node.js 24 recommended, and a 64-bit OS, so older Raspberry Pi hardware may need replacing before the upgrade. The library of more than 5,000 community nodes adds vetting work: each package needs a review of its maintenance, dependencies and permissions before it reaches an industrial or edge deployment. Fixed-scope work is agreed in writing before it starts, and timelines depend on your environment, the number of flows and the vetting depth you require.

Questions buyers ask before choosing n8n or Node-RED

What does the Sustainable Use License mean for an internal team versus a product we resell?

For an internal team, n8n's Sustainable Use License generally permits use and modification for your own internal business purposes, so running n8n to automate your own operations is the common case it covers. Resale and distribution are the main limits: the license allows distribution only free of charge for non-commercial purposes, so embedding n8n in a product you sell, or offering it as a service to customers, needs a separate conversation with n8n. Files with .ee in their name need a valid n8n Enterprise License regardless of use. Node-RED is Apache-2.0, which permits commercial use and redistribution under its terms. Have your legal team read the n8n license text and confirm your exact use case with n8n in writing before you commit.

Can Node-RED serve as a production business automation tool?

Node-RED can run in production, but it was built for flow-based event and IoT integration, so the fit depends on what you automate. Its strengths are wiring devices, message streams and APIs through over 5,000 community-contributed nodes, with flows stored as JSON. Business app automation with many SaaS connectors, approval steps and non-developer builders is where n8n's catalog of more than 1,500 integrations is the closer match. Node-RED's editor is not secured by default, so anyone who can reach it can deploy changes until you enable HTTPS and authentication through Passport. Confirm the node packages you depend on, their maintenance status and your support route, including FlowFuse's commercial offerings, before you decide.

What does n8n queue mode require beyond the main instance?

Queue mode needs more than one process and a shared message layer. The main instance handles triggers and webhooks and passes executions through Redis to a pool of worker processes, which read and write workflow data in PostgreSQL. Every worker and webhook processor must share the main instance's encryption key so they can read stored credentials. The n8n documentation advises against running queue mode on SQLite. High availability with several main instances is an Enterprise self-hosted feature, not available in the Community edition. Ask n8n to confirm current requirements for your version, and plan for backups of the database and the key.

What skills does our team need to run n8n and Node-RED?

Node-RED needs people comfortable with JavaScript and Node.js, since custom nodes and function logic are written in JavaScript, and Node.js 22.9.0 or later with Node.js 24 recommended for Node-RED 5.0. n8n also accepts custom JavaScript or Python code, but most workflows are built on the canvas, so builders can be less technical. Running n8n in queue mode calls for DevOps skills in Redis, PostgreSQL, container or host management, secret handling and upgrades. On the access side, network owners must decide who reaches the editor and admin API, and identity owners must set up SAML SSO, which is limited to Business and Enterprise plans. Map these roles before you pick a tool.

Can our team set this up and run it without outside help?

A team with DevOps and JavaScript experience can usually install either tool, but the harder work is production hardening: queue mode, backups, encryption key management, editor authentication, SSO and upgrade testing. Node-RED's editor needs HTTPS and authentication enabled before any network exposure, and n8n queue mode needs a tested database, Redis and worker layout. If your team lacks these skills or capacity, you can hire an implementation partner. DeployOpen plans, implements, hardens, backs up, upgrades and documents self-hosted platforms inside your own infrastructure, usually under a fixed-scope agreement. Ask any partner for a written scope, deliverables and timeline before work starts.

What drives the cost and time of running n8n or Node-RED?

Software licensing is only part of the cost. For n8n, the free Community edition has no license fee, but SSO, Git environments and log streaming need the Business plan, which n8n lists at 667 euros per month billed annually and self-hosted only, and Enterprise is custom priced. Node-RED is free under Apache-2.0, so its costs are infrastructure, integration build time and support. Recurring costs include hosting, Redis and PostgreSQL operations, upgrades and staff time. Time rises with the number of integrations, custom nodes, environments and security requirements. Ask each vendor for current pricing and edition terms, and ask any implementation partner for a fixed-scope quote based on your written requirements.

How do we secure editor access in each tool?

Start by treating the editor as an administrative surface. Node-RED does not secure its editor by default, so you should enable HTTPS and a username and password or OAuth and OpenID authentication through Passport for the editor and admin API, and apply basic authentication to HTTP nodes where needed. In n8n, SAML single sign-on is available on Business and Enterprise plans, with setup guides for Okta Workforce Identity and Azure AD. Network owners should restrict which hosts reach the editor, and security teams should review credential storage and the encryption key handling in queue mode. Confirm these controls against your own identity provider and threat model.
