Notion vs Outline: when each option fits a wiki-first team
If your team uses Notion mainly as a wiki and document space, the question is rarely whether Outline can hold your pages. The question is whether you need to control where those pages live and who pays for each seat, and whether you can accept the license terms and server work that come with a self-hosted option. Notion remains the better fit when you want hosted convenience, when Notion databases are central to how you work, and when no one on your team can take on running a production server. Its exports are broad: pages and databases can be exported as PDF, HTML, Markdown or CSV, and workspace owners can export all content, a process Notion says can take up to 30 hours. Those features matter if you plan to leave later, so confirm which plan and workspace settings apply to your exports before you commit.
Outline fits a team that wants a self-hosted wiki, values the Notion importer, and has dev-ops capacity to run the service. Outline's Notion importer is available in all editions from v0.83.0, so you do not need a paid license to bring pages across. The self-hosting requirements are concrete: PostgreSQL 14+, Redis 4+, at least 512MB of memory with 1GB or more recommended, a dedicated domain and an authentication provider. Outline does not support email and password login natively, and SAML is limited to its licensed Business and Enterprise editions, so plan identity integration early. Outline's own documentation says it requires dev-ops experience to run in production. Ask whoever will operate it to walk through the requirements page before you start.
Which option fits which scenario
This table maps six common situations to the option that usually fits better, along with the condition that changes the answer. Read each row against your own Notion footprint, identity setup and hosting constraints. The main takeaway is that licensing, how much of your content lives in databases and the capacity to run the platform usually decide the choice more than feature lists do.
| Scenario | Better fit | Condition that makes it so |
|---|---|---|
| Mostly static wiki pages with few databases | Outline | Pages convert cleanly through Outline's Notion importer, which is available in all editions from v0.83.0. Test a sample of pages from each Notion space before committing to a cutover date. |
| Heavy use of Notion databases | Neither alone; plan a separate table tool | Outline is built around documents, so trackers and tables need a relational tool such as Grist or Baserow. Confirm exactly how Outline's importer handles each database before you rely on it. |
| Hard data residency requirement | Either self-hosted option, chosen on license terms | Both run in your own infrastructure, so residency is met by where you host. Outline's license forbids offering it as a document service to third parties, so ask counsel whether your use is internal only. |
| No in-house ops capacity | Neither is hands-off; decide on support model | Outline requires PostgreSQL 14+, Redis 4+, a dedicated domain, an authentication provider and dev-ops experience. Without that skill set, budget for a fixed-scope implementation and a support retainer. |
| Plan to offer the wiki to outside customers | Neither Outline nor an unreviewed copyleft option | Outline's license prohibits a commercial document service for third parties. If you need that model, review a permissive option such as BookStack (MIT) or La Suite Docs (MIT) with counsel. |
| SAML is a hard requirement | Outline licensed edition, or confirm SAML in the other tool | Outline's SAML login is limited to its paid Business and Enterprise editions. If your identity provider supports OIDC, Outline's community edition may cover sign-in, so check that first. |
What Outline's Business Source License 1.1 allows and forbids
Outline is source-available under the Business Source License 1.1, not under an open-source license. The project's own license file says the BSL is not an open-source license, and the Open Source Initiative does not approve it. In practice this means you can read the code, run it, and modify it for permitted purposes, but the license does not give you the freedoms that an OSI-approved license such as AGPL-3.0 or MIT gives. Treat this as a governance decision for your architecture review, not a footnote, and record it in the same file as your other licensing decisions for the wiki.
The restriction that matters most is the ban on using Outline as a Document Service, which the license defines as a commercial offering that lets third parties create their own teams and documents. Outline's hosting documentation goes further and says that selling, reselling or hosting Outline as a service breaches the BSL terms and automatically terminates your license rights. Internal use by your own employees, contractors and business units is the typical fit. If you are considering a customer-facing portal, a managed service for other companies, or a reseller arrangement, that use case falls outside the grant. Have counsel confirm how your use case maps to the license text before you commit.
The license also sets a fixed conversion date. Each release converts to Apache License 2.0 on its change date, and for version 1.11.0 that date is October 12, 2030. Until then, the BSL terms apply to that version, so an internal wiki running 1.11.0 will still be under the BSL in the years your roadmap covers. Ask counsel whether the internal-use position needs written confirmation, and check the license file for the change date of any later release you deploy, since each release carries its own date.
How data location, identity and compliance change with self-hosting Outline
Notion keeps your workspace content, permissions and sign-in inside a vendor-run service. Self-hosting Outline moves those decisions into your own cloud account or data center, along with the work of proving how they are controlled. The cards below cover where content lives, how people sign in, which features sit behind a paid license, who owns backups and what evidence you must assemble.
Where content lives
Notion stores your pages and databases in its own hosted service, so the storage location is set by the vendor's hosting arrangements rather than by you. With Outline, the pages sit in your PostgreSQL database and in local or S3-compatible file storage that you provision. Confirm which region and account hold each store, who holds administrative access to the database and buckets, and whether any attachment or search index is replicated outside that boundary.
Identity without email and password
Outline does not support email and password sign-in natively. You must connect an external provider such as Google, Microsoft Entra, Slack, OIDC, Discord, GitLab, passkeys or email magic link. Decide which provider is the source of truth for joiners and leavers before go-live, because account removal in the identity system is what cuts off access to your wiki.
SAML limited to paid editions
SAML login is available only in Outline's licensed Business and Enterprise editions, so the community build cannot use it. If your Notion setup relies on SAML single sign-on, price the paid license into the comparison and confirm its terms directly with Outline. Check whether your identity policies, such as mandatory SSO for all users, depend on SAML rather than OIDC.
Backup responsibility moves to you
On Notion, the vendor operates the service, but you still depend on exports for your own copies. With self-hosted Outline, your team owns database backups, file storage backups, restore testing and retention. Define recovery objectives, keep backups outside the production account where your policy requires it, and test a full restore of PostgreSQL and attachments together so pages and their files stay consistent.
Compliance evidence you assemble
Self-hosting gives you direct control over configuration, access reviews, logging and change records, but it also means you must produce the evidence yourself. DeployOpen prepares the controls, documentation and evidence for a compliance assessment. Independent auditors and certification bodies issue any audit report, attestation or certification, so ask your assessor early which evidence they will accept.
What running Outline in production involves
Running Outline in production is an infrastructure project, not a file copy. Outline's hosting documentation describes two installation paths, Docker and installation from source, and the team should choose one based on how it already builds and patches services. Outline self-hosts only on Unix-compatible systems, so a Windows-only server estate is a blocker to settle before any other planning. The core dependencies are PostgreSQL 14 or later for content and metadata and Redis 4 or later for caching and realtime coordination. Both need backup, patching and monitoring that match the organization's standards for databases it already operates.
Memory and network decisions come next. Outline's requirements document sets a minimum of 512MB of memory and recommends 1GB or more, but those are starting points for a single instance, not sizing for a large or busy workspace, so load-test with realistic page counts before committing. Outline also needs a dedicated domain, which affects DNS, TLS certificate management and how the authentication provider's redirect URLs are registered. For files, Outline supports local storage or S3-compatible object storage. Local storage is simpler but ties attachments to one host, while S3-compatible storage lets the team place attachments in a store it already runs and back up separately.
Scaling and staffing are the decisions most often underestimated. Outline's hosting documentation covers horizontal scaling, which means running several application instances behind a load balancer, and the vendor states that running Outline in production requires dev-ops experience. Confirm before go-live who owns upgrades, since each new release such as v1.11.0 may change configuration or require database migrations, and who handles restore testing for PostgreSQL and attachment storage. Ask whether your team can operate Redis, object storage and the authentication integration on an ongoing basis. If not, that gap should be priced into an implementation or support scope before the migration plan is approved.
What drives the total cost of each option
Why does Notion's cost depend on how many members you have?
Notion is a per-member subscription, so the recurring bill grows with every seat and changes with the plan tier you choose. SAML single sign-on is a Business tier feature, so an organization that needs it must pay for that tier rather than a lower one. Confirm current plan names, seat prices and which features sit in each tier directly with Notion, because these change and this page does not state them. Ask your finance team to model seat counts for the next two renewals, including guest and external users.
What does self-hosting Outline cost in infrastructure?
Self-hosted Outline is paid for through the servers and services you run it on, not through a per-seat fee. Outline requires PostgreSQL 14 or later, Redis 4 or later, at least 512MB of memory (1GB or more recommended), a dedicated domain and an authentication provider. Your recurring infrastructure cost covers compute, database and cache hosting, file storage (local or S3-compatible), backups and network egress. Ask your platform team to price these components in the environment where they already operate, since the figure depends on your cloud account or data center.
When do Outline's paid Business or Enterprise licenses add cost?
The community edition of Outline is free to run under the Business Source License 1.1, but it does not include every feature. SAML login is available only in the licensed Business and Enterprise editions, so an organization that requires SAML must budget for a paid license. Outline's hosting docs say these licenses add functionality and guarantees. Ask Outline for the current license terms, what each edition includes and the licensing cost for your user count, and confirm whether the license must cover every environment you run.
How much admin and upgrade time does a self-hosted wiki need?
Self-hosting moves routine administration to your team: applying upgrades, monitoring the service, managing database migrations, rotating secrets and handling the identity integration. Outline's hosting docs state that it requires dev-ops experience to run in production, so the time spent is a real cost even though no license fee applies. Estimate it by listing each recurring task, its frequency and the role that performs it, then price those hours at your internal rate. Ask whether the people who will own this already run similar services.
What should backup and monitoring cost in a self-hosted wiki?
Backup and monitoring are recurring costs that come with owning the data. You need regular backups of the PostgreSQL database and of the file storage that holds attachments, tested restores, and monitoring that alerts you when the service, database or cache is unhealthy. These costs grow with the size of the content and the retention period you require. Confirm the backup frequency and retention your compliance obligations need, and ask whether your existing backup and monitoring tooling can cover Outline without new licenses.
What is the one-time migration labor for moving from Notion to Outline?
Migration is the largest one-time cost, and it is mostly labor. Outline has a Notion importer available in all editions from v0.83.0, which helps with pages, but Notion databases do not carry over as Outline documents in the same structure, so they need separate handling. Effort rises with the number of pages, the number of databases, the permission model you want to preserve, and how much content must be checked after import. Ask for a written inventory of your workspace and an estimate of cleanup work before agreeing to a scope.
What should I ask for in a quote for a self-hosted wiki?
A quote is easier to compare when it separates one-time work from recurring work. Ask for a list of one-time items: discovery, installation, identity integration, the Notion import, content verification, documentation and handover. Ask for recurring items separately: upgrades, backup testing, monitoring, support hours and infrastructure you will pay directly. DeployOpen works from a written scope with agreed deliverables and timelines, and ongoing support and upgrades are available as retainers. Ask every vendor, including Notion and Outline, to state which licenses, editions and features the quote assumes.
How a Notion-to-Outline move is carried out
The sequence below takes a team from a Notion wiki export to a self-hosted Outline instance that is running, authenticated and tested before Notion access is removed. Each step closes with a check the team can record.
Inventory what Notion holds
Before exporting, list every teamspace, top-level page, database, and attachment that people rely on, and mark which pages are wiki content and which are trackers or tables. Assign an owner to each area who will confirm the result later. The output is a written inventory that separates pages from databases so that nothing is left to discover after cutover. Confirm with the workspace owner whether any Enterprise export restrictions apply, since Notion's help center notes that Enterprise workspaces can disable exports in security settings.
Export pages from Notion
Export the page set as Markdown or HTML, working from the workspace owner's account or from a member who can see every area in the inventory. Notion's help center describes workspace-wide exports that can take a long time to produce, so schedule the export and keep the download link in a secure location. Export databases separately as CSV, because Outline's Notion importer handles pages and not the relational logic of databases. The output is a set of archives you have unzipped and listed against the inventory.
Confirm the Outline importer covers the page set
Run the Outline Notion importer against a copy of the export, not the live content, and compare the imported collections with the inventory. Check nested page hierarchy, emoji and icons, tables, embedded images, internal links between pages, and any content types your team uses heavily. Record each gap as one of three outcomes: handled by the importer, fixed by a manual edit, or moved to a different tool. The importer is available in all Outline editions from v0.83.0, so confirm your deployed version meets that floor before testing.
Stand up PostgreSQL, Redis and file storage
Provision PostgreSQL 14 or later, Redis 4 or later, and either local file storage or an S3-compatible bucket, following Outline's requirements document. Allocate at least 512MB of memory, with 1GB or more recommended, and give Outline a dedicated domain with TLS. Your infrastructure team, or DeployOpen under a written scope, can carry out this work inside your own cloud account or data center. The check that closes this step is a health check that passes against all three services from the application host, with backups configured for the database and the file store.
Configure authentication and SSO
Choose an authentication provider from those Outline supports, such as Google, Microsoft Entra, OIDC or passkeys. Outline does not offer native email and password sign-in, so plan this before anyone signs in. SAML is available only in Outline's Business and Enterprise editions, so if your identity provider requires SAML, confirm the licensing decision before the pilot begins. The check is a successful sign-in by a test account from each group that will use the wiki, with access tied to the groups your identity provider manages.
Run a pilot space with real reviewers
Import one teamspace from the export into a pilot collection and invite a small group of editors and readers to use it for normal work for a set period agreed with the project owner. Ask them to test search, editing, comments, attachments, and links from other documents. Record every broken link, missing image, or hierarchy problem in a shared list. The pilot is complete when the owner signs off on the list, and every open item has an assigned fix or an accepted limitation.
Review permissions, attachments and links
Compare access in Notion with the collection and group permissions in Outline for each area in the inventory, and remove any access that does not match the approved owner list. Check that attachments moved with their pages and that their sizes and file types are expected, and confirm that links from Outline to external systems still resolve. Notion permissions do not transfer automatically, so this review is the step that decides who can see each page after cutover. Record the result as a signed access matrix kept with the project file.
Cut over and retire Notion access
Import the final export, freeze edits in Notion for the agreed cutover window, announce the new address, and redirect users from Notion bookmarks and shared links where you can. Keep Notion read-only for a defined retention period so people can check content that did not come across. Once the owner confirms that Outline is the system of record, remove member access in Notion and archive the export files under your records policy. Databases remain a separate project that must be rebuilt in another tool, so track them as an open item until that work is done.
Questions buyers ask before switching from Notion to Outline
Does the Business Source License let us use Outline internally?
Yes, for internal use your organization can run Outline for its own staff, but the license is not open source in the OSI sense. Outline's community edition is distributed under the Business Source License 1.1, which forbids using it for a Document Service, meaning a commercial offering where third parties create their own teams and documents. Hosting Outline as a service for other companies breaches those terms and terminates the license rights. Read the Outline license file with your legal team, and confirm that your planned use fits the restriction before rollout. Each release converts to Apache 2.0 on its change date, which the license file gives as October 12, 2030 for version 1.11.0.
Does SAML single sign-on in Outline require a paid license?
Yes, SAML login is only available in Outline's licensed Business and Enterprise editions. The community edition supports sign-in through providers such as Google, Microsoft Entra, Slack, OIDC, GitLab, passkeys and email magic link, but it does not support email and password authentication natively. If your identity policy requires SAML, budget for a Business or Enterprise license and confirm current terms with Outline before you commit. If you already run an OIDC provider, check whether it can serve as the sign-in path for the community edition.
How long does a Notion export take before we can start migrating?
The duration depends on the size of your workspace and the export method you choose, and Notion does not publish a fixed time. Notion says a workspace-wide export can take up to 30 hours, and the download link expires after a set period, so plan to download promptly. Single-page or single-database exports are much faster. Workspace owners should schedule the export, confirm the archive is complete, and test a sample import before running the full migration. Check the current export process in Notion's export help because limits can change.
Do Notion databases move into Outline intact?
Usually not as live databases. Outline's Notion importer, available in all editions from v0.83.0, brings across pages and documents, but Notion databases are exported as flat files, typically CSV, and do not keep their views, properties, relations, rollups or linked views. Plan to review each database separately. Simple reference tables can be stored as Outline tables or attached CSV files, while trackers with relations usually need a different tool. If your team depends on databases, plan a separate track for them, such as a dedicated database tool.
What skills does our team need to run Outline in production?
Outline needs someone comfortable with server operations. The self-hosted stack requires PostgreSQL 14 or later, Redis 4 or later, at least 512MB of memory with 1GB or more recommended, a dedicated domain, and an authentication provider. Outline's own hosting docs say it requires dev-ops experience to run in production. Your team should be able to manage Docker or a from-source install, database backups, TLS certificates, file storage (local or S3-compatible), upgrades and monitoring. Confirm these requirements against the Outline requirements document for the release you plan to deploy.
Can our own team do the migration without outside help?
A team with platform and database experience can usually run a small pilot alone, and that is a reasonable first step. The work is an export, a test import into a staging instance, a review of what did not carry over, and a cutover plan for your users. Larger workspaces, many databases, custom permissions or SSO requirements add effort that can be hard to fit around daily work. Ask internally who owns the instance after launch, who handles upgrades, and who restores backups if something fails. Those answers decide whether you need help beyond the pilot.
When should we bring in an implementation partner for Outline?
Bring in outside help when the migration touches regulated data, SSO, backup and recovery requirements, or a deadline that your team cannot absorb. DeployOpen plans, implements, integrates, hardens, backs up, upgrades and documents self-hosted platforms in your own infrastructure, and most engagements are fixed-scope with deliverables and timelines agreed in writing before work starts. DeployOpen does not issue audit reports or certifications, so independent auditors still assess controls. Ask any partner for a written scope, the named deliverables, and what remains your responsibility after handover.
How DeployOpen helps evaluate, implement or migrate Outline
DeployOpen plans, implements, integrates, hardens, backs up and documents self-hosted open-source platforms inside your own cloud accounts, data centers or air-gapped networks. For Notion vs Outline, the work starts with a written scope that separates the wiki pages from the Notion databases and the license terms from the technical fit.
How we scope
- Inventory which Notion pages, databases and permissions will move, and which stay in Notion
- Confirm whether Outline's Business Source License 1.1 fits your intended internal use before any build starts
- Agree in writing the authentication path, since Outline needs an external sign-in provider and has no native email and password login
How we build
- Deploy Outline with PostgreSQL 14 or later and Redis 4 or later in your environment, sized to the memory guidance in Outline's requirements
- Configure the sign-in provider, file storage (local or S3-compatible) and a dedicated domain, then test access by team and collection
- Run a trial import of the Notion export through Outline's Notion importer and review how pages, attachments and links arrive
How we hand over
- Document the deployment, configuration keys, upgrade steps and the Business Source License obligations for your legal team
- Provide a record of which Notion databases were rebuilt as pages or exported as CSV, and which were left out of scope
- Deliver backup and restore runbooks covering the PostgreSQL database and file storage, tested before cutover
How we support
- Ongoing support, upgrades and testing are available as a retainer, scoped separately from the initial engagement
- Plan Outline version upgrades against release notes and the change date terms, with each update tested in a staging copy
- Agree in the quote who maintains the infrastructure, who handles user access and who owns incident response after go-live
