The stack is PostgreSQL for storage and Redis for real-time collaboration and background jobs. On top of that: spaces, nested pages, granular permissions, page history, Draw.io\/Excalidraw\/Mermaid diagrams, and S3-compatible storage for attachments. Built-in importers pull existing content over from Confluence or Notion exports, so switching doesn&#8217;t mean starting from a blank wiki.<\/p>\n\n\n\n<p>It&#8217;s newer than Outline and moving fast, which cuts both ways \u2014 frequent improvements and an active issue tracker, but a shorter production track record than a project that&#8217;s been running in enterprise environments for years. Enterprise SSO, advanced permissions, and AI features sit behind a paid Business\/Enterprise tier if you need them later, but the free AGPL edition already covers what most small-to-medium teams need. It&#8217;s the best fit for teams who want a clean, self-hosted, open source confluence alternative without an SSO dependency on day one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Outline Wiki: Mature, SSO-Required<\/h2>\n\n\n\n<p>Outline wiki has around 38,000 GitHub stars and a much longer production history than Docmost. It ships under the Business Source License (BSL 1.1) rather than a traditional open-source license \u2014 self-hosting for your own team is fully permitted and free, but the license restricts offering Outline as a competing hosted service, and it only converts to a permissive license after a set date per release. That distinction matters most for organizations with open-source-first procurement policies (government agencies, some enterprises); everyone else can mostly treat it as a detail rather than a blocker.<\/p>\n\n\n\n<p>The editor is polished, the API is mature, and the integration ecosystem (Slack, Figma, Loom, and 20+ others) is deep \u2014 this is the project&#8217;s real strength, and years of production use show in the details. The catch that trips people up on day one: Outline has no built-in email\/password login at all. Every sign-in goes through an external identity provider \u2014 Google, Slack, or a generic OIDC\/SAML service like Keycloak or Authentik \u2014 and it also expects S3-compatible storage configured before file uploads work. That&#8217;s real setup complexity for a small team that doesn&#8217;t already run an identity provider, even though the payoff is a genuinely refined product once it&#8217;s running. Outline also offers a commercial hosted cloud version for teams that decide self-hosting isn&#8217;t worth the operational overhead after all.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Notion: No Self-Hosting, Full SaaS<\/h2>\n\n\n\n<p>Notion has no self-hosted option, and that&#8217;s the whole story for teams that need data on their own infrastructure \u2014 it&#8217;s ruled out immediately, regardless of price or features. It remains strong for personal use and small teams that don&#8217;t mind data living on Notion&#8217;s servers, with a flexible database-and-page model that neither Docmost nor Outline tries to replicate. Pricing runs on a per-seat SaaS model that scales with headcount, which is exactly the ongoing cost both Docmost and Outline let you sidestep in exchange for running your own infrastructure.<\/p>\n\n\n\n<p>For EU\/GDPR teams or anyone who needs on-prem or self-hosted deployment, the two credible self-hosted Notion alternatives are Docmost and Outline \u2014 Notion itself isn&#8217;t in the running. The same outline vs notion tension that shows up elsewhere (polished all-purpose workspace vs. structured, ownable wiki) is really a proxy for this bigger question: does your data need to stay on infrastructure you control, or not? Once the answer is yes, Notion drops out of consideration entirely and the comparison becomes Docmost vs Outline.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Which Self-Hosted Wiki Should You Choose?<\/h2>\n\n\n\n<p>Once Notion is out of the running for infrastructure reasons, the practical docmost vs notion question rarely comes up on its own \u2014 it collapses into Docmost vs Outline.

Docmost&#8217;s importer reads Confluence and Notion exports directly, and Outline&#8217;s export\/import tooling does the same in the other direction, so neither choice means retyping a wiki from scratch. The bigger cost is almost always the identity-provider setup for Outline, not the content migration itself \u2014 budget time for that step specifically if you go that route and don&#8217;t already run SSO somewhere in your stack.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Running Docmost on Contabo with Docker: Recommended Setup<\/h2>\n\n\n\n<p>For a small-to-medium team, a Contabo Cloud VPS 6 (6 vCores, 12 GB RAM, 200 GB storage, \u20ac7.00\/month) is the sweet spot for a Docmost docker deployment \u2014 enough RAM to run the app, PostgreSQL, and Redis comfortably with headroom for concurrent editors, at Contabo&#8217;s RAM-per-Euro Core-line pricing. Point file attachments at Contabo Object Storage instead of local disk so uploads survive a server rebuild and don&#8217;t eat into the VPS&#8217;s own disk quota.

Docmost is better if you want a genuinely open-source license, built-in email\/password login, and a lighter setup with no identity provider required \u2014 you can have a small team writing pages within minutes of deploying the Docker Compose stack. Outline is better if you already run SSO, want the most mature and polished editor available, and don&#8217;t mind the BSL license terms. Neither is universally superior \u2014 they suit different starting points, and the honest answer is &#8216;it depends what infrastructure you already have.&#8217;<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1783935719711\"><strong class=\"schema-faq-question\">Is There a Self-Hosted Notion Alternative?<\/strong> <p class=\"schema-faq-answer\">Yes \u2014 Docmost and Outline are both credible self-hosted Notion alternatives, though neither replicates Notion&#8217;s database-and-formula workspace exactly; both are wikis first, not all-purpose workspaces. Both give you a real-time collaborative editor and full data ownership on infrastructure you control; Docmost is the lighter, more open-source pick, while Outline offers a more Notion-like editing feel at the cost of requiring external SSO before anyone can sign in.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1783935732072\"><strong class=\"schema-faq-question\">Does Outline Wiki Require SSO?<\/strong> <p class=\"schema-faq-answer\">Yes, effectively. Outline has no built-in email\/password login \u2014 every user signs in through Google, Slack, or a generic OIDC\/SAML provider such as Keycloak or Authentik. If your team doesn&#8217;t already run one of these, you&#8217;ll need to stand up an identity provider before anyone can use Outline at all, which is the main setup cost that Docmost avoids by shipping working email\/password auth out of the box.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1783935743608\"><strong class=\"schema-faq-question\">What is the best self-hosted Confluence alternative?<\/strong> <p class=\"schema-faq-answer\">Among self-hosted confluence alternatives, Docmost and Outline are the two strongest contenders in 2026. Docmost is the better fit for teams that want a real open-source license and minimal setup; Outline is the better fit for larger organizations that already run SSO and want the most mature, feature-complete editor available. Both replace Confluence&#8217;s per-seat licensing with infrastructure you control, and both ship importers that make migrating existing Confluence content straightforward.<\/p> <\/div> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>In short.
