Docmost

Docmost is the AGPL-3.0 wiki and collaborative documentation platform XDA covered as a Notion swap this month, and the coverage was earned. Real-time collaborative editing via CRDT, spaces with nested pages, a Tiptap-based editor with slash commands and Excalidraw diagrams, and built-in Confluence and Notion importers. All of it self-hosted with Postgres and Redis via Docker Compose. The gap Docmost leaves is scale: it is designed for teams up to a few hundred, not enterprise, and it does not ship with public API stability yet.

We self-hosted seven Docmost alternatives on desktop that share the DNA: real-time collaboration, self-hosting, and full data ownership. The list runs from direct Confluence swaps to Notion-adjacent workspaces and single-user knowledge vaults.

Quick comparison

The signal on r/selfhosted, the Docmost GitHub Discussions, and the XDA and Contabo coverage this month:

Each pick below addresses one or more of these gaps. The first three are direct Notion or Confluence swaps. The middle two are structured wikis. The last two go single-user or local-first.

The 7 best Docmost alternatives

Outline, best team wiki with polish

Outline is the polished team wiki that competes with Confluence Cloud head-on. Slack integration is native (comment threads sync to channels), the editor is fast and MDX-adjacent, and permissions handle enterprise cases (groups, guests, viewer-only spaces). The catch is licensing: Outline is BSL 1.1 (source-available), not open source, and requires an external OIDC or SAML provider to self-host at scale.

For Docmost users who need a more polished editor and Slack integration and can accept BSL 1.1 licensing, Outline is the pick.

Where it falls short: BSL 1.1 is not OSI-approved open source. Requires an external identity provider (Google, GitHub, SAML). Self-hosted deployment is more complex than Docmost’s Docker Compose.

Pricing:

Switching from Docmost: Set up OIDC via Google Workspace or Authelia first. Outline’s auth is not usable without an external provider.

Download: Outline on the official site

Bottom line: Pick Outline when polish and Slack integration matter more than a strict open-source license.

AppFlowy, best Notion-shaped local-first workspace

AppFlowy is the closest UI-level Notion swap in the open-source world. Blocks, tables, boards, and calendar views all match the Notion mental model, the native desktop app runs offline-first on Windows, macOS and Linux, and the cross-device sync layer (paid at scale) closes the gap Notion opened. AppFlowy Cloud is available as a self-hosted option and the license is AGPL-3.0.

For Docmost users who want a workspace that looks and feels like Notion without giving up self-hosting, AppFlowy is the pick.

Where it falls short: Desktop-first, so browser access is limited. Team collaboration is still less mature than Docmost’s CRDT-based editor. Sync setup for self-hosting requires more Postgres knowledge than Docmost.

Pricing:

Switching from Docmost: Start with the local desktop app. Cloud sync only matters once your team is bigger than three.

Download: AppFlowy on the official site

Bottom line: Pick AppFlowy when the Notion mental model is what you actually want and desktop-first is fine.

Affine, best Notion plus Miro plus Figma

Affine by Toeverything folds documents, whiteboards and databases into one workspace. Edgeless mode is the whiteboard layer (drop docs into a canvas), the editor is a Tiptap-adjacent block system, and the database views (table, kanban, gallery) sit on the same primitives as the documents. Affine is MPL-2.0 open source and ships desktop apps on Windows, macOS and Linux plus a self-hosted cloud option.

For Docmost users who want a whiteboard next to the wiki, Affine is the pick.

Where it falls short: The whiteboard layer adds complexity most wiki users do not need. Self-hosted Affine Cloud is newer and less battle-tested than Docmost. Real-time collaboration in Edgeless mode has more sync edge cases.

Pricing:

Switching from Docmost: Start in doc-only mode. Enable Edgeless once you have a real reason to use a whiteboard.

Download: Affine on the official site

Bottom line: Pick Affine when you want documents plus whiteboards plus databases in one self-hosted stack.

BookStack, best small team knowledge base

BookStack is the MIT-licensed PHP-based wiki that fits non-technical teams. The books, chapters, pages structure maps to how most people already think about documentation, the editor is a friendly TinyMCE rich-text mode with an optional Markdown mode, and the deployment is a straightforward LAMP stack (or Docker) with no external dependencies. Community activity is high, and the plugin ecosystem covers most of the common asks.

For Docmost users on a small team who want the simplest possible wiki with no learning curve, BookStack is the pick.

Where it falls short: No real-time collaborative editing. PHP stack is less trendy than Node.js. Editor is dated next to Tiptap-based options.

Pricing:

Switching from Docmost: Set up your book structure first. BookStack rewards planning the hierarchy up front rather than adding pages ad hoc.

Download: BookStack on the official site

Bottom line: Pick BookStack when your team is small and simplicity is worth more than real-time collaboration.

Wiki.js, best developer-focused wiki with Git backing

Wiki.js is the AGPL-3.0 wiki built by developers for developers. Git storage backend means every page write becomes a commit, Markdown-first authoring with syntax highlighting for code blocks, and a plugin architecture that covers OAuth, LDAP, S3-backed uploads and more. The 3.0 branch is a full rewrite currently in beta, so most production installs still run 2.x.

For Docmost users on engineering teams who want Git-backed pages, Wiki.js is the pick.

Where it falls short: Real-time collaboration is not on the roadmap. The 2.x codebase is showing its age. 3.0 beta is not production-ready.

Pricing:

Switching from Docmost: Point the storage backend at a private Git repository. It is the whole reason to run Wiki.js.

Download: Wiki.js on the official site

Bottom line: Pick Wiki.js when Git-backed pages matter and your team is technical.

Trilium Notes, best single-user knowledge vault

Trilium Notes is the AGPL-3.0 single-user hierarchical note tool that scales from a scratchpad to a full second brain. Note attributes let you tag pages with typed metadata, the scripting API lets you build small automations inside the tool, and the sync server is a small self-hosted process you can run on a Raspberry Pi. Cloning notes across the hierarchy is the killer feature: a single note can appear in multiple trees without duplicating content.

For Docmost users who want a single-user vault sitting next to the team wiki, Trilium is the pick.

Where it falls short: Single-user by design (no multi-user auth in the local app; sync server pairs one client at a time). UI is dense out of the box. Web view is a compromise next to the desktop app.

Pricing:

Switching from Docmost: Run Trilium alongside Docmost, not instead of. Docmost is the team knowledge base; Trilium is the personal one.

Download: Trilium Notes on GitHub

Bottom line: Pick Trilium when a single-user hierarchical vault is what you actually want.

Anytype, best local-first Notion swap with encryption

Anytype is the local-first, end-to-end encrypted Notion alternative. Every object (page, task, database row) is a typed record, sync uses a P2P layer across your own devices, and the mobile apps close the loop Docmost’s web-only interface leaves open. The Any Source License is source-available with commercial-use restrictions; it is not OSI-approved open source but the model is transparent.

For Docmost users who want end-to-end encryption and mobile parity, Anytype is the pick.

Where it falls short: Not OSI open source. Team collaboration is newer and less mature. Learning curve on the object model is steep.

Pricing:

Switching from Docmost: Spend an hour on the object-model docs before importing anything. Anytype makes sense once the primitives click; it is confusing until then.

Download: Anytype on the official site

Bottom line: Pick Anytype when end-to-end encryption and cross-device sync matter more than team collaboration polish.

How to pick the right one

If you need the most polished team wiki and can accept BSL 1.1 licensing, install Outline. It is the closest Confluence swap on the list.

If you want the Notion mental model in an open-source workspace, AppFlowy is the pick. If you want documents plus whiteboards plus databases in one stack, Affine is the choice.

If your team is small and simplicity is more important than real-time editing, BookStack is the fastest to deploy. If your team is technical and Git-backed pages matter, Wiki.js is the natural pick.

If you want a single-user hierarchical vault next to the team wiki, run Trilium Notes alongside Docmost. If end-to-end encryption and mobile parity are the priorities, Anytype is the pick.

Stay with Docmost when real-time collaborative editing plus a simple Postgres-and-Redis Docker Compose deploy is the main draw. It hits the middle of the market cleanly, and none of these alternatives beat it on that specific axis.

FAQ

Is Docmost fully open source?

Yes. Docmost is licensed under AGPL-3.0. The self-hosted community edition is functionally complete; the hosted cloud version is optional.

Does Docmost support Notion imports?

Yes. Docmost ships with importers for Confluence and Notion exports. The Confluence importer handles space structures; the Notion importer handles page trees and databases in most common cases.

What is the cheapest Docmost alternative to self-host?

BookStack and Wiki.js both run on modest VPS hardware (2 GB RAM, 1 vCPU) and are fully free. Trilium Notes runs on a Raspberry Pi. All three sit under $10 per month in hosting costs for a small team.

Which Docmost alternative has the best real-time collaboration?

AppFlowy Cloud and Affine both ship real-time editing today, though the underlying CRDT layers are newer than Docmost’s. Outline has real-time editing but requires an external identity provider.

Can teams self-host a Notion alternative at scale?

Yes. Docmost, Outline, AppFlowy Cloud and Wiki.js all scale to hundreds of users. Postgres or MySQL sizing is the main constraint; the app tiers are lightweight next to a modern Slack workspace.
