Best Confluence Alternatives in 2026: Team Wikis, Knowledge Bases and Docs Tools

Docmost, Outline and Notion are the Confluence alternatives to try first for an internal wiki. Docmost is a self-hosted, Confluence-style wiki that can import Confluence content, Outline is a quick hosted or self-run knowledge base, and Notion puts docs and projects in one workspace. For public product docs or a help center, GitBook and Document360 are the better fit.

Confluence is used for two different jobs: internal wikis where staff write and search company knowledge, and customer-facing documentation. This guide separates them. The first eight picks are internal wiki and knowledge-base tools, the last three are for published docs, and a short section covers free wiki software.

Why people look for Confluence alternatives

Confluence is Atlassian's team workspace for writing, organizing and sharing documentation and knowledge, with AI help for drafting, summarizing and finding answers. People compare it with other tools for a handful of concrete reasons.

• Closed source, no self-hosting in Enlisted's data. Enlisted lists Confluence as proprietary and hosted, so wikis that must live on your own infrastructure need a different tool.
• Per-user pricing. Enlisted lists a free sign-up for small teams, then paid plans charged per user, with enterprise pricing unpublished.
• Jira coupling. The vendor stresses tight integration with Jira. That helps teams that use both and gives less to teams that do not.
• Internal first. Confluence is organized around pages, spaces and templates for teams. Customer-facing documentation sites and help centers have dedicated tools with reader analytics, Git workflows and API reference pages.
• A big template library. Templates are grouped by team, from product management to HR. Smaller groups may only want a plain wiki.

How we picked

Every tool here lets a team write, organize and search shared documentation, which is Confluence's core job. Enlisted's data sorted them into internal wikis and public documentation tools. Open-source wikis were screened for a readable licence and recent commits, and a project whose repository warns it is not for production is flagged. Hosted entries are described by their published pricing model and free plan. The descriptions rest on catalogue entries and vendor sites, and no first-hand testing is claimed. See how Enlisted ranks tools.

1. Docmost: best self-hosted wiki that imports from Confluence

Docmost is an open-source collaborative wiki and documentation tool, positioned as an alternative to Confluence and Notion with a focus on secure, on-premises use. Its site lists real-time editing with live cursors, team spaces, role-based access control, page verification workflows and diagrams through Draw.io, Excalidraw and Mermaid, and says it can import from Confluence, Notion, HTML and Markdown files.

Enlisted also lists comments, page history, full-text search, file attachments, and embeds for tools such as Airtable, Loom and Miro. Docmost is released under AGPL-3.0. The self-managed Community edition is free, a Business edition is charged per seat, and Enterprise is quoted. The site references separate standard and enterprise licences, so confirm which edition includes the controls you need, such as single sign-on.

• Best for: teams replacing Confluence that want an on-premises wiki with the same spaces-and-pages feel.
• Watch out for: paid editions add features, and you run upgrades and backups if you self-host. AGPL-3.0 has network copyleft terms if you modify it and offer it to others.

2. Outline: best fast knowledge base, hosted or self-run

Outline is a collaborative team knowledge base and wiki with real-time editing and Markdown compatibility, built with React and Node.js. Its site describes search and question answering, slash commands, integrations including Slack, an open API, and permissions with user groups and guest sharing.

Documents are organized into collections, so a growing team can find what it has written down. You can use the hosted service at getoutline.com, which has a trial and charges by team size, or run the published container images on your own infrastructure. Enlisted lists its licence as Other, so read the repository's terms before self-hosting commercially.

• Best for: teams that want a focused, quick-to-write wiki, hosted or on their own servers.
• Watch out for: the hosted service has no free plan in Enlisted's data, and the licence is not a standard open-source one.

3. Notion: best when docs, wiki and projects share a workspace

Notion is an AI-enabled workspace for notes, docs, wikis and projects, with agents, meeting notes and search across connected apps. Where Confluence is a wiki that links to Jira for tasks, Notion keeps knowledge bases, docs and project tracking in one product.

It has a free plan for individuals, paid plans charged per member, and enterprise pricing through sales. Notion is closed source and hosted only. The Notion alternatives guide covers it in depth.

• Best for: startups and small teams that want a flexible wiki alongside projects and notes.
• Watch out for: flexibility means someone must curate the structure, and there is no self-hosted edition.

4. BookStack: best simple self-hosted wiki for non-technical writers

BookStack is a self-hosted wiki and documentation platform built with PHP and Laravel, organizing content into shelves, books, chapters and pages. Its aim is an intuitive out-of-the-box experience where only basic word-processing skills are needed to write, so non-technical colleagues can contribute.

It is MIT-licensed, upgrades are meant to stay stable and easy, and there is a demo instance and documentation. Enlisted lists no vendor-hosted version.

• Best for: companies, schools and teams that want a plain, structured internal wiki on their own server.
• Watch out for: content follows a shelves, books, chapters and pages structure, and the project says it is not meant as a general extensible platform for unrelated uses.

5. Slite: best hosted knowledge base with verified pages

Slite is a hosted knowledge base that combines documents, channels and AI-powered search. Documents can carry a verified status, knowledge base audits help catch outdated pages, and an AI agent answers questions from the content.

The vendor says customers can migrate from tools including Notion and Confluence. There is a trial but no free plan, and paid plans are charged per user. Slite is closed source and hosted only.

• Best for: small and mid-size companies that want a maintained handbook, policies and onboarding docs.
• Watch out for: no free plan and no self-hosting, and it is a knowledge base rather than a place for project tracking.

6. Nuclino: best lightweight wiki for small teams

Nuclino is a lightweight team wiki that brings docs, projects and knowledge into one workspace, with a clutter-free editor, boards, graph views, instant search and hotkeys. The vendor positions it as a way to replace several collaboration tools with one.

It has a free plan limited by the number of items, paid per-user plans, and a trial on Starter. Closed source and hosted only.

• Best for: small teams that want fast, simple notes and handbooks.
• Watch out for: the free plan is capped on content, and it is lighter than Confluence on templates and enterprise controls.

7. XWiki: best Java platform for large intranets and wiki applications

XWiki is a generic Java wiki platform that provides runtime services for applications built on top of it. It is licensed under LGPL-2.1, with separate guides for developers, administrators and users, a public API reference and release notes.

Enlisted lists company knowledge bases, intranets and structured applications built on a wiki as use cases. It is a platform rather than a polished out-of-the-box wiki, so it suits organizations with Java skills.

• Best for: larger organizations that want an extensible, self-hosted wiki and intranet platform.
• Watch out for: more setup and administration than BookStack or Docmost, and there is no vendor-hosted option in Enlisted's data.

8. Wiki.js: best Markdown wiki with Git sync

Wiki.js is a Node.js wiki with a Vue front end, released under AGPL-3.0. Its site lists a Markdown editor with live preview, a visual builder, HTML pages, Git sync with GitHub and GitLab, and permissions through user groups and page rules, with LDAP and SAML authentication.

One caveat: Enlisted's listing tracks the 3.0 beta repository, whose README says it is not for production use. The site names a stable 2.x release as the current production line, so install that one.

• Best for: technical teams that want documentation in Markdown, synced with Git.
• Watch out for: the 3.0 beta is not production-ready, so stick with the stable 2.x line, and you run it yourself.

9. GitBook: best for public product docs and docs-as-code

GitBook is a documentation platform for product docs, help centers and internal knowledge. It combines a visual editor with docs-as-code support, so teams can write in the app or sync with Git repositories, and its AI features flag gaps and outdated content.

The site also lists search, an Ask feature for questions, an API and an MCP server. There is a free plan for individuals, and paid plans are priced per site plus extra users, with a trial. It is closed source and hosted only.

• Best for: software companies publishing product and API documentation.
• Watch out for: paid plans are priced per site, so cost scales with how many docs sites you run.

10. Document360: best for help centers with review workflows

Document360 is hosted knowledge base software for product documentation, internal wikis and customer self-service. Editors work in a portal with a custom workflow builder for review and approval, and readers use a public or private site with AI search and a chatbot.

It imports from PDF and Word files and adds analytics, SSO and SCIM, and an API. Enlisted lists no flat prices: Document360 quotes a custom plan by workspaces, languages, team accounts, SSO needs and AI usage.

• Best for: support and documentation teams that need review workflows and reader analytics for a help center.
• Watch out for: no published pricing and no free plan, so you have to request a quote.

11. Mintlify: best for developer docs with API reference pages

Mintlify is a hosted documentation platform for software products. Teams write docs in files and publish a site with guides and API reference pages, AI-powered search, and an llms.txt file so AI agents can read the docs.

It has a free Starter plan, a paid Pro plan with a trial, and enterprise by contact. Mintlify is closed source and hosted only.

• Best for: developer-facing companies that publish API and product documentation.
• Watch out for: it is built for public docs, not as an internal wiki for HR policies or meeting notes.

Other options worth a look

• More hosted wikis: Slab is an internal wiki with Topics and search across connected tools, Tettra answers team questions from your docs through a Slack bot, and Guru focuses on verified company knowledge.
• More help-center tools: Helpjuice and HelpDocs publish customer help centers, Archbee and ClickHelp serve product and technical documentation, and ReadMe builds API developer hubs. See the customer support category too.
• Open-source workspaces: AppFlowy is a Notion-style workspace with a self-hosting option, and La Suite Docs is an MIT-licensed collaborative editor with subpages and access control.
• Real-time notes: HedgeDoc and Etherpad are self-hosted collaborative editors, better for meeting notes than structured wikis. For personal knowledge bases, see the best note-taking apps.

What is the best free wiki software?

Free wiki software comes in two kinds: self-hosted open-source wikis with no licence fee, and hosted tools with a limited free tier.

• BookStack is MIT-licensed and organizes content into books and chapters.
• DokuWiki is a PHP wiki under GPL-2.0, and Enlisted describes it as storing pages as plain text files instead of requiring a separate database.
• MediaWiki powers Wikipedia, is extensible with many extensions and is available in many languages.
• Otter Wiki is a minimal Python wiki under MIT that stores Markdown pages in a Git repository and installs through Docker Compose.
• Gollum is an MIT-licensed wiki built on Git that stays compatible with GitHub and GitLab wikis, though Enlisted's data shows less recent activity than the others here.
• Docmost Community and Wiki.js are free to self-host, as covered above.
• Hosted free tiers: Notion is free for individuals, Nuclino has a free plan with limits, and Confluence itself has a free sign-up for small teams. GitBook and Mintlify have free plans for documentation.

You can browse more on the documentation category page, and the free Microsoft Office alternatives guide covers word processors if what you need is documents, not a wiki.

Internal wiki or public docs: which do you need?

The two jobs have different requirements, which is why no single tool tops every list.

Which Confluence alternative should you choose?

For a complete list, see all open-source Confluence alternatives on Enlisted, and the matching pages for GitBook, Slite and Document360. If you use Confluence alongside Jira, the Jira alternatives guide covers the other half of that pairing.

Before you migrate off Confluence

Decide first what the wiki is for, since an internal handbook and a public help center want different tools. Then audit your spaces: archive pages nobody has opened for years rather than moving them, and note which pages depend on Jira links or other Atlassian features, because those will not carry over. Docmost lists direct imports from Confluence, and Slite says customers can migrate from it. For content that cannot be imported, Pandoc is a command-line converter that reads formats including HTML and Word documents and writes Markdown. Move one team's space first as a trial run, and for self-hosted tools agree who owns upgrades and backups.
