# Confluence alternatives for AI agents

3 alternatives to Confluence. 3 have an interface an agent can drive. 2 are open source.

Page: alternatives/confluence.html

## BookStack

Opinionated documentation wiki (shelves, books, chapters, pages) with .env config and a token REST API.

- Listing: apps/bookstackapp--bookstack.html
- JSON: apps/bookstackapp--bookstack.json
- License: MIT
- Agent interface: API, from the builder
- Reach: 9 of 10 jobs
- Last activity: 2026-09-02
- Effort: config-only
- Agent cannot reach: Diagrams (diagrams.net drawings) and WYSIWYG editing
- Use it when: you need an internal manual or client documentation site with roles and SSO, without a per-seat price
- Use it when: you want an agent to write and file runbooks into books and chapters over a token API
- Gotcha: Primary development moved to codeberg.org/bookstack/bookstack; GitHub is a mirror, and issues go to Codeberg
- Gotcha: Needs PHP and MySQL/MariaDB; the docker-compose.yml in the repo is for development, and Docker images are community-maintained (linuxserver.io, solidnerd)
- Gotcha: API tokens need the Access System API permission; default rate limit 180 requests per minute

## OpenKnowledge

WYSIWYG markdown knowledge-base editor that ships a 21-tool MCP server and skills for coding agents.

- Listing: apps/inkeep--open-knowledge.html
- JSON: apps/inkeep--open-knowledge.json
- License: GPL-3.0
- Agent interface: MCP server, from the builder
- Reach: 8 of 10 jobs
- Last activity: 2026-09-03
- Effort: config-only
- Agent cannot reach: In-app AI chat and slides
- Use it when: you keep specs and a team wiki as markdown in git and want agents to search, lint, and edit them with history
- Use it when: you want an Obsidian-like editor that installs its own MCP and skills into Claude Code and Codex
- Gotcha: GPL-3.0
- Gotcha: Semantic search sends content to the embeddings provider; off by default
- Gotcha: Every MCP call takes a cwd; a globally registered server needs it unless the client advertises one root
- Gotcha: Web app needs Node.js 24+ and git

## Outline

Team knowledge base with a documented REST API and an in-repo MCP route, self-hostable under BUSL.

- Listing: apps/outline--outline.html
- JSON: apps/outline--outline.json
- License: BUSL-1.1
- Agent interface: MCP server, from the builder
- Reach: 7 of 10 jobs
- Last activity: 2026-09-03
- Effort: config-only
- Agent cannot reach: Slack, GitHub, Linear, Notion integrations; AI question answering
- Use it when: your team needs a wiki with SSO and you want an agent to draft and file docs into the right collection
- Use it when: you want Notion-style docs on your own Postgres without a per-seat bill
- Gotcha: BUSL-1.1 Additional Use Grant forbids offering Outline as a Document Service to third parties; converts to Apache-2.0 on 2030-09-01
- Gotcha: Requires an external identity provider; there is no local email-and-password login
- Gotcha: Maintainers reject AI-generated pull requests (README)
- Gotcha: MCP tools are filtered by OAuth scopes; the client needs an OAuth token, not a plain API key
