What is OpenKnowledgebase?

An open source wiki and AI knowledge base in one. People write in a real-time Markdown wiki; AI agents read it and edit it under review, over a built-in MCP server.

Yes. Run it on your own servers with the Docker Compose setup we provide, or take EU hosting by drunomics.

Can AI agents change content unseen?

Not where review is on. Agent edits pass agent review, then human review.

How do review, trust and provenance work?

Per block, not per page. Every block records who wrote it, who reviewed it and when. A changed block waits for its sign-off while the rest of the page stays live, and AI answers cite the exact block they used.

Can AI agents edit together with my team?

Yes. An agent joins the document as a live collaborator, under a named owner's permissions. People see its edits as they happen and can comment on its work, and its changes go through the same review as a colleague's.

Which AI models can I use?

Yours — API keys or local models.

Migrating from Confluence?

We help teams move. OpenKnowledgebase is a European, open source way out of the US cloud. Talk to us about your migration.

Is all of it open source?

Yes. Every feature, MIT frontend and GPLv2+ backend. Hosting, support contracts and migration services are optional services by drunomics.

Knowledge your team and your agents can trust.

OpenKnowledgebase is a self-hosted, open source wiki and AI knowledge base. Your team writes together in real time. Your AI agents connect over MCP — and edit under review.

Agents

A knowledge base built for AI agents.

Agents are colleagues here, not scripts with a token. They read what they may read, and every change they make is reviewed before it counts.

MCP server built in

Connect Claude, Cursor or your own agents in a minute.

Agents with a name

Every edit reads "Mia via Claude". Owner's permissions, nothing more.

Reviewed before it counts

Agent review, then human review. Then it's the record.

Connect an agent

claude mcp add --transport http openkb https://kb.example.com/api/mcp

Works with Claude Code, Cursor and any MCP client, over OAuth.

Trust

AI answers you can check, down to the block.

AI knowledge management only works when the knowledge is verified. OpenKnowledgebase keeps it that way, and shows its sources.

Citations, not guesses

Every AI answer links the exact block it came from.

Provenance on every block

Who wrote it, who reviewed it, when.

Verified first

Search and retrieval prefer signed-off content. Stale blocks get flagged.

Collaboration

A self-hosted wiki your team will actually use.

A collaborative Markdown wiki with the features people leave Confluence for — on your own infrastructure.

Real-time co-editing

Presence, live cursors, offline-safe.

Inline comments

Attached to the text, not the page.

Space-based permissions

Members, read access and review policy per space.

Markdown + components

Readable anywhere. Export in one click.

Open

Your data. Your models. Your code.

Run it yourself or let us host it. Either way your data, your models and the code stay yours, under MIT and GPLv2+.

Self-hosted or EU-hosted

Run it where your data may live.

Bring your own AI

API keys or local models. Your choice.

No lock-in

Markdown content, open APIs, MIT + GPLv2+.

Technology

Built on the shoulders of giants.

No home-grown core to trust blindly. OpenKnowledgebase assembles three proven open source projects — each with a community of thousands behind it.

Drupal 11

Backend. Permissions, workflows, revisions and APIs, battle-tested on the largest sites on the web, plus the Drupal AI stack with background agents.

Nuxt 4

Frontend. Fast and decoupled, built on the Nuxt Editor for real-time editing, Nuxt Chat for the assistant, and comark for content components.

OpenSearch

Search. Hybrid keyword and semantic search at any scale, the foundation of good AI answers.

Built in collaboration with the Drupal AI initiative

OpenKnowledgebase is built in collaboration with the Drupal AI initiative: providers for every model, an agent framework with background agents, and vector and search integrations. Everything the initiative ships, OpenKnowledgebase can use.

All open source. Extend it in PHP or Vue, with skills your team already has.

All of it is open source. No open-core.

OpenKnowledgebase is a real open source knowledge base: the self-hosted edition is the whole product, under MIT and GPLv2+, developed in the open with the Drupal AI initiative. Hosting, support contracts and migration services are optional services by drunomics.
