AFFiNE is an open source alternative to Miro. Privacy-first knowledge base combining docs, whiteboard canvas, and databases in one self-hosted workspace. MIT licensed, 71.4k GitHub stars, hosted version available, self-host with Docker, and last released 2026-07-23.
Privacy-first knowledge base combining docs, whiteboard canvas, and databases in one self-hosted workspace.
Teams that want an infinite canvas whiteboard alongside structured docs and databases in a single self-hosted workspace, prioritizing local-first data ownership.
You need a standalone whiteboard tool without the Notion-style knowledge base overhead, or your team requires modifying and redistributing the backend server code.
The backend server is NOT open source. packages/backend/server/ is under the AFFiNE Enterprise Edition license: production use requires a paid subscription; modifying or redistributing that code without commercial authorization is prohibited. The editor, desktop app, and BlockSuite whiteboard engine are MIT and free. Free self-hosted tier caps workspaces at 3 members and 10 GB cloud storage.
