R.I.P.Open-source alternatives to Notion
23 projects replace Notion, the all-in-one workspace. 18 shipped code in the last 30 days.
Notion bills per member, and its AI features sit in the higher plans. Pages live on Notion's servers, and the export is lossy: databases come out as CSV files and links between pages often break. Teams that outgrow it usually want their notes on their own disk or server.
AppFlowy and AFFiNE are the closest copies, with blocks, databases and offline apps. Anytype syncs peer to peer with end-to-end encryption, which suits private notes more than a shared company wiki. If Notion was mostly your team wiki, Outline or Docmost will feel simpler and are easier to run.

What you give up by leaving Notion
The honest part. Free and open usually costs something else.
- Fewer integrations Notion connects to hundreds of apps out of the box, while most alternatives offer a handful plus an API.
- Smaller template gallery Notion's community template library is huge, and no open-source project comes close to its size.
- You run the server Self-hosting means you handle backups, updates and uptime, unless you pay for the project's own cloud plan.
- AI is bring-your-own Built-in AI often means connecting your own model or API key instead of a ready subscription.
