Affine
Notion meets Miro in one local-first workspace — write docs, draw diagrams, and organize knowledge
Editor's Take
Affine is the most ambitious open source productivity tool I've seen — it doesn't just clone Notion or Miro, it combines both. You can write a structured doc with linked pages and databases, then instantly switch to a canvas mode and start diagramming or mind-mapping the same content. The local-first architecture is a genuine differentiator: your data lives on your machine first, not in someone else's cloud. This matters for anyone who's worried about Notion changing pricing or going offline. The interface is polished, the performance is snappy, and the collaboration features work well. The trade-off is that some advanced Notion features like complex database relations aren't fully matched yet.
Good first choice if you want a practical tool without spending the afternoon reading developer docs.

Why It Stands Out
- 1Switch seamlessly between document editing and whiteboard canvas modes
- 2Local-first architecture keeps your data on your device with optional cloud sync
- 3Open source with no vendor lock-in — export everything at any time
Best Use Cases
Replace Notion with open source
Write and organize docs with databases, tables, and linked pages — all open source
Brainstorm and document in one place
Switch from whiteboard-style diagramming to structured documentation without changing apps
Keep knowledge private and portable
Store everything locally by default, with optional sync — no vendor can hold your data hostage
Plain-English Buying Guide
Affine is a good candidate for individuals, students, teams, developers who want an open source option in the productivity category. The key question is not whether the repository is popular. The better question is whether it removes a real friction point from your day: replacing a paid SaaS tool, keeping more data under your control, speeding up a repeated task, or giving a team a workflow they can inspect and adapt.
Affine is most useful when your goal matches one of its real use cases rather than when you are simply browsing popular repositories. Start by checking whether "replace notion with open source" sounds like your situation. If it does, read the install guide, try the smallest possible setup, and only then decide whether to bring it into a personal workflow or team stack. The project is tagged around knowledge-base, docs, whiteboard, notion-alternative, which gives you a quick sense of the ecosystem it belongs to. It can also fit "brainstorm and document in one place", but that second path may require a different setup or expectation.
Before You Install
Affine is one of the easier projects in this category to try first. You should still check the official installation page, but the expected path is closer to downloading an app, running a simple command, or following a guided setup than maintaining a complex server.
Check the MIT license, the TypeScript ecosystem, and the latest activity on GitHub before using it for important work.
When to Skip It
Skip it for now if your current tool already solves the same problem well. Open source is most valuable when it gives you privacy, flexibility, cost savings, or a workflow improvement you cannot get from your existing setup.
