AFFiNE
Open-source local-first workspace combining docs, whiteboards, and databases with AI writing, used as a Notion alternative with 45k+ GitHub stars.
AFFiNE is an open-source, local-first knowledge management platform that unifies block-based document editing, infinite canvas whiteboards, and structured database views in a single application, offering a privacy-respecting alternative to Notion. Its AI assistant can generate, summarize, translate, and rewrite content within documents and on whiteboard canvases. AFFiNE stores data locally on the device by default with optional encrypted cloud sync, giving users full ownership of their notes and knowledge. The project has 45,000+ GitHub stars and a self-hosting option via Docker for teams who want complete data sovereignty. A cloud-hosted version with a free tier launched in 2023, making it accessible to users who prefer managed hosting without technical setup.
