Just wanted to share some open source options that allow for self-hosting (but in order to make money, have paid feature restrictions) in light of Affine.Pro launching it’s first fully fledged version today.

Affine.Pro - MPL Licensed - their unique selling point is the ability to switch between text and whiteboard view for the same page: https://github.com/toeverything/AFFiNE

Siyuan - GPL Licensed - Probably the most advanced personal note/knowledge management app on the market - blows Joplin, Obsidian, Logseq out of the water: https://github.com/siyuan-note/siyuan

AppFlowy - GPL Licensed - their unique selling point is that they’re farther along than SiYuan or Affine on their database table functionality. Both Siyuan and Affine have database tables for project management but Appflowy’s solution is solid. https://github.com/AppFlowy-IO/AppFlowy
