Open source alternatives to Notion

All-in-one workspace combining docs, databases, and project management. · Notion Labs

Pricing: Free for personal use; paid plans from $10/user/mo

Notion's 'docs + databases + project management' bundle is the closest thing to a category-of-one in the productivity space. Open-source alternatives split into two camps: docs-and-wiki (Outline, BookStack, Wiki.js) and full workspace clones (AppFlowy, Affine). Pick Outline if you want 'Notion docs' without the databases. Pick AppFlowy if you want a full Notion replacement including the database model.
