The Verdict
AppFlowy is Notion rebuilt for indie hackers who care about privacy and control. It's open-source, built in Rust and Flutter, and lets you self-host on your own infrastructure or use their cloud. The AI features help brainstorm and enhance writing without leaving the app. Unlike Notion's closed ecosystem, AppFlowy is a true alternative—you can fork it, extend it, own it. Perfect for teams or solopreneurs building knowledge bases, project tracking, and wikis without fear of Notion's next pricing hike or feature deprecation.
