AppFlowy
FreeOpen-source Notion alternative with local-first architecture
About AppFlowy
AppFlowy is an open-source Notion alternative built with Rust and Flutter, giving it strong performance and genuine cross-platform support including desktop and mobile. Founded in 2021, it has accumulated over 60,000 GitHub stars, making it one of the fastest-growing open-source productivity projects. The core philosophy is local-first — all data lives on your device by default with no cloud required. Optional self-hosted sync lets teams share data without a third-party cloud. Features include rich documents, Kanban boards with multi-select fields, grid database views, calendar views, and a growing plugin system. The Rust backend provides efficient local data processing while Flutter enables true cross-platform deployment. Mobile apps for iOS and Android are available. AppFlowy positions itself as a Notion replacement for users who prioritize data ownership over feature completeness. The feature gap with Notion in terms of integration breadth and polished UX is real but narrows with each release. For privacy-conscious individuals and teams willing to trade some polish for full data sovereignty, AppFlowy is the most credible Notion alternative in the open-source space. Active development and a welcoming community make it a solid long-term bet for those committed to self-hosted productivity.

Who Is This For?
Hands-on tested May 2026
Signup Experience
Desktop app download requires no account for local use. Cloud sync requires an AppFlowy Cloud account via email signup. The local-first approach means you can use the full app offline immediately after install.
For Home Users
A capable Notion alternative for anyone wanting offline-first notes and databases. The block editor and database views cover the core Notion workflow. Noticeably less polished than Notion but improving steadily with each release.
For Business Users
Cloud collaboration features are functional but still maturing compared to Notion. The open-source nature and self-hosting option make it attractive for teams with data residency requirements. Best suited for technical teams willing to accept some rough edges in exchange for data ownership.
Our Verdict
AppFlowy is the most promising open-source Notion alternative. The Rust backend makes it fast and the Flutter frontend provides cross-platform support. Still early compared to Notion but developing rapidly. If data ownership matters more than feature completeness, AppFlowy delivers.
