AppFlowy – An Open-Source Notion Alternative Built with Flutter
Hey I recently stumbled upon AppFlowy (https://github.com/AppFlowy-IO/AppFlowy), an open-source project that caught my attention. It's essentially a Notion-like workspace, but with a twist: Built with Flutter (front-end) and Rust (back-end) Fully open-source and self-hostable Focuses on data privacy and ownership What I find interesting: The tech stack choice - combining Flutter's UI capabilities with Rust's performance It's positioning as a privacy-focused alternative to Notion The potential for customization and extension due to its open-source nature
In plain words
AppFlowy is an open-source workspace application built with Flutter and Rust that functions as a privacy-focused alternative to Notion. It is fully self-hostable and designed for users who prioritize data ownership and control. The project emphasizes customization and extension capabilities through its open-source codebase, combining Flutter's user interface strengths with Rust's performance efficiency.
