AppFlowy

AppFlowy is an open-source, AI-powered collaborative workspace and leading Notion alternative where you stay in full control of your data.

🚀 Overview

AppFlowy is the AI collaborative workspace that brings projects, wikis, and teams together, allowing you to achieve more without losing control of your data. It solves the core problems of proprietary productivity tools like Notion: vendor lock-in, privacy risks, and dependency on cloud services by providing a local-first, offline-capable app with on-device AI and self-hosting options.

It's built for individuals, teams, and enterprises who prioritize data ownership, customization, and seamless cross-platform experience. Whether you're managing personal notes, team wikis, or complex databases, AppFlowy keeps everything accessible and private.

The project was created by a global community of over 10K members from 215 countries and 400+ contributors to deliver a powerful, extensible alternative that's truly open-source and community-driven.
