AppFlowy

AppFlowy provides a self‑hostable, open‑source workspace for creating and managing detailed to‑do lists, kanban boards, databases, and documentation pages. It lets users organize tasks by project, track status, and customize views with blocks, properties, and themes, while supporting collaboration across desktop, mobile, and web clients. The platform includes an integrated AI assistant that can answer questions, generate text, and extract insights from content, with optional local model execution for privacy.

The software targets individuals and teams who need a flexible productivity tool without vendor lock‑in, offering a free tier and no subscription requirements. It is built with Flutter and Rust, released under the AGPL‑3.0 license, and can be run on macOS, Windows, Linux, iOS, and Android, or self‑hosted on any server. Community‑driven development supplies templates, plugins, and documentation for extending functionality.

Key distinguishing aspects are its open‑source licensing, self‑hosting capability, and on‑device AI that can run models such as Mistral 7B or Llama 3 locally, ensuring data remains under the user’s control while still providing collaborative, cross‑device productivity features.
