What does Stoat do?
Stoat is an open-source group chat app designed for friends and communities. It offers servers, channels, voice chat, file sharing, and markdown support — everything you'd expect from a modern chat platform, but without ads, data mining, or shady partnerships. You can use it on desktop (Windows, macOS, Linux), mobile (Android, iOS), or directly in your browser. The app is built in Europe under strict data protection laws, and the code is public so anyone can inspect it.
Stoat scales from small friend groups to large communities. It has an intuitive role-based permissions system, moderation tools, and support for bots. Group DMs support up to 50 members and work with bots too. You can customize themes, use animated avatars, set profile banners, and upload files up to 20MB — all without a subscription. The app even lets you host your own server if you want full control. A public API is available, though this page doesn't link to documentation.
Stoat is best for people who want a reliable, no-nonsense chat app that respects their privacy. It's a solid choice for community organizers, friend groups, and developers who value open source and self-hosting. If you're tired of platforms that sell your data or push ads, Stoat offers a cleaner alternative that works everywhere.
