Chatto
A self-hosted chat application for teams and communities with video calls, voice calls, and screen sharing.
Chatto is a self-hosted chat application designed for teams and communities who want full control over their communication platform. It provides a comprehensive suite of messaging features including real-time text chat, video calls, voice calls, and screen sharing — all privacy-first and GDPR compliant.
Built with a Go backend and a TypeScript + Svelte frontend, Chatto offers a modern, responsive experience across devices. The application is designed to be easy to deploy and maintain, making it a practical choice for organizations that want to move away from centralized platforms like Slack or Discord without sacrificing functionality.
Chatto is free and open source under the AGPL-3.0 license, with cloud hosting coming soon. The project is actively maintained with regular releases and a growing community.
