Wedel, Germany
Founded 2025

Chatto is a fast, fully-featured, self-hostable chat application built for teams and communities who want to own their conversations. Distributed as a single binary with no external dependencies, it supports real-time messaging, voice and video calls with screen sharing, fine-grained roles and permissions, and modular server-side extensions. Chatto encrypts message text and account data with per-user keys and supports crypto-shredding on account deletion. A hosted cloud offering, Chatto Cloud, is also available for teams that prefer managed infrastructure.
