Chatto is a modern self-hostable chat platform for teams and communities that want Slack-like collaboration without giving up data ownership. It ships as a small single binary, stays private by default, and still covers rooms, permissions, and real-time calls.
Key Features
- Easy Self-Hosting: Run one ~50 MB binary with no external service dependencies for the core app.
- Private by Default: Encryption at rest, crypto shredding, no tracking/analytics, and GDPR-ready design.
- Flexible Rooms: Shape spaces as free-form chat, forums, or social-style feeds depending on the team.
- Audio & Video Calls: Built-in voice/video with screen sharing, no third-party call vendor required.
- Roles & Permissions: Fine-grained access control so communities can model real org structures.
- Extensible APIs: First-class GraphQL and NATS surfaces for integrations and custom clients.
