What is Chatto?

Chatto is an open-source, self-hosted communication platform similar to Discord. It provides communication tools like channels, voice and video calling, and file uploading. It also supports plugins, roles, and permissions.

The software can be run on personal servers or through Chatto's cloud hosting. It prioritizes privacy with encryption, no tracking, and GDPR compliance.

Chatto's rooms can be customized to fit different communication styles. Its voice and video call features are built into the service, removing the need for third-party applications.
