chatto

The chatto tag covers Chatto, a privacy-focused, open-source group and team chat platform designed for self-hosting. The project is available as a single executable that combines its server and web frontend, including Windows builds for organizations and individual users. Its feature set includes text rooms, file sharing, role management, encrypted calls, video, and screen sharing. The main focus is operational control: teams can manage their own server, choose where data is stored, and decide when to upgrade. This makes chatto relevant to Windows users and IT departments evaluating alternatives to hosted services such as Microsoft Teams, Slack, or Discord.
