What it does
RustChat is an open-source, self-hosted team communication platform for technical teams. Its official site describes channels, threads, direct messages, files, calls, search, and integrations; the homepage labels it a public preview.
RustChat brings channels, threaded discussions, direct messages, files, calls, and search into a self-hosted workspace for technical and operational teams. The vendor also describes API compatibility surfaces for Mattermost integrations. The site labels the service a “Public Preview / Open Source Preview,” so it should be treated as an early-stage product rather than a mature production reference. No server or message workflow was tested.
