|description=MIT-licensed, self-hostable team chat with channels, voice/video, and broad
integration support. Its omnichannel inbox unifies live chat, email, WhatsApp, and
Telegram into one agent queue -- useful if you also want to replace a separate
customer-support tool, not just internal chat.
|usage_notes=Has the most GitHub momentum of the self-hosted Slack alternatives
(~45k stars). The free Community edition covers most day-to-day needs; exceeding
Starter-plan limits blocks adding new users but does not lock you out of existing
data.
