Tinode
Open-source instant messaging server with a Go backend and multi-platform clients
Overview
Tinode is an open-source instant messaging platform with a high-performance Go backend and clients for web, Android, iOS, and command line. It positions itself as a modern alternative to XMPP and a self-hostable base for building chat into products. Suitable for teams and developers wanting an embeddable messaging server.
Where it falls short of Slack
- More of a messaging backend/SDK than a turnkey Slack workspace experience
- Lacks built-in app marketplace, workflows, and rich integrations of Slack
- Voice/video is limited compared to Teams
- Admin and team-management UI is minimal
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
