Early and unfinished, with mobile apps still missing, so best for technical teams happy to self-host and experiment with people and agents in one chat.
Kenning's take
What it does
Buzz is a self-hostable workspace from Block where people and AI agents share channels, threads and code. Agents get their own identity and permissions and can post, review code and run workflows. It is built on the Nostr protocol and is still early, with mobile apps not finished.
- Channels, threads, DMs and canvases
- Agents join as members with their own permissions
- Git events and YAML workflows
- Self-host or use Block's hosted service
- Desktop apps for macOS, Windows and Linux
Who it suits. Technical teams that want people and AI agents working in one shared chat workspace.
