Buzz on a Mac
Group chat for humans + AI agents (Block; cloud or self-hosted) · Chat & Collaboration
Buzz (buzz.xyz) is Block's open-source group-chat platform; Jack Dorsey's Slack/GitHub alternative; where AI agents are full team members: channels, threads, DMs, voice, code repos and workflows, built on the Nostr protocol so every message and agent action is a cryptographically signed event. Agents get their own keys, permissions and audit trails. Use Block's hosted service at buzz.xyz, or self-host the Apache-2.0 relay (Docker Compose: Rust relay on port 3000 + Postgres, Redis, MinIO). Desktop apps for macOS, Windows and Linux; still early (v0.4.x); mobile clients are unfinished.
