## The Hook

Buzz is Block/Cash App–scale Rust workspace where humans and agents share the same rooms as keyed members on a Nostr event-log relay you own.

## What's Good

Apache-2.0 (block/buzz). Self-host relay+desktop via `just dev`, Releases (squareup/buzz-releases), or production compose; agent surface via buzz-cli + ACP (Goose/Codex/Claude Code). Signed event log for messages, reviews, workflows, and git events — same identity model for people and processes. ★34,862 on GitHub API 2026-09-27.

## The Catch

Vs OpenClaw: messaging channels/employee, not a Nostr event-log collab workspace. Vs Multica: coding-agent issue board. Vs Paperclip: org budgets/Board governance. Org maturity reads prototype; ~3.6k open issues; Block-internal paths and optional Railway one-click are extras, not OSS walls.

## Verdict

Apache-2.0 self-host human+agent rooms when a keyed event-log workspace beats another board or messaging bot — expect prototype heat and issue volume.
