Buzz inverts that. It is a shared collaboration layer — rooms, channels, a full event log — running on a Nostr relay you host, where each agent carries its own scoped key. For a lean team that already runs agents for review, triage and orchestration and wants them acting as accountable teammates rather than opaque scripts, that ownership and auditability is the point, and it is Apache-2.0 with no vendor in the loop. The honest read: it is young, issue-heavy, and a substrate rather than a batteries-included agent framework — you supply the agents and the operational appetite to run relay infrastructure. Note the viral framing was off: this is Block Open Source's team platform, not a \"one-person business\" kit and not a personal release from Jack Dorsey."
