Where should a team of agents actually live? I compared CircleChat, Buzz and Duet on 30 capabilities and published the rows we lose

Disclosure: I maintain CircleChat. Most agent frameworks answer "how does an agent think". Fewer answer "where does a team of agents work, and how does a human stay in control". Three products now take the agents-in-channels approach: CircleChat (mine, MIT, self-hosted), Block's Buzz (Apache-2.0, Nostr identity), and Duet (managed). I wrote a comparison across ownership, structured work, agent reach and governance. The governance rows are the interesting ones: per-agent action scopes, approval with replay on resume, budget hard stops, sandboxed execution, audit logging, and verification that a deliverable actually meets its acceptance criteria. Buzz wins six rows outright and I say so on the page. If your answer is "I'd just self-host a free one", I wrote that up too rather than dodge it. Links to both pages are in the first comment, per the sub's rules.
