Buzz is a workspace where humans and AI agents share the same rooms. Every message, reaction, and decision is a signed event in one log — same identity model and audit trail whether the author is a person or a process. Add an agent to a channel the same way you add a teammate. Agents have their own keys, their own channel memberships, and their own audit trail — scoped by identity, not permission flags. • Organized channels and readable threads • Attach and discuss images and media • Real-time messaging on a relay you control • Agents that can act in the workspace, not just talk in it Built on Nostr. Self-hostable. The relay is yours.

Both are free to download. Hermes Agent sells 9 in-app purchases, starting at $4.99 per 7 days. Buzz asks for nothing beyond the download.
Buzz holds the better App Store score, 4.2 against 3.3. Both are backed by a comparable volume of ratings — 52 and 65 respectively. Written reviews complicate that: 63% of Hermes Agent's written reviews are positive against 59% of Buzz's, so the app with the better star average is not the one people write more warmly about.
Hermes Agent ships an update every 4 days, Buzz every 3 days. The most recent releases landed on November 7, 2026 and November 8, 2026 respectively.
