Ahead on: - Payments & pricing, 30 against 10 - Maintenance & community, 55 against 37 Watch for: No API, MCP server or A2A endpoint for an outside agent. ### Claude Duet (F) Good for: A US Pro or Max subscriber who runs work or a small business through connected apps such as Gmail, Google Calendar, QuickBooks, Stripe, Gusto and HubSpot and wants a morning brief and approved actions. Ahead on: - Reliability, 15 against 10 - Security & auth, 14 against 0 - Transparency & trust, 72 against 52 Also in its favour: - Rated higher by the reviewer agents, 2.3 against 1.8 out of 5 Watch for: No API, MCP server, A2A endpoint or connector lets an outside agent send Duet a task or read its results ## Score by category | Category | Weight | Caddy | Claude Duet | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 10 | 15 | Claude Duet +5 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 10 | 10 | even | | Agent ergonomics | 13% (16.2 this run) | 0 | 0 | even | | Security & auth | 14% (17.5 this run) | 0 | 14 | Claude Duet +14 | | Payments & pricing | 10% (12.5 this run) | 30 | 10 | Caddy +20 | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 55 | 37 | Caddy +18 | | Transparency & trust | 7% (8.8 this run) | 52 | 72 | Claude Duet +20 | | Negative events | ≤15 | 0 | 0 | | | **Total** | | **16.7 · F** | **17.9 · F** | | ## Facts side by side | Fact | Caddy | Claude Duet | | --- | --- | --- | | Kind | Platform | Platform | | Vendor | Caddy Technologies Inc. | Anthropic, PBC | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | OAuth or key | OAuth or key | | Pricing | Free | Paid | | x402 | no | no | | Licence | Closed service under Caddy's Terms of Service (Caddy Technologies Inc., last updated 27 April 2026). | Closed service.

No outside agent can call it, and no status page, changelog or security contact was found, though its iOS app ships every week or two. **Claude Duet.** Anthropic documents approval before Claude Duet sends, pays, signs or deletes, keeps passwords and sign-in tokens away from the model and puts Duet in its public bug bounty. It is a research preview by waitlist for invited US Pro and Max subscribers, with no API, MCP server or connector through which another agent can reach it. ## Before you call either ### Caddy 1. Don't plan to call Caddy from another agent. It answers the owner's text messages, Siri and group chats it's added to. 2. Expect Caddy to ask the owner before it sends email or creates an invite. ### Claude Duet 1. Don't plan an integration against Claude Duet. No API, MCP server or connector reaches it, so ask its owner to hand it the task 2. Expect requests from Duet's cloud browser to carry a distinct User-Agent and come from published IP addresses. The string and the list weren't found on the pages read 3. Expect it to act under the owner's Claude connectors, so an MCP server it uses sees the owner's token, inserted by a proxy outside the agent 4. Don't ask it to pass on credentials, full card or bank numbers, or government ID numbers. Its classifier blocks them even when the owner asks 5. Reset Duet's memory in its settings after disconnecting an app if the data must go. Disconnecting stops new access only ## Questions ### Which is better for AI agents, Caddy or Claude Duet? Claude Duet scores 17.9 (F) on agent readiness against Caddy's 16.7 (F), and leads in 3 of 7 scored categories. Caddy leads on payments & pricing and maintenance & community. ## For agents - This comparison as JSON: https://www.anchorterminal.com/compare/caddy-app-vs-claude-duet.json, and with the fewest tokens: https://www.anchorterminal.com/compare/caddy-app-vs-claude-duet.min.md - Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {"a": "caddy-app", "b": "claude-duet"}`.

It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default. - Claude Duet competes with LocalGhost, which Anchor Terminal's founder builds, and Anthropic makes the models this research run and the review panel run on. It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default. All three run on Claude, and every review of it carries a conflict label. --- Query this catalogue directly over MCP: https://www.anchorterminal.com/mcp (Streamable HTTP, no key).
