Ahead on: - Reliability, 42 against 15 - Schema & documentation, 58 against 10 - Agent ergonomics, 52 against 0 - Security & auth, 59 against 0 - Payments & pricing, 30 against 20 - Transparency & trust, 68 against 44 Also in its favour: - Free to start without a card - Open source Watch for: No release, tag, published image or deploy guide; the README marks it early development ### Orbits (F) Good for: Families who want one shared assistant for calendars, lists, meals, chores and household email. Ahead on: - Maintenance & community, 54 against 37 Watch for: No public agent API, as llms.txt states. ## Score by category | Category | Weight | OpenDuet | Orbits | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 42 | 15 | OpenDuet +27 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 58 | 10 | OpenDuet +48 | | Agent ergonomics | 13% (16.2 this run) | 52 | 0 | OpenDuet +52 | | Security & auth | 14% (17.5 this run) | 59 | 0 | OpenDuet +59 | | Payments & pricing | 10% (12.5 this run) | 30 | 20 | OpenDuet +10 | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 37 | 54 | Orbits +17 | | Transparency & trust | 7% (8.8 this run) | 68 | 44 | OpenDuet +24 | | Negative events | ≤15 | 0 | 0 | | | **Total** | | **49.5 · D** | **15.7 · F** | | ## Facts side by side | Fact | OpenDuet | Orbits | | --- | --- | --- | | Kind | Agent harness | Platform | | Vendor | CopilotKit (Tawkit, Inc.) | Nemus AI, Inc. | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | OAuth or key | OAuth or key | | Pricing | Freemium | Paid | | x402 | no | no | | Licence | MIT.

Nine days old with no release, it needs a CopilotKit Intelligence account to start, sends usage telemetry at full sampling by default, and leaves most writes to an LLM reviewer unless the owner turns on asking. **Orbits.** Orbits is a family household app whose assistant, Bit, runs shared calendars, lists and meals, reads household email and places restaurant calls after approval, with iOS releases every week or two. No outside agent can call it, prices appear only as App Store in-app purchases, and no status page, security contact or named subprocessors were found. ## Before you call either ### OpenDuet 1. Follow the README's Quick start (`bun install`, `bash scripts/start.sh`), not the announcement's `npm run dev`, which the repository has no script for. 2. Run `bun openbot/scripts/setup-learning.ts` after `copilotkit project select`; the server reads `INTELLIGENCE_API_KEY`, not the `CPK_` key the CLI writes. 3. Turn on 'ask before making changes' in `/settings/approvals` if every write should pause; the default leaves most writes to the LLM reviewer. 4. To bring your own agent, register it as a `remote-ag-ui` Bot in `agents.yaml`; its tool calls still pass through the gateway's policy and audit. 5. Set `COPILOTKIT_TELEMETRY_DISABLED=true` or `DO_NOT_TRACK=1` before starting if usage events must not reach CopilotKit. ### Orbits 1. Don't plan to call Orbits from another agent. llms.txt says no public agent API is offered. 2. Tell the owner the assistant needs an Orbits subscription bought in the app, and that any trial appears only at purchase. ## Questions ### Which is better for AI agents, OpenDuet or Orbits? OpenDuet scores 49.5 (D) on agent readiness against Orbits's 15.7 (F), and leads in 6 of 7 scored categories. Orbits leads on maintenance & community. ### Are OpenDuet and Orbits open source? OpenDuet is open source (MIT. Threads and memory need a CopilotKit Intelligence project, a separate service under CopilotKit's Self-Service Agreement). No open-source release is listed for Orbits. ## For agents - This comparison as JSON: https://www.anchorterminal.com/compare/openduet-vs-orbits.json, and with the fewest tokens: https://www.anchorterminal.com/compare/openduet-vs-orbits.min.md - Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {"a": "openduet", "b": "orbits"}`.

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. --- Query this catalogue directly over MCP: https://www.anchorterminal.com/mcp (Streamable HTTP, no key).
