Watch for: No approval setting or list of actions that need confirmation was found on the public pages. The terms say it sends emails, SMS and calls following the user's instructions. ### OpenDuet (D) Good for: A starting point for a developer or team who wants a proactive mail-and-calendar assistant they host and change, with approvals and audit, and who accepts a CopilotKit Intelligence account. Ahead on: - Reliability, 42 against 35 - Schema & documentation, 58 against 4 - Agent ergonomics, 52 against 6 - Security & auth, 59 against 13 - Transparency & trust, 68 against 52 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 ## Score by category | Category | Weight | Haven | OpenDuet | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 35 | 42 | OpenDuet +7 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 4 | 58 | OpenDuet +54 | | Agent ergonomics | 13% (16.2 this run) | 6 | 52 | OpenDuet +46 | | Security & auth | 14% (17.5 this run) | 13 | 59 | OpenDuet +46 | | Payments & pricing | 10% (12.5 this run) | 30 | 30 | even | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 35 | 37 | OpenDuet +2 | | Transparency & trust | 7% (8.8 this run) | 52 | 68 | OpenDuet +16 | | Negative events | ≤15 | 0 | 0 | | | **Total** | | **22.3 · F** | **49.5 · D** | | ## Facts side by side | Fact | Haven | OpenDuet | | --- | --- | --- | | Kind | Platform | Agent harness | | Vendor | Hello Haven, Inc. | CopilotKit (Tawkit, Inc.) | | Hosted endpoint | no (local only) | no (local only) | | Transports | HTTP | | | Auth | OAuth or key | OAuth or key | | Pricing | Free | Freemium | | x402 | no | no | | Licence | Proprietary service under Hello Haven's Terms of Service | MIT.

No public page read says which actions need approval, which accounts it connects or how their tokens are kept, and it names no model provider or sub-processor. **OpenDuet.** Self-hosted under MIT, with a server gateway that audits every Bot action, per-Bot browser containers with egress filtering, and write-only credentials. 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. ## Before you call either ### Haven 1. Haven has no documented API or MCP server. An outside agent can reach it only through the owner's channels (call, SMS, email, app). 2. Do not assume an approval step before Haven sends mail, texts or calls. None is documented on the public pages. 3. Email Haven sends to other people names Hello Haven as sender and says it was sent on the user's behalf, per the terms. 4. Chat messages, history, profile context and uploaded files go to third-party AI model providers that the vendor does not name. 5. Check status.hellohaven.ai before relying on phone or voice. All four published incidents affected those channels. ### 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. ## Questions ### Which is better for AI agents, Haven or OpenDuet? OpenDuet scores 49.5 (D) on agent readiness against Haven's 22.3 (F), and leads in 6 of 7 scored categories. ### Are Haven and OpenDuet open source? No open-source release is listed for Haven. OpenDuet is open source (MIT. Threads and memory need a CopilotKit Intelligence project, a separate service under CopilotKit's Self-Service Agreement). ## For agents - This comparison as JSON: https://www.anchorterminal.com/compare/haven-vs-openduet.json, and with the fewest tokens: https://www.anchorterminal.com/compare/haven-vs-openduet.min.md - Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {"a": "haven", "b": "openduet"}`.
