Ahead on: - Maintenance & community, 60 against 37 Watch for: No API, MCP server or A2A endpoint for an outside agent. ### 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 25 - Schema & documentation, 58 against 10 - Agent ergonomics, 52 against 0 - Security & auth, 59 against 0 - Transparency & trust, 68 against 56 Also in its favour: - Open source Watch for: No release, tag, published image or deploy guide; the README marks it early development ## Score by category | Category | Weight | Del | OpenDuet | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 25 | 42 | OpenDuet +17 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 10 | 58 | OpenDuet +48 | | Agent ergonomics | 13% (16.2 this run) | 0 | 52 | OpenDuet +52 | | Security & auth | 14% (17.5 this run) | 0 | 59 | OpenDuet +59 | | 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) | 60 | 37 | Del +23 | | Transparency & trust | 7% (8.8 this run) | 56 | 68 | OpenDuet +12 | | Negative events | ≤15 | 0 | 0 | | | **Total** | | **20.5 · F** | **49.5 · D** | | ## Facts side by side | Fact | Del | OpenDuet | | --- | --- | --- | | Kind | Platform | Agent harness | | Vendor | Human Interface, Inc. | CopilotKit (Tawkit, Inc.) | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | OAuth or key | OAuth or key | | Pricing | Paid | Freemium | | x402 | no | no | | Licence | Closed service under Del's Terms of Service (Human Interface, Inc., a Delaware corporation, last updated 5 August 2026). | MIT.

No outside agent can call it, no status page or security contact was found, and recent updates let some email actions skip approval. **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 ### Del 1. Don't plan to call Del from another agent. It answers only the owner's messaging threads and web workspace. 2. Tell the owner web browsing tasks are limited to five a month on Standard and unlimited on Pro. ### 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, Del or OpenDuet? OpenDuet scores 49.5 (D) on agent readiness against Del's 20.5 (F), and leads in 5 of 7 scored categories. Del leads on maintenance & community. ### Are Del and OpenDuet open source? No open-source release is listed for Del. 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/del-vs-openduet.json, and with the fewest tokens: https://www.anchorterminal.com/compare/del-vs-openduet.min.md - Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {"a": "del", "b": "openduet"}`.

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).
