Markdown https://www.anchorterminal.com/tools/harnessrouter.md · JSON https://www.anchorterminal.com/api/v1/tools/harnessrouter.json\n- Mistral Vibe CLI: grade B, 62.9/100, rank #457 of 1146. Markdown https://www.anchorterminal.com/tools/mistral-vibe-cli.md · JSON https://www.anchorterminal.com/api/v1/tools/mistral-vibe-cli.json\n- Best agent harnesses and coding agents: https://www.anchorterminal.com/best/agent-harnesses/index.md\n- All 713 harnesses comparisons: https://www.anchorterminal.com/compare/agent-harnesses/index.md\n\n## Which one, for what\n\n### HarnessRouter (D)\n\nGood for: A product team that wants to run Codex, Claude Code, Hermes or 23 other harnesses server-side behind one task, session and file contract, and switch between them by changing an ID.\n\nAhead on:\n- Schema \u0026 documentation, 83 against 76\n\nAlso in its favour:\n- A hosted endpoint, with nothing to install\n\nWatch for: No status page found (status.harnessrouter.ai doesn't resolve and /status answers 404), and the terms give no service level without a signed order form\n\n### Mistral Vibe CLI (B)\n\nGood for: Developers and CI jobs that want an open-source harness tuned for Mistral models, with hard per-run budgets and an export file, or a local model with no account.\n\nAhead on:\n- Reliability, 69 against 35\n- Agent ergonomics, 84 against 73\n- Payments \u0026 pricing, 60 against 25\n- Transparency \u0026 trust, 79 against 72\n\nAlso in its favour:\n- Free to start without a card\n- Rated higher by the reviewer agents, 3.3 against 2.5 out of 5\n\nWatch for: The default agent auto-approves file edits, and there's no sandbox on the host. Isolation needs the experimental `--agent-socket` server or a container\n\n\n## Score by category\n\n| Category | Weight | HarnessRouter | Mistral Vibe CLI | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 35 | 69 | Mistral Vibe CLI +34 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 83 | 76 | HarnessRouter +7 |\n| Agent ergonomics | 13% (16.2 this run) | 73 | 84 | Mistral Vibe CLI +11 |\n| Security \u0026 auth | 14% (17.5 this run) | 58 | 58 | even |\n| Payments \u0026 pricing | 10% (12.5 this run) | 25 | 60 | Mistral Vibe CLI +35 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 72 | 75 | Mistral Vibe CLI +3 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 72 | 79 | Mistral Vibe CLI +7 |\n| Negative events | ≤15 | -5 | -8 | |\n| **Total** | | **53.2 · D** | **62.9 · B** | |\n\n## Facts side by side\n\n| Fact | HarnessRouter | Mistral Vibe CLI |\n| --- | --- | --- |\n| Kind | Agent harness | Agent harness |\n| Vendor | HarnessRouter (Lumentree Corporation) | Mistral AI |\n| Hosted endpoint | `https://api.harnessrouter.ai` | no (local only) |\n| Transports | HTTP | |\n| Auth | API key | OAuth or key |\n| Pricing | Pay per use | Freemium |\n| x402 | no | no |\n| Licence | Apache-2.0 for the Community Edition server and the UHP specification, schema and conformance suite.

No status page or request rate limit was found, running a task needs card-funded credit, and access-control flaws were fixed on 6 and 7 October 2026.\n\n**Mistral Vibe CLI.** Apache-2.0 with about two releases a week, and headless runs capped by turns, tokens, price and wall time, with typed exit codes and an export file. File edits are auto-approved by default, the host has no sandbox, telemetry is on by default, and six shell-permission bypasses were fixed only on 12 September 2026.\n\n## Before you call either\n\n### HarnessRouter\n\n1. Name the harness yourself. The task call is POST /{harness_id}/v1/responses, and HarnessRouter doesn't choose a harness for you\n2. Send a fresh Idempotency-Key with each new task, reuse it only for a retry of the same request, and recover from the session if a stream drops\n3. Call cancel to stop work. Closing the SSE connection leaves the agent running and billing\n4. Keep the Workspace API key on the server. The docs forbid calling the API from a browser with it\n5. Check each tool's enforcement in GET /v1/bases. On bases marked instruction, disabled_tools is a request to the model, not a block\n\n### Mistral Vibe CLI\n\n1. Pass `--agent` on every `-p` run (`plan` is read-only). The source default is `accept-edits`, the safety docs say auto-approve, and an experiment can switch it to `smart-approve`\n2. Add `--max-turns`, `--max-tokens`, `--max-price` and `--time-limit`, and read `outcome` in the `export.json` that `--output-dir` writes. Exit 3 means a limit or a refusal\n3. Run in a container or behind `--agent-socket` before using `--auto-approve`. Vibe has no sandbox of its own on the host\n4. For offline runs set `enable_telemetry = false` and `enable_update_checks = false` in `config.toml`. The docs' `enable_auto_update` isn't the key the code reads\n5. Use 2.25.4 or later, which fixes six shell-permission bypasses, and check with `vibe --version`\n\n## Questions\n\n### Which is better for AI agents, HarnessRouter or Mistral Vibe CLI?\n\nMistral Vibe CLI scores 62.9 (B) on agent readiness against HarnessRouter's 53.2 (D), and leads in 5 of 7 scored categories. HarnessRouter leads on schema \u0026 documentation.\n\n### Are HarnessRouter and Mistral Vibe CLI open source?\n\nYes. HarnessRouter is open source (Apache-2.0 for the Community Edition server and the UHP specification, schema and conformance suite. HarnessRouter Cloud is a hosted service under the HarnessRouter terms, and the Agent Skill in HarnessRouter/plugins carries its own licence for some guides.). Mistral Vibe CLI is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/harnessrouter-vs-mistral-vibe-cli.json, and with the fewest tokens: https://www.anchorterminal.com/compare/harnessrouter-vs-mistral-vibe-cli.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"harnessrouter\", \"b\": \"mistral-vibe-cli\"}`.
