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**MiniMax Code.** An MIT-licensed terminal coding agent with a headless mode that returns versioned JSON, documented exit codes and an ACP server, and telemetry off by default. It's pre-1.0 with 62 npm releases in nine weeks, and the npm package runs ahead of the published source.\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### MiniMax Code\n\n1. Run `mcode exec --cwd \u003crepo\u003e --output-format json --timeout 10m --max-steps 50` and check both the exit code and the JSON `status`\n2. Keep `--permission full` and `off` for a container or throwaway workspace. The default `smart` fails when it would need a person\n3. Set `MCODE_PROVIDER_API_KEY` and add a provider for BYOK. M Plan models need a browser sign-in with `mcode login --region global`\n4. Set `MINIMAX_DATA_DIR` per CI runner. Keys and sessions live in `~/.minimax` by default\n5. Pin a version. npm published 62 releases in nine weeks and the public source trails it\n\n## Questions\n\n### Which is better for AI agents, HarnessRouter or MiniMax Code?\n\nMiniMax Code scores 67.5 (B) on agent readiness against HarnessRouter's 53.2 (D), and leads in 4 of 7 scored categories. HarnessRouter leads on transparency \u0026 trust.\n\n### Are HarnessRouter and MiniMax Code 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.). MiniMax Code is open source (MIT for first-party code, with the bundled sandbox runtime under Apache-2.0. The desktop app's source isn't published).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/harnessrouter-vs-minimax-code.json, and with the fewest tokens: https://www.anchorterminal.com/compare/harnessrouter-vs-minimax-code.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"harnessrouter\", \"b\": \"minimax-code\"}`.
