Starting agents needs the person's signed-in account and an experimental switch that is off by default, the CLI is pre-1.0, and usage counts are shared by default.\n\n**HarnessRouter.** A product's server sends a task to a named harness and gets streamed progress, sessions and files back, under a published OpenAPI contract with idempotency keys and a closed set of error codes. 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## Before you call either\n\n### Harness\n\n1. Run `harness whoami` first. If it says you may not start harnesses, tell the person and do the work yourself\n2. Ask the person before installing Harness, and leave `harness login` and the agents-start-agents switch to them\n3. Treat exit 5 as final and do not retry. Treat exit 3 as needs the person, and never answer a harness's question or permission prompt\n4. Name every harness, put the whole task in `harness new`, then wait, read with `harness show` and close only the ones you started\n5. Run each `harness` command on its own or joined with `\u0026\u0026`, since piped commands no longer match the permission rule\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## Questions\n\n### Which is better for AI agents, Harness or HarnessRouter?\n\nHarness scores 60.3 (C) on agent readiness against HarnessRouter's 53.2 (D), and leads in 3 of 7 scored categories. HarnessRouter leads on maintenance \u0026 community.\n\n### Are Harness and HarnessRouter open source?\n\nYes. Harness is open source (MIT). 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.).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/harness-autonomous-vs-harnessrouter.json, and with the fewest tokens: https://www.anchorterminal.com/compare/harness-autonomous-vs-harnessrouter.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"harness-autonomous\", \"b\": \"harnessrouter\"}`.
