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**Junie CLI.** Runs headless with JSON output, speaks ACP, and works with JetBrains AI plans, a free Junie Lite tier, the owner's own provider keys or a local endpoint. Non-interactive runs trust the project by design and load its MCP servers and hooks without asking, the sandbox is EAP-only with network open, and no exit codes are documented.\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### Junie CLI\n\n1. Run headless only in repositories you trust. One-shot and piped runs load the project's MCP servers, hooks and skills without asking\n2. Set `JUNIE_API_KEY` (from junie.jetbrains.com/cli) or a provider key such as `JUNIE_ANTHROPIC_API_KEY` in CI. The default sign-in opens a browser\n3. Add `--output-format json` or `--json-output-file` to parse results. Check the output, since exit codes aren't documented\n4. Pass `--share-anonymous-statistics false` if no usage statistics may leave the runner\n5. Pin a build with `--use-version` and `--skip-update-check`. The CLI updates itself on start by default\n\n## Questions\n\n### Which is better for AI agents, HarnessRouter or Junie CLI?\n\nHarnessRouter and Junie CLI score within a point of each other on agent readiness, 53.2 (D) and 53.2 (D). Junie CLI leads on reliability, payments \u0026 pricing and transparency \u0026 trust.\n\n### Are HarnessRouter and Junie CLI open source?\n\nHarnessRouter 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.). No open-source release is listed for Junie CLI.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/harnessrouter-vs-junie.json, and with the fewest tokens: https://www.anchorterminal.com/compare/harnessrouter-vs-junie.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"harnessrouter\", \"b\": \"junie\"}`.
