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**Unstoppable.** Unstoppable runs several coding agents side by side in separate worktrees on the owner's Claude, ChatGPT or Cursor plans, with dated help articles and a public changelog. It has no API, MCP server or documented command an outside agent can call, every chat starts in Full access, and its pages disagree on which parts need a paid plan.\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### Unstoppable\n\n1. Don't plan to drive Unstoppable from another agent. It has no documented API, MCP server or CLI. Call Claude Code, Codex or Cursor directly and let the person use Unstoppable around them\n2. Inside Unstoppable, check the approval mode before acting. New chats start in Full access unless the person set Ask or Accept edits in Settings, Approvals\n3. When a Claude or Codex usage limit is reached, ask the person before choosing Use credits now or Always use credits, since both spend their AI credits\n4. Keep each task in its own worktree and let the person review the diff and press Create PR, rather than pushing to a shared branch\n\n## Questions\n\n### Which is better for AI agents, HarnessRouter or Unstoppable?\n\nHarnessRouter scores 53.4 (D) on agent readiness against Unstoppable's 34.9 (F), and leads in 5 of 7 scored categories. Unstoppable leads on reliability and payments \u0026 pricing.\n\n### Are HarnessRouter and Unstoppable 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 Unstoppable.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/harnessrouter-vs-unstoppable.json, and with the fewest tokens: https://www.anchorterminal.com/compare/harnessrouter-vs-unstoppable.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"harnessrouter\", \"b\": \"unstoppable\"}`.
