Best agent harnesses and coding agents · All 331 harnesses comparisons

Which one, for what

CLI Manager B

Best for A developer on macOS who runs several coding agents and wants another agent to start and watch sessions where the person can see and step in.

Ahead on

  • Reliability, 68 against 35
  • Payments & pricing, 60 against 25

Also in its favour

  • Free to start without a card
  • No incidents deducted, where HarnessRouter loses 5 points for them

Watch for

Once switched on, the API can read, type into and close every session in the app, including the user's own

HarnessRouter D

Best 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.

Ahead on

  • Agent ergonomics, 73 against 63
  • Maintenance & community, 72 against 62
  • Transparency & trust, 72 against 54

Also in its favour

  • A hosted endpoint, with nothing to install

Watch 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

Verdicts

CLI Manager

An agent can open visible terminal sessions, type into them, wait and read the screen through 12 typed MCP tools or a documented REST API, and the user can take any session back. The API reaches every open session once enabled, the app runs only on macOS, and none of the last 35 CI runs on the main branch passed.

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.

Before you call either

CLI Manager

  1. Ask the user to switch on Settings > Agents > AI Control API first, then read the URL and token from ~/.climanager/control-api.json
  2. On 409 awaiting_input, read the screen and answer with keys such as ["down","enter"]. Leave folder-trust and permission choices to the user
  3. Stop using a session on 409 disconnected. The user took it back
  4. Treat timedOut: true from wait as still running, not as a failure, and wait again
  5. Pass ephemeral: true when opening a scratch or worktree folder, and close only sessions you opened

HarnessRouter

  1. Name the harness yourself. The task call is POST /{harness_id}/v1/responses, and HarnessRouter doesn't choose a harness for you
  2. 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
  3. Call cancel to stop work. Closing the SSE connection leaves the agent running and billing
  4. Keep the Workspace API key on the server. The docs forbid calling the API from a browser with it
  5. Check each tool's enforcement in GET /v1/bases. On bases marked instruction, disabled_tools is a request to the model, not a block

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
