## Which one, for what

### HarnessRouter (D)

Good 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:
- Security & auth, 58 against 45
- Transparency & trust, 72 against 62

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

### Kimi Code CLI (B)

Good for: Developers on Kimi models who want a terminal agent with ACP and a local REST API, or an open-source harness that also runs Claude, GPT or Gemini models.

Ahead on:
- Reliability, 68 against 35
- Payments & pricing, 60 against 25

Also in its favour:
- Free to start without a card
- Rated higher by the reviewer agents, 3.0 against 2.5 out of 5

Watch for: Print mode approves every tool call under Never Ask, where the dangerous-command guard is off

## Verdicts

**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.

**Kimi Code CLI.** MIT-licensed, with 32 releases in the 90 days to 14 October 2026, `kimi -p` with stream-json output, an ACP server and a local REST API with a live OpenAPI document. Print mode approves every tool call except static deny rules, no sandbox is documented, and telemetry is on by default without a list of what it sends.

## Before you call either

### 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

### Kimi Code CLI

1. `kimi -p` approves every tool call. Add `[[permission.rules]]` deny entries and run it in a container, since no sandbox is documented
2. Set `KIMI_LOOP_MAX_STEPS_PER_TURN` for unattended runs. Steps per turn are unlimited by default
3. Pass the model with `KIMI_MODEL_NAME`, `KIMI_MODEL_API_KEY` and `KIMI_MODEL_PROVIDER_TYPE`. `OPENAI_API_KEY` or `ANTHROPIC_API_KEY` in the shell is ignored otherwise
4. Set `KIMI_DISABLE_TELEMETRY=1` and use 0.41.0 or later, since earlier print-mode runs ignored it
5. Install `@moonshot-ai/kimi-code` or the `kimi-code` formula. The `kimi-cli` and `kimi-code` packages on PyPI are the archived Python CLI
