## Which one, for what

### Droid CLI (C)

Good for: Teams that want a terminal coding agent with tiered autonomy, command rules and an optional sandbox, and that will pay for a Factory plan.

Ahead on:
- Reliability, 49 against 35
- Security & auth, 63 against 58
- Maintenance & community, 79 against 72

Also in its favour:
- No incidents deducted, where HarnessRouter loses 5 points for them

Watch for: No free tier or trial was found. Plans start at $20 a month and included usage is stated only as rolling rate limits without numbers

### 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:
- Payments & pricing, 25 against 10
- Transparency & trust, 72 against 64

Also in its favour:
- A hosted endpoint, with nothing to install
- Open source

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

**Droid CLI.** `droid exec` is read-only unless `--auto` raises the autonomy level, with command rules, an optional kernel-enforced sandbox, JSON output and documented exit codes. No free tier, status page or security.txt was found, the source is closed, and usage metrics go to Factory by default.

**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

### Droid CLI

1. Set `FACTORY_API_KEY` (starts `fk-`) from the API keys page in Factory settings for headless runs. Interactive use signs in through a browser
2. Start with `droid exec` and no flags for analysis. Add `--auto low` for edits and `--auto medium` for installs, tests and local commits
3. Use `--output-format json` and read `is_error`, `num_turns` and `session_id`. Treat a non-zero exit code as failure
4. Set `sandbox.enabled` to true before running on untrusted code. In `droid exec` a sandbox violation is denied without a prompt
5. Pin the version in CI with `npm install -g droid@<version>`, or set `FACTORY_DROID_AUTO_UPDATE_ENABLED=false` on standalone installs, which update themselves

### 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
