## 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 13
- Agent ergonomics, 72 against 64
- Security & auth, 63 against 57
- Maintenance & community, 79 against 18
- Transparency & trust, 64 against 44

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

### Jules (E)

Good for: A person or pipeline that wants to hand scoped GitHub tasks to a cloud agent and collect a pull request or a patch, or run a repoless job in a disposable VM.

Ahead on:
- Payments & pricing, 30 against 10

Also in its favour:
- Runs on your own machine

Watch for: The REST API has been v1alpha since 3 October 2025 and the docs say specifications and API keys may change

## 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.

**Jules.** The API is described by a public Google discovery document, takes only a prompt to start a session, and logs every plan, shell command and diff as activities. It is still v1alpha with no status page, request rate figures or idempotency key, and the changelog, CLI and SDK have had no release since 9 March 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

### Jules

1. Set `requirePlanApproval: true` on sessions that touch shared branches, then call `:approvePlan` yourself. API sessions otherwise run their plan without review
2. Session creation has no request ID. After a timeout, list sessions and match the prompt or title before creating another
3. Poll activities with a `create_time` filter and cache them. Activities never change once written
4. Read the request fields from the discovery document at https://jules.googleapis.com/$discovery/rest?version=v1alpha. The field tables on jules.google render empty
5. Budget against the daily task quota of 15, 100 or 300 by plan. New sessions are refused until the rolling 24 hours reset
