Score breakdown
Pros
- Genuinely free tier with up to 100M Muse tokens a week — most consumer agents gate any real use behind a paywall
- Runs in the background after the app is closed and comes back when something changes or needs approval
- Isolated Muse Secure VM plus a Sentinel agent that approves every connector action, with a secure credential store the agent cannot read
- Checkout for purchases runs through Link by Stripe with one-time card numbers and purchase protections
Cons
- Requires a payment card even on the free tier
- US-only (with Canada) and 18+ as of launch; paid tiers may vary by region and account
- Deeply tied to Meta's apps (Facebook, Instagram, WhatsApp, Muse) — a Google- or Apple-centric user gets less value

Free plan available
OpenAI's always-on coding agent, bundled into ChatGPT with no separate subscription — CLI, IDE, cloud tasks and automatic code review across GPT-5.x model tiers.
Score breakdown
Pros

- Broadest cloud-agent surface: web, CLI, IDE extension, iOS, automatic code review and Slack integration on Plus and up
- Clear scaling path: 5x (Pro $100) and 20x (Pro $200) rate-limit multipliers for all-day and 7x24 automation
Cons
- No standing free agent tier — the Free entry is a time-boxed promo trial, not a free plan you can rely on
- Go at $8/mo does not include Codex, so the usable floor is effectively Plus at $20/mo
- Usage limits are model- and task-dependent estimates, not fixed message counts, which makes budgeting harder than per-seat tools
