|---|---|---|---|---|
| Tagline | Cognition Labs' autonomous coding engineer. | Wire Cursor's full coding-agent runtime into your own apps, scripts, and CI/CD pipelines with a few lines of TypeScript. | Sales-focused meeting AI with CRM integration. | VS Code fork that made AI coding actually work. |

| Pricing | $500/mo | Token-based; requires Cursor plan (Pro from $20/mo). Composer 2 at $0.50/$2.50 per M tokens (in/out); fast variant $1.50/$7.50 per M tokens. | Free + $10-$19/user/mo | Free + $20/mo Pro + $40/mo Business |
| Best for | Engineering teams offloading tickets. Ops/platform work. | Engineering teams who already use Cursor and want to embed its coding-agent runtime into CI/CD pipelines, backend services, or internal developer tools without building agent infrastructure from scratch. | Sales teams, customer success, anyone running many discovery calls. | Developers. Non-developers who want to ship working code. |

| Kai's verdict | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | If your team is already in the Cursor ecosystem, this is a genuinely compelling way to turn ad-hoc AI coding sessions into durable, automated workflows — but the beta label and Cursor's history with opaque pricing mean you'll want to set hard budget guardrails before going to production. (Verdict pending Phi's full review.) | A-tier for sales teams. B-tier for solo users. | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. |
