| Kai's verdict | S-tier. If you're on Vercel/shadcn, this is cheating. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. |
