Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for solo + free. The best free option, hands down.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
