Kai's verdictS-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier. If you're on Vercel/shadcn, this is cheating.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for solo + free. The best free option, hands down.
