Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.S-tier for speed. When latency is the product, start here.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
