Kai's verdictS-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
