Kai's verdictA-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier for model-shopping. I use this for every prototype before committing.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.
