Kai's verdictA-tier. Best for fast prototypes. Competitive with Lovable — try both.S-tier infrastructure. The one platform every AI dev eventually uses.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.
