Kai's verdictS-tier for open-source model APIs. The default in this space.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.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
