Kai's verdictA-tier for designer-led sites. S-tier if animations matter.A-tier. Best for teaching a kid to code in 2026.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
