Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier. Useful for first drafts. v0 is the better bet for shipping code.S-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.
