Kai's verdictA-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for model-shopping. I use this for every prototype before committing.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
