Kai's verdictA-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.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.
