Kai's verdictA-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.A-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. If you're on Vercel/shadcn, this is cheating.
