Kai's verdictA-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.A-tier in its niche. The only one that actually gets emotion right.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.
