Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best for fast prototypes. Competitive with Lovable — try both.S-tier. If you're on Vercel/shadcn, this is cheating.S-tier in the agent category. The first one I'd give to a non-technical friend.
