Kai's verdictB-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.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
