Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
