Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.B-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.
