Kai's verdictA-tier. Best for fast prototypes. Competitive with Lovable — try both.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Still early. Manus is more flexible for less money.
