Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier. Best for fast prototypes. Competitive with Lovable — try both.A-tier. S-tier if you self-host. The reason open-source image gen matters.
