Kai's verdictS-tier for builders. The right primitives. What Kai is built on under the hood.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for designer-led sites. S-tier if animations matter.S-tier for solo + free. The best free option, hands down.
