Kai's verdictA-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
