Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.S-tier for speed. When latency is the product, start here.
