Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for solo + free. The best free option, hands down.A-tier. S-tier if you self-host. The reason open-source image gen matters.
