Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for open-source model APIs. The default in this space.A-tier. Close second to Cursor. If $5/mo matters, start here.
