Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Still early. Manus is more flexible for less money.A-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.
