| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes. | A-tier. The right answer if you want open-source + terminal-native + model-agnostic. | A-tier for designer-led sites. S-tier if animations matter. |
