| Kai's verdict | A-tier. Best for teaching a kid to code in 2026. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for solo + free. The best free option, hands down. |
