| Kai's verdict | 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. | S-tier for open-source model APIs. The default in this space. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. |
