| Kai's verdict | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. | A-tier. The right answer if you want open-source + terminal-native + model-agnostic. | A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros. |
