| Kai's verdict | S-tier for solo + free. The best free option, hands down. | A-tier. The right answer if you want open-source + terminal-native + model-agnostic. | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | S-tier for text-in-image. Use this for posters, Midjourney for art. |
