Kai's verdictA-tier. The right answer if you want open-source + terminal-native + model-agnostic.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for model-shopping. I use this for every prototype before committing.S-tier. Category leader. Nothing else is close yet.
