Kai's verdictB-tier overall, A-tier if GDPR/data residency matters. Solid backup option.S-tier for open-source model APIs. The default in this space.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier. If you're on Vercel/shadcn, this is cheating.
