Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. Bet on this one — the Sparkpage format is genuinely new.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
