Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.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.S-tier for solo + free. The best free option, hands down.
