Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier. Bet on this one — the Sparkpage format is genuinely new.
