Weaknesses
  • Can feel overwhelming for non-coders
  • Expensive at scale
  • Terminal-based — learning curve
  • Can't be used without Claude subscription
  • Terminal-only
  • Less agentic than Claude Code
  • Setup on Windows is fiddly
  • Quality ceiling for complex apps
  • Can get into loops for non-trivial bugs
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. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. Best for fast prototypes. Competitive with Lovable — try both.
