  • Runs locally, edits your actual files
  • Strong on large codebases with 1M context
  • Great at multi-step tasks
  • Cheaper than Cursor
  • Cascade agent for multi-file tasks
  • Solid free tier
Weaknesses
  • Open-weight models only (no Claude/GPT)
  • Less flexibility on custom configs
  • Can feel overwhelming for non-coders

  • Terminal-based — learning curve
  • Can't be used without Claude subscription
  • Smaller community
  • Model selection more limited
Kai's verdictS-tier for speed. When latency is the product, start here.S-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. Close second to Cursor. If $5/mo matters, start here.
