Pros
  • Free, open-source terminal pair-programmer that works with almost any LLM, local models included
  • Git-native: every change is an atomic commit you can undo
  • Repo map and multi-file edits handle real codebases
  • Agentic coding from your terminal: edits files, runs commands, finishes tasks
  • Included with Claude Pro, so there's no separate subscription to start
  • Max plans add more usage plus $100–$200/mo in API credits
Catches
  • Terminal-only: no inline autocomplete or visual diffs
  • You manage context by hand, and setup takes configuration
  • API spend is uncapped. Heavy refactors on frontier models get pricey
  • Weekly limits can drain in a few sessions on Pro, per GitHub issues
  • A user-filed bug reports limits draining ~3.6x faster after the Sept 25 reset (unconfirmed by Anthropic)
  • Real daily use tends to push you to $100+/mo Max
