The honest brief

Aider

CLI-only and model-agnostic: auto-commits every AI edit as its own git commit, so changes are trivially revertable.

  • Fully open-source, BYO-key
  • Auto-commits each edit to git
  • Works with any model incl. local
  • Strong on its own Polyglot benchmark
  • No editor lock-in — pure terminal
  • No GUI — terminal comfort required
  • You pay model API costs yourself
  • Less hand-holding than IDE agents
  • Setup/config heavier than hosted tools

Crush

Charm's signature TUI polish over a model-agnostic terminal agent: switch providers mid-session and keep code, keys, and data on your own machine.

  • Polished, keyboard-driven terminal UI
  • BYO keys for many providers
  • LSP-aware code context
  • Runs locally; you control keys and data
  • Requires your own model API keys
  • Beta — some features still missing
  • FSL license is not OSI open-source yet
