Aider was the original git-native CLI coding agent, and it is still the cleanest way to keep AI edits reversible: every change lands as a commit you can read and roll back. It is Apache-2.0 (not MIT, despite what some write-ups say).

If you live in the terminal and want an audit trail for every AI-made change, Aider is hard to beat.

The good

  • Git-native, every change is a reviewable commit
  • Terminal-first, scriptable
  • Model-agnostic

The catch

  • CLI workflow is not for everyone
  • You pay model costs
  • Less visual than editor-based agents

Pricing

Free and open source. Model API costs are yours.

Alternatives to consider

  • Cline An autonomous in-editor coding agent, fully open and BYO-key.
  • Tabby A self-hosted coding assistant for air-gapped and privacy-first teams.
