Get Aider →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
