Aider — open source alternative

AI pair programming in your terminal.

Strengths

  • Git-aware — edits files and commits for you.
  • Works with any OpenAI-compatible model.
  • Lightweight — runs as a CLI.

Weaknesses

  • Terminal-based — no GUI for editors.
  • Model API usage costs can climb on large repos.
  • Not a code-completion tool (different UX from Copilot).
