Aider is an open-source terminal-based pair programming tool that connects to any LLM provider. You add files to the chat, describe changes, and Aider edits them directly in your repo with clean diffs. It understands your git history and automatically creates well-formatted commits for every change. The repository map feature lets it understand code structure across large projects without stuffing everything into the context window. It supports Claude, GPT, Gemini, and local models via Ollama or LM Studio. Aider publishes its own code-editing leaderboards across models and has an active open-source community.
