Aider is an open source, terminal-based AI pair programming tool that edits files in an existing codebase, automatically committing changes to git as it goes. It connects to your own choice of LLM provider using your own API key, supporting models such as Claude, GPT and DeepSeek, as well as local models. Aider itself is free; you only pay your chosen LLM provider for API usage.
