Aider

Coding Tools

AI pair programming in your terminal.

What it’s for

Aider edits your git-tracked files directly from the CLI, writes clean commits, and works with any model — from Claude and GPT to local Ollama models. Perfect for developers who live in the terminal and want AI without leaving it.

How to use it

pip install aider-chat, run aider inside a git repository, and describe the change you want. Review the diff before committing; add files to the chat with /add to control context. Bring your own API key.

Pricing

Free and open source (Apache 2.0). You pay your model provider for tokens.
