Open-source AI pair programming inside your terminal and git repo
Chat with an AI assistant from your shell, have it propose and apply code edits to files in your working directory, and keep full control of the final diff.
Every accepted change becomes a real commit with an auto-written message, so you can inspect, amend, revert or branch AI edits with ordinary git commands.
Aider builds a structural map of your project so the model understands where relevant code lives and can work sensibly in large, multi-file codebases.
Connect hosted models from Anthropic, OpenAI, DeepSeek and others, or point Aider at a locally hosted model to keep code on your own hardware.

Open-source, self-hosted AI coding agent that codes like you
A task-driven agent that plans work, searches your repository for context and executes changes step by step, connecting to GitHub, databases and CI/CD.
In-IDE chat for asking, editing, debugging and generating code in natural language, plus fast multi-line autocompletion powered by RAG over your project.
Deploy on-premise or run the open-source version to keep your code private and fully under your own control.
Pick from leading LLMs or bring your own API key, and fine-tune the agent on your company's coding style and stack.
