AI pair programming in your terminal with LLMs
Aider enables developers to pair program with large language models directly from the command line, working seamlessly with existing codebases and supporting 100+ programming languages.
Aider brings AI pair programming directly into your terminal, letting you collaborate with leading LLMs like Claude 3.7 Sonnet, DeepSeek R1, and OpenAI o3-mini to build new projects or enhance existing codebases. Unlike browser-based coding assistants, Aider integrates deeply with your development workflow through native Git integration and codebase mapping.
Aider automatically maps your entire codebase to provide context-aware suggestions across large projects. It supports over 100 programming languages and commits changes with sensible messages, making it easy to review, diff, and roll back AI-generated code using standard Git workflows. The tool integrates with your existing IDE, accepts voice commands, and can process images and web pages for visual context.
Developers can leverage automatic linting and testing after each change, ensuring code quality without manual intervention. With 3.4M+ installations and processing 15B tokens weekly, Aider has proven itself in production environments. The project itself is 88% self-coded, demonstrating the tool's capability to handle complex, real-world software development tasks.
When teams consider Aider, these hosted platforms usually appear on the same shortlist.
