Aider

Aider is an open-source AI coding assistant that runs in your terminal, connecting to various LLMs like Claude, DeepSeek, and OpenAI models to help you edit code. It automatically commits changes to git, maps your entire codebase for large projects, and supports over 100 programming languages. Features include IDE integration, image and web page context, voice input, and automatic linting/testing. Ideal for developers and solopreneurs who want AI-assisted coding directly in their terminal or IDE, for both new projects and existing codebases, typically used for code generation, refactoring, and debugging.
