Overview of Aider

Aider is an open-source AI pair programming tool built for developers who prefer the terminal. It connects to your local git repository, maps the codebase, and helps edit files across languages such as Python, JavaScript, TypeScript, Rust, Go, Ruby, PHP, HTML, CSS, and more. The product is strongest when a developer wants a focused coding loop instead of a full AI IDE. You can ask Aider to explain files, make changes, fix bugs, write tests, update docs, and commit work back to git, while still keeping control of the project locally. Aider works with many model providers and can connect through OpenAI-compatible APIs, OpenRouter, Anthropic, Gemini, Ollama, GitHub Copilot, and other supported routes. That flexibility makes it attractive for developers who want to experiment with different models without changing their coding workflow. For FutureStack, Aider belongs in Coding because it targets a very specific high-intent workflow: terminal-based AI code editing. It is best for technical users who are comfortable with command-line tools and want an open-source alternative to IDE-heavy coding agents.
