What is Aider?
Aider.ai is an open-source AI-powered coding assistant that allows developers to collaborate with large language models like GPT-4 directly from the command line. It integrates seamlessly with Git, enabling conversational programming, code editing, and refactoring within your existing development workflow. With Aider, you can modify multiple files at once, get code explanations, and maintain clean version history—all from your terminal.
Who can use Aider & how?
  • Solo Developers: Collaborate with an AI assistant to write, refactor, and understand code faster.
  • Backend & Full-Stack Engineers: Make structural changes across multiple files with Git-tracked AI assistance.
  • Open Source Maintainers: Use conversational Git-backed AI to manage contributions and improve large codebases.
  • Terminal-Centric Programmers: Benefit from CLI-native AI coding without switching to external apps.
  • AI Enthusiasts & Tinkerers: Explore open-source AI coding tools with full customization and transparency.

How to Use Aider.ai?

  • Install Aider via CLI: Use pip install aider-chat to install the tool and launch it from your terminal.
  • Connect to Your Codebase: Initialize Aider in a Git-tracked project and choose which files to work on.
  • Chat with the AI: Describe your coding needs in plain English, and Aider will make the changes.
  • Track Changes with Git: Aider commits every change it makes, so you can review and revert easily.
  • Refine & Continue: Iterate with the AI through conversational prompts to refine your code further.
What's so unique or special about Aider?
  • Terminal-Native Workflow: Aider works entirely in your command line—no IDEs or browser tools needed.
  • Conversational Coding: Collaborate with GPT-4 using natural language to modify and generate code.
  • Multi-File Edits with Git: Make changes across multiple files while automatically tracking everything in Git.
  • Context-Aware AI: The assistant reads and writes actual code from your selected files, not just guesses.
  • Open-Source & Customizable: Fully open-source and modifiable, giving you control over how it works.
Things We Like
  • Seamless Git Integration: Tracks all changes, commits automatically, and keeps your workflow clean.
  • Full Terminal Support: No GUI needed—ideal for CLI-first developers and power users.
  • Open Source: Transparent and customizable for any development environment.
  • Multi-File Editing: AI can understand and update code across multiple files in one session.
Things We Don't Like
  • Requires Git & CLI Familiarity: Beginners unfamiliar with the terminal might face a learning curve.
  • No Visual Interface: No GUI support may limit appeal to IDE-centric developers.
  • Limited Language Support for Some Features: Best performance with mainstream programming languages.
