FAQ about Aider

QWhat is Aider?

Aider is a terminal-based AI pair programming tool that lets developers collaborate with large language models through natural language to generate, modify, and refactor code, with deep Git version control integration.

QWhich programming languages does Aider support?

Aider supports 100+ languages including Python, JavaScript, TypeScript, Rust, Go, C++, Java, PHP, HTML, CSS.

QDo I have to pay to use Aider?

Aider is open-source, but using its AI features typically requires access to third-party language model APIs (such as OpenAI, Claude), which may incur fees. The tool also supports free options via OpenRouter or Google Gemini (may have daily limits).

QHow does Aider integrate with Git?

Aider deeply integrates with Git, automatically generating descriptive commits after each file edit, supports viewing changes via /diff, undo via /undo, and auto-committing in-progress work to prevent loss before edits are staged.

QWhich AI models does Aider support?

Aider broadly supports cloud and local models, including Claude 3.7 Sonnet, DeepSeek R1 & Chat V3, OpenAI o1/o3-mini/GPT-4o, Gemini 2.5 Pro, and also supports connecting to local models via Ollama or OpenAI-compatible APIs.

QHow does Aider handle my code and privacy?

Aider runs in your local terminal; code processing typically happens in your local environment. When using cloud AI models, code content is sent to the provider's API. Please review the provider's data handling policies.

QHow do I install and start using Aider?

Install via pip, pipx, uv, or Docker; requires Python 3.9+ and Git. After installation, start in a Git project directory, add files with /add, and describe your needs in natural language to begin coding.

QHow is Aider different from IDEs like Cursor?

Aider is a terminal-first, lightweight tool that emphasizes file-level precise control and deep Git integration for flexible collaboration and scripting. Cursor and similar tools offer full IDE integration with more precise code-block awareness.

QCan Aider handle multi-file projects?

Yes. Aider can work across multiple files in a project and understand the project structure via codebase mapping, enabling cross-file intelligent analysis and collaborative editing.
