Aider

Aider

Aider lets you pair program with LLMs to start a new project or build on your existing codebase. It works best with Claude 3.7 Sonnet, DeepSeek, and OpenAI models, but can connect to almost any LLM including local models. It maps your codebase, integrates with Git for automatic commits, supports 100+ programming languages, and can be used from within your IDE or terminal.

Is Aider free to self-host?

Yes — it is open source and runs on your own hardware.

Does Aider need a lot of resources?

A server with 1–2GB RAM is enough for most workloads.

How do I deploy Aider?

Easiest via Docker — see the installation guide for commands.

Where does my data go?

Nowhere — everything is processed locally on your server.
