Aider

v0.86.0 open-source
source ↗ rss ↗

Summary

Aider is an open-source command-line tool that lets a developer pair-program with an LLM directly in the terminal, editing an existing codebase or scaffolding a new one and committing the results to git as it goes. It connects to a wide range of cloud and local models, including current Claude, GPT-5, Gemini, and DeepSeek releases, so a developer can switch models mid-session rather than being locked to one provider. It builds a map of the repository to give the model context on large codebases, and it is aimed at individual developers and small teams who want AI-assisted changes tracked through normal git commits rather than pasted from a chat window. First committed in 2023, it has drawn 191 contributors and 108 commits in the past year, with its own release notes noting that Aider now writes most of its own new code.

What Aider answers

Which languages does the repository map understand beyond the mainstream ones?

it tags Fortran, Haskell, Julia, Zig, OCaml, MATLAB, and Clojure among others, so context-aware editing extends to less common codebases, not just JavaScript and Python

Do I have to touch configuration every time a new model comes out?

model aliases like sonnet, opus, gemini, and flash are kept pointed at the current release, so a session can move to a newer model without editing settings

What happens to my commit history when the AI makes the change?

each change lands as a normal git commit, with an option to add a co-author trailer identifying the AI's contribution

Can it work with files my repository is set up to ignore?

yes, files normally excluded by git can be explicitly added to its editing scope when needed

Is this still an actively maintained tool or a stalled project?

the most recent tracked release was 377 days ago against a history of 108 commits in the past year, so activity has slowed relative to its earlier pace

Will it keep working if I'm still on an older Python setup?

no, support for Python 3.9 has been dropped, so upgrading the runtime is required before adopting a current release

Features

3 capabilities · 3 backed by code, an API document or a real run

Built from everything we hold on Aider — every release we have summarised, its product documentation and how that documentation has changed, its README, its command-line surface and API, and runs we performed ourselves. Dates are when we first saw a capability, not when the vendor introduced it.
