Aider is a free, open-source AI coding assistant that runs in your terminal and edits your local git repo via chat. With 48,897 GitHub stars and active daily commits as of September 2026, it's genuinely one of the most-used tools in this category, not just well-marketed.
Aider bills itself as "AI pair programming in your terminal" — edit code in your local git repo via natural-language chat, with automatic commits as it goes.
As of 2026-09-11, the GitHub repo has 48,897 stars, 4,945 forks, and 1,860 open issues, with a commit as recent as today — an actively maintained project, not an abandoned one. A "Show HN" post reached 432 points and 156 comments, one of the stronger developer-community receptions in this space. It's also a real, installable PyPI package (aider-chat, currently v0.86.2), not just a GitHub demo.
The star count, active commit history, and the size of its Hacker News reception all point the same direction: this is one of the more established open-source AI coding CLIs, not a weekend project. Terminal-first workflow won't suit everyone — if you want an IDE panel, look elsewhere — but for the audience it's built for, the numbers back up the hype.

Is Aider free?
Aider itself is free and open source (Apache 2.0 license). You still pay for whichever AI model API you connect it to (e.g. Claude or GPT), unless you use a free/local model.
Does Aider work outside the terminal?
Aider is CLI-first — there's no official full IDE panel. It does integrate with git directly and can be run alongside any editor.
