.gitignore Generator — free online

Starting a new project and not sure what to keep out of Git? You don't want node_modules, build folders, or those little .DS_Store files cluttering your commits. Copying an old .gitignore and hoping it fits is a guess. We added a free tool that does it for you — .gitignore Generator — right in your browser.

What it does

You pick the languages, operating systems and editors you actually use, and it gives you a clean .gitignore back. The rules are merged and deduplicated, so you don't get the same line twice or leftover entries you don't need.

Nothing leaves your device

The whole thing runs in your browser. Your choices and the file it builds stay on your computer — nothing is uploaded anywhere, and nothing is saved on a server.

How to use it

1. Open .gitignore Generator and tick the languages, operating systems and editors you're working with.
2. The .gitignore updates as you go, with duplicate rules already removed.
3. Copy or download the file and drop it into your project.

It's free with no limit. There are more small tools on the Apps page.
