.gitignore Generator

How to use it

1. Tick every language, framework or operating system your project touches.
2. The merged .gitignore builds below as you select, with duplicate lines removed and each section labeled by a comment.
3. Copy the result, or download it as a file named .gitignore.
4. Clear all selections and start over whenever you like.

Common use cases

• Starting a new repository - a sensible ignore file exists before the first commit instead of after the first accidental one.
• Polyglot monorepos - merge a JavaScript app, a Python service and editor folders into one consistent file.
• Cross-platform teams - include macOS, Windows and Linux noise files so nobody commits .DS_Store or Thumbs.db again.
• Onboarding - hand new contributors the same baseline ignore rules every machine should follow.

Why it stays private

Selection and merging happen entirely in the page. No repository is read, no file is uploaded - you paste nothing sensitive here at all.

FAQ

Q: Are the templates complete for each ecosystem? A: They cover the entries that cause the most accidental commits: build outputs, dependency folders, caches and OS noise. Specialized tools may add their own entries; append them after downloading.

Q: What does the deduplication do? A: Identical lines shared by several templates appear once. Negation lines like !keep/this are treated like any other line, so check the output when two templates disagree about the same folder.

Q: Can I suggest or edit templates? A: The built-in list is fixed inside the tool, but the output is plain text - edit it freely after copying.
