Will adding a file to .gitignore stop tracking it if it's already committed?

No. Files already tracked by Git need to be untracked first with git rm --cached before .gitignore takes effect. The ignore file only applies to untracked files.

Can selecting multiple frameworks cause pattern conflicts?

Duplicate patterns are automatically deduplicated, so there are no conflicts. That said, it is a good idea to review the output to make sure no needed files are accidentally ignored.

Should I use a global gitignore or a project-level one?

OS and IDE patterns like .DS_Store or .idea/ typically go in the global gitignore (~/.gitignore_global), while build artifacts and dependency folders belong in the project-level .gitignore.

Add IDE patterns like .vscode, .idea, and .fleet
One-click copy and download of the generated file

How to Use

Search for or select your language and framework from the list
Optionally check OS and IDE pattern boxes
Review the generated .gitignore content in the preview panel
Copy to clipboard or download the file directly

Tips

Running frontend and backend in the same repo? Select both stacks at once
.env files and secret key paths are already included in the default patterns
After generating, you may still want to add project-specific paths like build/ or dist/
