Mock .gitignore Generator
Used by developers, writers, and creators worldwide.
A mock .gitignore generator produces an example .gitignore file for common project types. The .gitignore file tells Git which files and folders to leave untracked — dependencies, build output, secrets, and editor clutter — and getting it right early keeps a repository clean. This tool emits a sensible .gitignore for a Node, Python, or general project. Choose a stack and copy the file. It is ideal for starting a project, learning what to ignore, and documentation. The file groups the usual suspects with comments, so it is easy to read and extend. A crucial point: always ignore secrets like .env files, since committing credentials exposes them in your history forever, even if you delete them later. Adapt the list to your own toolchain, and add entries as you discover files that should not be tracked. A good .gitignore from the start saves a lot of cleanup later.

FAQ
what does .gitignore do
It tells Git which files and folders to leave untracked, so they are not committed — things like dependencies, build output, editor settings, and secrets. Keeping these out of the repository keeps it clean and avoids committing things that do not belong.
why is ignoring secrets important
Committing a secret like an .env file exposes credentials in your Git history permanently, even if you later delete the file. Ignoring secrets from the start prevents this. Always keep .env and credential files out of version control.
can i add to .gitignore later
Yes. You can extend it any time as you discover files that should not be tracked. Note that .gitignore only affects untracked files, so anything already committed must be removed from tracking separately before it is ignored.
