Generate a .gitignore file
Every project needs a .gitignore so build artifacts, dependencies and secrets stay out of version control, and the right entries depend on your stack. This generator produces a .gitignore for common stacks, Node, Python, PHP, Java, .NET, so you exclude the right files from the start.
Why the right ignores matter
Committing the wrong files causes real problems: a huge dependencies folder bloats the repository, a build output creates noisy diffs, and, worst, a committed secret or config file is exposed and stays in history. A stack-specific .gitignore excludes exactly the files that should never be tracked for that language and its tools, which is knowledge accumulated across many projects. Generating it means you do not have to remember every artifact directory and temp file your stack produces, and you avoid the costly mistake of committing something that should have been ignored.

It runs entirely in your browser, so nothing you paste is uploaded and the result is yours to copy straight into a project, which lets you work on private code and data without anything leaving your machine.

Frequently Asked Questions
What should a .gitignore exclude?
Dependencies, build artifacts, temporary files, and secrets or local config, the files that should never be in version control for your stack.
Which stacks does it cover?
Common ones like Node, Python, PHP, Java and .NET, each with the artifacts and directories specific to that language and its tools.
Why does committing the wrong files matter?
Because it bloats the repo, creates noisy diffs, and, worst, a committed secret is exposed and stays in the history even after deletion.
Can I combine stacks?
A project using several stacks needs the ignores for each; generate for your main stack and add others’ entries as needed.
Is my input uploaded?
No. The generation runs entirely in your browser.
