Gitignore Generator
Build a .gitignore from templates for your stack, editor and OS.
One pattern per line. Lines starting with # are kept as comments.
Quick Tool Overview
The Gitignore Generator merges templates for your language, framework, editor and operating system into one labelled file, dropping every pattern the moment it has already been written — which is what pasting three gitignore files together never does.

About the Gitignore Generator
A .gitignore is one of those files that everyone copies from the last project and nobody quite reads. Pick the templates that match what you are building and this merges them into one file, with each section labelled so it stays maintainable.
The merge matters more than the templates do. Paste three gitignore files together by hand and you get `node_modules/` three times, a wall of comments for sections that contributed nothing, and no way to tell later which rule came from where. This drops a pattern the moment it has already been written, removes any section left with only its comments, and keeps the headings — so the result reads like a file somebody wrote rather than one somebody assembled.
Key features of the Gitignore Generator
Patterns de-duplicated
Node, React and Next all list node_modules/. It appears once, in the first section that claimed it, rather than three times.
Sections kept labelled
Each template becomes a named block, so in a year you can still tell which rule came from where and delete the ones that no longer apply.
Empty sections removed
A template whose every pattern was already covered contributes nothing, so its heading and comments are dropped instead of left as noise.
Judgement calls left open
Go’s vendor/ and CocoaPods’ Pods/ are included but commented out, because teams genuinely disagree and the file should not decide for you.
Forty templates
Twelve languages, nine frameworks, three operating systems, five editors and the build tools that litter a working tree.

Frequently asked questions
Because a repository belongs to everyone working on it, and your .idea/ or .vscode/ folder is yours. The usual alternative — a global gitignore on your own machine — works, but it does nothing for the next person who clones the project.
No, and this catches people out constantly. Git only ignores files it is not already tracking. Run `git rm --cached path/to/file` first, then commit; the ignore rule takes over from there.
For an application, yes — package-lock.json, composer.lock and Cargo.lock are how you get the same dependency tree in production as on your laptop. For a published library, leave Cargo.lock out so consumers resolve their own versions.
Where the right answer depends on your project. `vendor/` in Go and `Pods/` in CocoaPods are both committed by some teams and ignored by others, so those lines are present but disabled rather than decided for you.
