.gitignore Generator

Generate .gitignore files for any tech stack by selecting project types

What is it and how does it work?

A .gitignore generator builds the file that tells Git which files and folders to leave out of version control — by selecting your project types, you get a ready-made list of the patterns each one needs. A .gitignore prevents clutter and mistakes from entering your repository: build outputs, dependency folders like node_modules, editor settings, log files and, most importantly, secrets such as .env files that should never be committed. Each language, framework and tool has its own set of files to ignore, and remembering them all is exactly what this tool removes.

The reason a good .gitignore matters from the very first commit is that some mistakes are hard to undo. Once a huge dependency folder or a secret key is committed, it lives in the repository history even after you delete it, so getting the ignore rules right up front saves real trouble later. You pick the technologies you use — a language, a framework, an operating system, an editor — and the generator combines the standard patterns for each into one file. It runs in your browser, ready to copy into your project root.

Common use cases

• Starting a new project: generate a .gitignore for your stack before the first commit so build files and secrets are excluded from the start.
• Combining multiple tools: select a language, framework, OS and editor to get one file covering all of their generated files.
• Cleaning up a repo: produce the right ignore patterns to stop tracking files like node_modules or .env that slipped in.

Frequently asked questions

What should always go in a .gitignore?

Common essentials are dependency folders (like node_modules), build and output directories, log files, operating-system files (such as .DS_Store), editor and IDE settings, and — critically — secret files like .env. The exact list depends on your stack, which is what selecting project types assembles for you.

Does .gitignore remove files already committed?

No. .gitignore only stops Git from tracking files that are not yet tracked. A file already committed stays tracked even after you add it to .gitignore — you have to untrack it explicitly (for example with git rm --cached) for the ignore rule to take effect.

Why is it important to ignore .env and secret files?

Secret files hold credentials, API keys and passwords. Committing one exposes those secrets to anyone with repository access, and they remain in the history even if deleted later. Ignoring them from the first commit is the simplest way to keep secrets out of version control.

Can I combine patterns for several languages?

Yes — that is the point. A real project often mixes a language, a framework, an operating system and an editor, each with files to ignore. The generator merges the standard patterns for every type you select into a single, complete .gitignore.
