.gitignore Generator: Free, No Sign-Up Tool

This free gitignore generator builds a ready-to-use .gitignore file from more than 60 technology templates, including Node.js, Python, Laravel, Unity and Docker. Pick your stack, add optional custom rules, then copy the result or download it as a .gitignore file. It is made for developers who want a clean first commit.

What Is a .gitignore File?

A .gitignore file is a plain text file that tells Git which files and folders to leave out of version control. Each line is a pattern, and Git skips any untracked file that matches one. Typical targets are dependency folders, build output, logs, editor settings and files that hold passwords or API keys.

Keeping these files out of your repository makes commits smaller, reviews easier and clones faster. It also protects you from publishing secrets by accident.

Pattern basics

• * matches any characters inside a single file or folder name, so *.log ignores every log file.
• ** matches across folders, so **/temp matches a temp folder at any depth.
• A / at the end matches folders only, so build/ ignores a folder but not a file named build.
• A line starting with # is a comment.
• A line starting with ! is an exception that makes a path visible again. When two patterns conflict, the later line wins.

How to Use the .gitignore Generator

You can build a complete file in under a minute by choosing templates, setting a few optional rules and copying the output. Here are the steps.

1. Under 1. Select technologies, type in the search box (for example Node, Python, Laravel, Unity or Xcode) and click a template to add it. Chosen templates appear as tags. Use Clear to start over.
2. Open 2. Advanced rules (optional) if you want more control.
3. Type a Header comment (top of file), such as a project name and year, to label the file.
4. Under Extra files / folders to IGNORE, add your own patterns, one per line, such as backups/ or *.bak.
5. Under Force INCLUDE (override ignores), list files you want tracked even though a template ignores them, one per line.
6. Tick or untick the checkboxes for secrets, operating system files, editors, logs, archives and coverage output.
7. Click Generate .gitignore, check the result, then use Copy or Download .gitignore. Save the file in the root folder of your repository.

What Do the Checkbox Options Add?

Each checkbox appends a group of common patterns to your file, so you do not have to remember them. Two are on by default and four are off.

Worked Example: A React App With a Node API

Suppose you are starting a React front end with a Node.js back end on a Mac, using VS Code. You search for and click Node.js and React. In the advanced section you type Node and React app as the header, add backups/ to the ignore box, tick Add VS Code + JetBrains and enter .env.example in the force-include box.

After you click Generate .gitignore, the output starts with your header comment. Below it you get one labeled section per template, with entries such as node_modules/, dist/ and build/, followed by the operating system, editor and secrets groups and your own rules. The line counter above the output shows the total length.

Here is what that means in practice. The node_modules/ folder can hold thousands of files, and npm install rebuilds it, so it never belongs in Git. Your real .env stays private, while .env.example is force-included so teammates can see which variables the app needs.

How Do You Read and Act on the Result?

A good generated file is short, grouped by technology and free of patterns that hide source code. Scan it once before you commit.

What a good result looks like

• Dependency folders, build output, logs and secrets are all covered.
• Each template section has a comment line naming it, which makes later edits easy.
• Nothing ignored is something a new teammate would need to build the project.

What a poor result looks like, and the fix

• A source folder is ignored. Some templates ignore folders like lib/ or public/ because those are build targets in certain stacks. If yours holds real code, add a force-include line for it.
• A needed file is missing from Git. Check whether a wildcard such as *.log or a block option caught it, then add that file to Force INCLUDE.
• Too many unrelated rules. Remove templates you do not use. A Python project does not need the Unity template.

How Force INCLUDE works

Each line you add becomes an exception that starts with !, and the tool also reopens the parent folders so the exception can take effect. Git documents that you cannot re-include a file if one of its parent folders is excluded, which is why this matters. The side effect is that sibling files in those folders may become visible too, so read the output and check git status afterward.

Who Needs a .gitignore Generator?

Anyone who creates a repository benefits, because the first commit is where junk files usually slip in. These are common situations.

• New projects. Start every repo with a correct file instead of copying one from an old project.
• Multi-stack repos. Combine Node.js, Python, Docker and Terraform in one file when a single repository holds a front end, an API and infrastructure code.
• Game projects. Unity, Unreal Engine and Godot create large cache and build folders that should never be committed.
• WordPress and PHP sites. Ignore wp-config.php, uploads and cache folders so credentials and media stay out of the repo. If the site runs on Apache, an .htaccess redirect generator helps with the server side.
• Team onboarding. Add macOS, Windows and Linux defaults so nobody commits system files from their own machine.
• Cleaning up an old file. Generate a fresh version and compare it with your current one using a code diff tool to see what you are missing.

Best Practices and Troubleshooting

Most .gitignore problems come from timing and placement, not from the patterns themselves. Use the points below to avoid them.

Create the file before your first commit

Git only ignores files it is not already tracking. Add the .gitignore first, then run git add ., so build folders and secrets never enter the history.

Why is my .gitignore not working?

1. The file is already tracked. Run git rm --cached filename (add -r for a folder), commit, and the pattern will apply from then on.
2. The file name is wrong. It must be exactly .gitignore, not .gitignore.txt. Windows Explorer can hide extensions, so check the name in your editor.
3. The file is in the wrong place. Put it in the repository root, or in a subfolder if you want rules for that folder only.
4. The pattern is anchored. A leading slash, as in /build, matches only at the root, while build/ matches at any depth.
5. A later line overrides it. Run git check-ignore -v path/to/file to see which line decides the outcome.

Saving the file on Windows or in an editor

Use Download .gitignore and move the file into your project folder. Alternatively, create a new file named .gitignore in the root of your folder in VS Code or Visual Studio, paste the copied text and save.

If you committed a secret

Adding a pattern later does not erase history. If an .env file or key was already pushed, rotate that credential, because removing the file from the latest commit does not remove it from earlier ones.

Keep the file under review

Add a pattern whenever a tool starts producing new output, and commit .gitignore changes like any other code. The same habit applies to other config files you generate, such as CORS headers or a cron schedule.

Limitations to Keep in Mind

The generator produces a solid starting point, not a scan of your project. It does not read your repository, so it cannot know which folders hold your real code. It also cannot untrack files Git already follows.

Templates are broad on purpose. A few ignore dependency lock or resolved-version files, such as the Swift and Xcode template with Package.resolved. Whether you commit those depends on your team, so decide deliberately. For anything unusual in your build, add your own lines in the advanced rules.
