.gitignore Generator
Build a .gitignore from templates.
About .gitignore Generator
A repository picks up junk the moment real work starts: node_modules on JavaScript projects, __pycache__ in Python, build folders, IDE settings, and operating system clutter such as .DS_Store. A .gitignore file tells git which paths to leave out, and writing one from memory is how secrets and gigabytes of dependencies end up in history. This generator assembles the file from curated templates per stack. Choose a stack, append its block, and repeat for every technology the project touches. Appending is safe to repeat: rules already present are skipped, so mixing Node, VS Code, and macOS blocks produces one clean file without duplicates. The result stays editable as plain text, because real projects always end up with a few project-specific entries.
How to Use .gitignore Generator
Pick a stack
Choose the primary technology from the dropdown, such as Node, Python, Flutter, Go, Rust, Laravel, Unity, or the IDE and OS blocks.
Append the block
Click Append to add that stack's rules under a labeled heading. Repeat for every stack the project uses. Rules already in the file are not added twice.
Add project-specific entries
Type directly into the text area for anything unique to the repo: local data folders, generated assets, or a config file with live credentials.
Save it to the repo root
Click Download to get a .gitignore file, place it at the repository root, and commit it. From then on git skips everything listed.
Why Use .gitignore Generator: Common Use Cases
Starting a new project
Drop in the right blocks in the first minute of a repo, so dependency folders and local secrets never enter git history in the first commit.
Cleaning up a messy repository
Discover that build output and editor settings are tracked, generate the proper blocks, and stop the noise from growing with every commit.
Adding a second technology to a project
A web frontend joined by a Python backend needs both ecosystems ignored. Append the second stack and the deduping keeps the file tidy.
Standardizing across a team
Generate one agreed file and commit it, so every clone ignores the same things and nobody commits a debug.log again. Audit what the repo should never track with Env Viewer.

Tips for .gitignore Generator
Ignoring a file does not untrack it. If a file was committed before the rule existed, remove it from the index with
git rm --cachedand then commit.A line starting with an exclamation mark re-includes a path that another rule ignored, which is how templates keep
.env.examplevisible while hiding.env.Put environment files on every project's ignore list on day one. Real credentials belong only in a local
.env, and Env Viewer helps audit one before sharing.Global ignores live outside the repo with
git config --global core.excludesfile, useful for personal editor droppings you never want in any project.Not sure what is being ignored and why? Run
git check-ignore -v pathin the repo and it names the exact rule and file responsible.
Frequently Asked Questions
Where should the .gitignore file live?
At the repository root for project-wide rules. Git also reads .gitignore files in subdirectories, which apply only to that folder, but most projects do fine with a single root file listing everything.
Why is a file still tracked after adding it to .gitignore?
The ignore list only affects untracked files. Git keeps following anything already committed, so run git rm --cached <file>, commit, and from that point the rule takes effect.
What is the difference between a leading slash and none?
A leading slash anchors the pattern to the directory containing the .gitignore, so /build ignores only the top-level build folder. Without the slash, build ignores any folder of that name anywhere in the tree.
Do I need the macOS and IDE blocks on every project?
They cost nothing and prevent the most common accidental commits: .DS_Store, Thumbs.db, and .idea folders. Teams usually include one OS block and one editor block regardless of stack.
Can I ignore a whole folder but keep one file in it?
Yes, with a pair of rules: ignore the folder, then add a negated rule for the file you want, such as !logs/keep-me.txt. Git needs the folder rule written so it still descends into the directory for the exception to work.
Is a bigger .gitignore slower?
Not noticeably at typical sizes. Repositories with hundreds of rules still evaluate ignores instantly, so a thorough file is a better trade than a minimal one that leaks a build folder.
