Gitignore Generator
Pick your stack — Node, Python, Go, Rust, Java, Ruby, PHP, .NET, Swift, Kotlin, Dart/Flutter, Elixir, plus OS-level (macOS, Windows, Linux), editor-level (VS Code, IntelliJ, Sublime, Vim, Emacs), and framework- level templates (Next.js, Rails, Django, Laravel, Spring Boot, Unity) — and the tool assembles a clean, deduplicated .gitignore file ready to drop at the root of your repo.
Templates come from the canonical github/gitignore repository — the same lists GitHub itself offers in the "Add .gitignore" dropdown when you create a new repo. The improvement here is that you can pick MULTIPLE templates at once (e.g. Node + macOS + VS Code is the standard fullstack JS dev combo) and the tool merges them into a single ordered file with section headers, removing duplicate entries between templates so you don't end up with .DS_Store ignored 3 times.
Useful for spinning up new repos where you want comprehensive coverage from day one; retroactively fixing an old repo that's been accumulating committed build artifacts; cross-platform teams where Windows devs need Thumbs.db ignored and macOS devs need .DS_Store ignored. The output is just text — paste into .gitignore and commit.
Nasıl Kullanılır
- Click templates from the categories: Languages (Node, Python, Go, etc.), Operating Systems (macOS, Windows, Linux), Editors (VS Code, IntelliJ, Vim), Frameworks (Next.js, Rails, Unity).
- The combined preview updates live with section headers and deduplicated entries.
- Add custom rules at the top of the preview if you have project-specific paths to ignore (e.g. /tmp, /uploads, my_secret_config.json).
- Click Copy or Download .gitignore to save the result.
- Drop the file at the root of your repo, run `git rm -r --cached .` then `git add .` to force-clean any tracked files that should now be ignored.
Ne Zaman Kullanılır
- Initializing a new repo and you want comprehensive coverage from day one.
- Joining a team where everyone uses different OSes and editors — the combined .gitignore covers all the cruft.
- Cleaning up an old repo that has committed build artifacts you want to start ignoring.
- Setting up CI environments where you need to know exactly what's tracked vs ignored.
Ne Zaman Kullanılmaz
- When you have one specific path to ignore — just add a one-liner manually instead of generating a 200-line file.
- .gitignore for monorepos with mixed stacks — you'll need separate .gitignore files per subdirectory; this generates one combined file.
- Excluding files from a specific commit only — that's git-update-index --skip-worktree, not .gitignore.
Yaygın Kullanım Senaryoları
- Quick generation during a typical workday
- Pre-decision sanity-check on inputs and outputs
- Educational use — demonstrating the underlying concept
- Onboarding a colleague who needs the same calculation/conversion
Sık Sorulan Sorular
Why are some entries duplicated when I expected dedup?
True duplicates (the same exact pattern) are removed, but near-duplicates (e.g. *.log vs **/logs/*.log) intentionally aren't merged because they're not equivalent. The tool errs on the side of keeping more rules rather than aggressive deduplication that might silently drop coverage.
How do I un-track a file that's already committed?
Adding it to .gitignore won't help — git only ignores untracked files. Run `git rm --cached <path>` to untrack it (the file stays on disk, just not in git). Then commit. Now .gitignore will keep it out of future commits.
What about secrets — should I rely on .gitignore?
Use .gitignore for `.env` files and similar — but for actual secrets, also use a secret-management tool (1Password, AWS Secrets Manager, Doppler) and set up a pre-commit hook (gitleaks, ggshield) that scans for committed secrets. .gitignore is one layer; defense in depth wins.
Why are there separate Node and Yarn templates?
They overlap heavily but include some yarn-specific paths (.yarn/cache, .pnp.*) that the generic Node template doesn't. Pick both for projects using Yarn 2+ Plug'n'Play; just Node for npm or Yarn 1 classic.
How does the tool know about new entries when, say, Vite gets a new cache directory?
We sync periodically with the github/gitignore repo. New entries land within a release or two of upstream changes. If you spot a missing entry, manually add it to your .gitignore — and let us know via the contact page so we can update the template.
