Smart Deduplication
Merging multiple templates often creates duplicate rules. Our engine detects and removes exact duplicates and near-duplicates across every selected template before output.
Select your languages, frameworks, and IDEs — our smart generator combines GitHub-standard templates into one clean, deduplicated .gitignore file. No clutter. No duplicates. Just precision.
Not just a template copier — a smart generator that understands your project's actual needs.
Merging multiple templates often creates duplicate rules. Our engine detects and removes exact duplicates and near-duplicates across every selected template before output.
Covers languages, frontend & backend frameworks, package managers, popular IDEs, operating systems, and cloud platforms — all in GitHub's official pattern standard.
Append your own glob patterns — project secrets, local overrides, or company-specific directories — into a clearly labelled custom section at the bottom of the file.
Toggle section comments so each block is clearly attributed to its source template, making the file readable and maintainable months after you create it.
One-click download saves a properly named .gitignore file directly to your device — no copy-pasting into a text editor, no encoding issues.
The custom rules panel validates your patterns as you type — catching invalid syntax, blank negation patterns, and space-prefixed rules that Git silently ignores.
Switch to the Stats tab to see a full breakdown: total lines, rule count per template, duplicate patterns removed, and an estimated file size.
System-aware theme with a manual toggle that persists across sessions via localStorage — because developers have opinions about their editor background color.
Four steps from zero to a production-ready .gitignore file in your project root.
Pick your programming languages, frameworks, IDEs, and target operating systems from the categorized pill selectors.
Type any project-specific patterns in the Custom Rules panel — .env files, build artifacts, credentials, or local tooling configs.
Click Generate. The tool combines, deduplicates, and annotates every selected template into a clean live preview instantly.
Copy the content to your clipboard or download a ready-to-use .gitignore file and drop it into your project root.
Every software project accumulates files that should never reach a version control system. Compiled binaries, local environment variables, IDE workspace configs, package dependency folders like node_modules/ or __pycache__/ — these files are bulky, environment-specific, or actively dangerous to share. The .gitignore file is Git's mechanism for telling the version control system to look the other way. When you add a pattern to .gitignore, Git stops tracking matching files and directories entirely, keeping your commit history clean and your repository lightweight.
The GitHub gitignore collection, maintained at github.com/github/gitignore, is the community-accepted source of truth for these patterns. Each template is authored and reviewed by practitioners who know exactly which artifacts a given language or framework generates. Python developers need to exclude *.pyc, __pycache__/, .venv/ and dist/. Node.js projects accumulate node_modules/, .npm/, and various lock files. Compiled Java projects create *.class, *.jar, and Maven or Gradle build folders that can reach gigabytes in size. Our generator draws directly from these patterns, combining them intelligently so you never have to look up the right syntax yourself.
The gitignore folder concept is one area where developers often trip up. Adding a bare directory name like build to .gitignore will match both files and directories named build. Adding build/ with a trailing slash restricts the match to directories only, which is usually the safer and more explicit choice. The double-star glob pattern **/logs/ matches a gitignore directory named logs at any depth in the project tree — useful for monorepos and projects with nested packages. Understanding these nuances is what separates a well-crafted .gitignore from one that silently lets artifacts through.
One common misconception: a .gitignore file only prevents future tracking of untracked files. If you've already committed a file and later add it to .gitignore, Git will keep tracking it until you explicitly run git rm --cached <filename>. This is why having a solid .gitignore in place from day one of a project is far better than retrofitting one later. Starting with our generator ensures you cover the most common patterns for your chosen stack before the first commit.
For teams, a well-structured .gitignore is also a form of documentation. When a new developer clones the repository, the .gitignore tells them which generated directories exist, which build tools are in use, and which local configuration files they'll need to create themselves. Section comments in the file — which this generator includes by default — make that even clearer, attributing each block of rules to its relevant tool or framework. The result is a .gitignore file that's as readable as your source code.
build/ or dist/. This tells Git to skip the entire folder and its contents recursively. Use **/logs/ to ignore any directory named logs at any depth in the project. Our generator already uses these correct patterns for every framework template included.
# Custom Rules section at the bottom of the output file.
git rm --cached <file> to untrack it before the .gitignore rule takes effect. Our generated file includes a helpful reminder comment explaining this behaviour at the top of every output.
