Developer Workflow & Syntax Tips
If files were tracked before adding ignore rules, remove them from Git cache using git rm --cached <file>.

DotGitIgnore is a free .gitignore generator for software developers. It allows engineering teams to combine technology-specific templates across programming languages, web frameworks, IDEs, build systems, and operating systems into a single, cohesive, conflict-free configuration file.
What is a .gitignore file?
A .gitignore file tells Git which files and directories should not be tracked in version control. It prevents build outputs (dist/, target/), package caches (node_modules/, .venv/), local secrets (.env), and OS metadata (.DS_Store) from polluting commit logs.
Deterministic Deduplication
Unlike simple text concatenation, DotGitIgnore parses each template line-by-line. Exact duplicate rules are pruned automatically, rules are organized by stack priority (OS → IDE → Language → Framework → Tooling), and intentional negation rules (!) are preserved in their proper context.
Zero Tracking & Client-Side Execution
All template filtering, parsing, and merging execute 100% locally in your browser. No project source code, file paths, repository names, or environment configurations are ever transmitted to any remote server or third-party service.

DotGitIgnore catalogs over 320 verified configurations seeded directly from GitHub's authoritative github/gitignore repository and supplementary curated modern tooling:
How to Use Your Generated .gitignore
- Save to Repository Root: Download the file as
.gitignoreand place it in your root directory (e.g.~/my-project/.gitignore). - Stage and Commit: Add the ignore file to version control:
git add .gitignore && git commit -m "Add .gitignore". - Verify Rules: Test whether a specific file is ignored using Git's verification command:
git check-ignore -v path/to/file. - Fix Already-Tracked Files: If files were committed before adding your .gitignore, untrack them without deleting local data:
git rm --cached <file>.
