.gitignore generator
This tool combines common operating-system, editor, language, and framework rules offline, preserves rule order and last-match semantics, and generates an editable .gitignore.
How to use the .gitignore generator
The selected templates and custom rules are combined only on the current page; the project directory is not read, and nothing is uploaded.
Search and select a template
Choose rules from operating system, editor, language, and framework templates that match the project’s actual environment.
Add custom rules
Add project-specific rules as needed, up to 100 KiB; the tool places custom content after the built-in template and preserves the rule order as-is.
Review and save
After checking that the generated result will not ignore necessary source code or configuration, copy the content or download the .gitignore.
Limitations and Notes
- The built-in templates are an original set of rules fixed by version and do not sync the latest templates from other sites online.
- The tool does not scan or infer your project structure, and it cannot determine whether a cache, build artifact, or key file should be ignored.
- .gitignore will not stop tracking files that have already been committed; once sensitive information enters history, it still needs to be cleaned up and rotated separately.
FAQ
Can multiple languages or frameworks be selected at the same time?
Yes. The template will be combined in the built-in order, custom rules will keep their full order and be placed at the end, to match the last-match-wins semantics of Git.
Why is the file still in Git after generation?
Files already tracked by Git are not affected by new ignore rules; confirm the risks before removing them from the index.
Is the template the same as the official GitHub template?
No. This site maintains an independent simplified template; review it against the project documentation and build process before use.
