Gitignore generator

A precise .gitignore keeps generated artifacts, local env files and editor noise out of version control.

Commit shared editor configs intentionally (for example, recommended extensions) and ignore personal settings.

1. Pick the language, framework, OS and editor templates that match your project.
2. The tool merges them and removes duplicate patterns so the output stays clean.
3. Copy the result into a .gitignore at your repository root.

Order matters in Git: a later !pattern can re-include a file an earlier rule excluded, which is how you ignore a whole folder but keep one file in it.

.gitignore only affects untracked files — if a secret or build artifact is already committed, adding it to the ignore file does nothing until you run git rm --cached. Trailing slashes match directories only, and a leading slash anchors a pattern to the repo root. The file is assembled locally in your browser; your template choices are never uploaded.

Use this tool for quick browser-based work when you need an answer or output immediately. Use a dedicated application or automated workflow when you need bulk processing, approvals, or repeatable production rules.
