🙈 Gitignore Generator
Compose a .gitignore from 25+ language, framework, IDE, and OS templates with search, presets, and custom rules.
Why it is useful
It helps developers avoid committing build artifacts, secrets, OS junk, and IDE metadata.
How it works
Select templates or a stack preset; the browser merges unique rules and optional section comments.
Best input
Pick your primary language/runtime first, then OS and editor, then add project-specific custom rules.
Git tip
If a file is already tracked, untrack it with git rm --cached before relying on .gitignore.
Privacy note
Template generation happens locally in your browser.
Important limitation
.gitignore cannot scrub secrets already committed to history.
Quick answers
Why is my file still tracked?
Ignoring only affects untracked files. Remove cached tracked files first.
Can I use this as a global gitignore?
Yes — enable global-style comments and put the file at the path configured by core.excludesFile.
Common Use Cases
Start a clean Node repository
Select Node, VS Code, macOS, and env templates so a new repo ignores modules, IDE junk, and secrets from day one.
Bootstrap a Node monorepo ignore file
Select Node, Astro/Next, VS Code, macOS, and env templates, then add workspace-specific dist folders.
Python + Jupyter project
Combine Python, Jupyter, pytest, and macOS templates for a data-science repo.
Docker-heavy backend
Use Go/Rust/Java plus Docker and JetBrains templates for backend services.
