gitignore-gen

A .gitignore file generator with 50+ built-in templates. Combine multiple templates, deduplicate patterns, and write the result to a file — all offline, with zero dependencies.

Features

• 50+ templates: Node, Python, Rust, Go, Java, PHP, Ruby, Swift, Kotlin, C, C++, Dart, Elixir, Haskell, Scala, R, Julia, Lua, Perl, TeX, Unity, Unreal, Android, Xcode, JetBrains, VSCode, Vim, Emacs, macOS, Windows, Linux, and more
• Smart merging: Combines templates with automatic deduplication and section headers
• Alias support: Use py for Python, js for Node, rs for Rust, etc.
• Search: Find templates by keyword
• Offline-first: All templates are embedded — no network requests
