Every developer knows the frustration of accidentally pushing node_modules or .DS_Store to a shared repository. Handcrafting a .gitignore from scratch is tedious, and assembling patterns from disparate sources often leads to gaps—especially when a single project spans multiple languages, frameworks, and operating systems. The Gitignore Generator, one of 200+ free browser tools from DevTools, sidesteps that hassle by merging vetted templates into a clean, commit-ready file. No signup, no data leaving your machine: a privacy-first utility that does one thing well.
What it is
The Gitignore Generator is a straightforward web tool that creates tailored .gitignore files by layering ignore patterns from established templates. Instead of cobbling together snippets from blog posts or GitHub gists, you select the components of your tech stack—languages, editors, operating systems—and the tool combines their standard exclusions into a single, organized document. It pulls patterns from community-maintained sources, covering everything from dependency caches and build artifacts to OS-specific detritus. Duplicate entries are automatically removed, so you won’t encounter redundant lines or conflicting rules.
