About gitignore Generator

Generate comprehensive .gitignore files for any tech stack. gitignore Generator runs entirely in your browser — no installation, no uploads, and no data ever leaves your device.

Common use cases: bootstrap .gitignore for new projects quickly; add language-specific ignore rules to existing repos; combine rules for full-stack projects with multiple languages. Whether you are debugging, prototyping, or building production code, having a fast and private tool for this task saves time compared to writing one-off scripts or using an online tool that logs your data.

Like every tool in Catalyst, this one is free forever, requires no login, and is safe to use with confidential data. All processing happens client-side via native browser APIs.

Frequently asked questions

Is any data sent to a server?
