This list is geared toward input fuzzing and vulnerability discovery. It contains roughly 1.2 KB and pairs well with tools such as ffuf, wfuzz, burp, nuclei. Pick the smallest list that fits your engagement: shorter lists are faster and quieter for online attacks, while larger lists give broader coverage for offline work where speed is less of a constraint.

You can copy the sample preview straight from this page, copy the entire list to your clipboard, or download the raw .txt file. The full list is served directly from its upstream source on GitHub.
