h3fuzz — ffuf with HTTP/3 support and a web interface

h3fuzz is a fork of ffuf for discovering files and directories on web servers. The tool retains familiar wordlists, filters, and fuzzing options, while adding HTTP/3 support and a persistent web interface for managing scans. The tool automatically uses HTTP/3 when supported, falling back to HTTP/2 and then HTTP/1.1 when necessary.

Key features: • High speed — in the author's local benchmark, the tool exceeded 100,000 requests per second. • Scan management — launch multiple scans from the web interface, pause and resume them, rerun scans, and compare results. • Result analysis — search, sort, and filter findings. Scan sessions, settings, and results persist between runs.

Actual fuzzing speed depends on the network and the server's capabilities.
