Datadome vs HTTP/3

Head-to-head usage across the sites we track.

Detections for Datadome end in Sep 2023. The fingerprint catalog behind our crawls no longer carries that technology as its own entry, usually because it was retired or split into more specific ones, so its figure is the last recorded and is not directly comparable with a currently tracked technology.
