SunOS vs Ubuntu
Head-to-head usage across the sites we track.
Detections for SunOS end in Nov 2025. 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.
