NexusPIPE vs reCAPTCHA
Head-to-head usage across the sites we track.
Detections for NexusPIPE end in Feb 2024. 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.
