Counts include broader stored detections, without the public preview’s quality filters. Co-detection describes an observation, not a recommendation or integration guarantee.
By scanning headers, HTML, JS globals, meta tags, and cookies. Detection is automated and non-intrusive.
The average detector score for Yaws is 100/100. It measures matching evidence, not independently verified accuracy.
Yes. Pro and Business plans include CSV export with full filtering.
Observation dates are shown on each report. Refresh timing varies with crawler capacity; you can request a fresh scan from the dashboard.
Our database recorded a net change of 0 observations in 30 days. New coverage and rescans affect this number; it is not a measure of market growth or migrations.
A 0–100 detector score based on matching signals. Stronger evidence increases the score, but false positives and missed technologies remain possible.
