Frequently asked questions

How does Glympt detect Leaflet?

By scanning headers, HTML, JS globals, meta tags, and cookies. Detection is automated and non-intrusive.

What does the score measure?

The average detector score for Leaflet is 99/100. It measures matching evidence, not independently verified accuracy.

Can I export?

Yes. Pro and Business plans include CSV export with full filtering.

Refresh rate?

Observation dates are shown on each report. Refresh timing varies with crawler capacity; you can request a fresh scan from the dashboard.

Does this measure Leaflet market growth?

Our database recorded a net change of 79 observations in 30 days. New coverage and rescans affect this number; it is not a measure of market growth or migrations.

What is "confidence"?

A 0–100 detector score based on matching signals. Stronger evidence increases the score, but false positives and missed technologies remain possible.
