Calendly in Homepage Source

Calendly is a scheduling tool that embeds a booking widget so visitors self-serve a meeting slot; it is a common last step in B2B demo and sales funnels.

The source-code fingerprint

Inline and popup embeds load the widget from assets.calendly.com/assets/external/widget.js plus a matching stylesheet, so the assets.calendly.com host is in the page.

Likely false positives: Plain text links to calendly.com/<user> that open in a new tab don't load the widget asset, so those bookings are missed by this host fingerprint.

How this works

The headline distinguishes candidate upper bounds (index prefilter), estimated matches (a projection from checked samples) and verified matches (an exact count established by the engine). The index contains 131,219,565 homepage documents, one homepage per hostname, including subdomains. The source index was promoted 2026-09-22 and follows a quarterly rebuild schedule. The sample date is when this query was checked against the stored index, not a new crawl of each example site.
