Heap in Homepage Source

Heap is an autocapture product-analytics tool that records events without manual instrumentation.

The source-code fingerprint

The snippet initializes with heap.load("<appId>"), so the literal heap.load appears inline in the page.

Likely false positives: None significant.

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.
