Public evidence
Each finding includes its signal source and a plain-language evidence summary.
Free public technology checker
StackCheck examines public homepage signals to identify commerce platforms, analytics, payments, marketing, support and infrastructure technologies.
Run a lookup
We fetch only the public homepage, inspect a bounded response and label the evidence behind every detection.
Public technology report
Detections are based on public HTML and HTTP response headers observed at lookup time. They do not confirm contracts, private integrations, server-side systems or current commercial relationships. A technology not detected may still be used elsewhere on the website.
Designed for commerce operators
Each finding includes its signal source and a plain-language evidence summary.
We prioritise storefront, payment, retention, analytics, support and delivery technologies.
StackCheck visits a public homepage. It does not log in, bypass access controls or collect visitor identities.
