@JonathanPLev the technology detection is tackled here https://github.com/HTTPArchive/wappalyzer

You'll be able to use the request URLs, as well as JS variables or DOM elements for detection.

Please move your detections there.

Unfortunately I'll have to close the PR in this repo.

@max-ostapenko is adding my metrics to that repo the same process as for this one? I don't see information on how to add to that repo in that ReadME.

alternatively, would I be able to adjust my detection or add some sort of other analysis that would qualify the detection for this repo?

Thank you!

@JonathanPLev here is a recent example of technology added: HTTPArchive/wappalyzer#136

I also notice that you use API endpoint URLs - these are usually used on the backend. There is also an argument against detecting such usage scenarios: #165 (comment)

There usually should be some JS library, or JS variable that help detect technology on the webpage. Please see the patterns supported for detection: https://github.com/HTTPArchive/wappalyzer?tab=readme-ov-file#patterns-optional
