What does HackerNews think of wappalyzer?

Well, it seems like a good part of the analyzer is about some "leaks" or specific behaviors from a language that could give us some tells about what technology is used. I checked Wappalyzer's code (at least the last commit before it went private: https://github.com/dochne/wappalyzer) and PHP gives more tells (https://github.com/dochne/wappalyzer/blob/main/src/technolog...) than Python for example (https://github.com/dochne/wappalyzer/blob/main/src/technolog...).

Some technologies seem to give more tells than others. Which means some technologies could be way more invisible than others. I am not sure we can suppose the known and unknown technologies have the same ratio.

I quickly checked some websites with BuiltWith and Wappalyzer and from my personal totally unscientific and small sample data, they seem to detect more easily PHP than other languages like Python.

Again, I don't know. But I took 5% to be optimistic. It could be 30% or 50%. And then the whole picture changes.

Edit: Funny thing, it even adds PHP to some sites I know (almost for sure) don't use PHP. Like GitHub using Ruby (true) and PHP with Drupal (???).

Here is one I found with the last commit: https://github.com/dochne/wappalyzer
