I tested some of my websites.

While I got accurate results for some projects, it showed completely wrong information about other projects...

E.g. it shows stuff with which I may experimented for one day but which isn't used on the project since multiple years anymore.

On the "Detailed Technology Profile" tab it shows first/last detected date and there's a tick box for "Hide Removed" on the right.

BuiltWith accuracy is pretty bad, however it's sufficient to understand what you need to
