This used to be the best for finding out what was running behind a website, besides FOCA Pro, but now the new title is held by Wappalyzer, since WhatRuns has not been updated in 3 years.

Only works half of the time

It use to run well however now it only spins on most websites. I noticed that version in chrome extension store is higher. Maybe it's no longer maintained for firefox?

Could not be better. It seems almost too good to be true!

It usually doesn't work.

Did not work. Kept receiving the same data for every website - even after restarting MFF and PC.

Doesn't work all the time. If you want a more reliable tool, check out the "BuiltWith" extension by garazy.

Bad privacy: it creates a cookie every time you start firefox even if you do not use the addon, why? The code is not open source and the Terms (privacy) are pretty open: " agree to the use and collection of information... used by the company or any of its authorised partners": no thanks!

Only shows "Javascript Infovis Toolkit" in react

Cool extension, but is there a reason for such broad permissions? It seems a bit excessive to need such broad access. Also, would you guys consider making this open source?

Nice App! But it don't work very often and the results are wrong very often, too – e.g. the Version fo Wordpress is wrong. Critical Privacy!

very good, but the result is not always reliable
