Technology Lookup is a tool that you can use to identify what technology was used to build a website by simply entering its URL.
It's a very useful extension to see websites architecture details. I've run this extension to identify some websites and it shows the analytics, font scripts and more necessary information to be discovered. Furthermore, this extension is very easy to use so I suggest you to give it a try.
This is very helpful tools. I can verified the SSL and others metrics just only in a few second. It's highly recommended for SEO and developer team.
It's pretty good, you can find out what library a website uses, including its version 🤯
