How to find websites using old framework?

[Liberty4All]

Hello everyone.
I am trying to find a way to scrape Google Search or Google Maps and find websites built on old framework such as:
ASP.NET
Classic ASP
PHP
Perl
JSP
Ruby on Rails
Adobe Flash
Wicket
..
Any idea on how to go about finding these websites?

Search for the file extensions.

Thanks guys.
Is there a scraper for this or must I do this manually on Google Search?

I am sure someone can make you a scraper but there must be some google scraping tools out there. I also think bright data and Oxylabs have services you can use.

What are you trying to do btw?

You could try using specific search operators on Google to look for tech stacks. Also, some online tools can detect what a site is built on, like Wappalyzer

You can use the "Powered by ASP.NET" search operator

You can build parser on Browser Automation Studio (free) or use A-parser (paid) to scrape all data you want.
Also you can hire freelancer on fivver, they will do all the rest.
