Made this after being frustrated with existing tools with similar functionality, which either do no adhere to the standard/do other weird stuff. Anybody have some feedback for functionality they feel are missing?

Still want to add:

-automatic generating hreflang elements

-make it a bit faster

-support for larger sitemaps.

-make it look nicer( I know almost nothing about making nice-looking software)

-add support for recieving a link to the results by e-mail when the crawling is done

Probably need to support SPA webapps, as they're very prevalent on the went today. Good work though!

4g wouldn't change the main thread issues.

Also, it's a mistake for developers to assume that everyone is on 4g, and that those on 4g are experiencing good speeds.

Even in London, if you're at a train station that's hit by delays, connectivity grinds to a halt as everyone starts looking for alternative transport.

In the big cities in India, 4g is pretty much always like that.

Where on earth do you live where 3G is "unrealistic?"

There are a fairly significant number of users without LTE. Bear in mind too that some of the names at the bottom of the list, like Brazil, are countries hosting a Grand Prix this year.
