GitHub User Search Export

This GitHub automation can be used without being authenticated. But for email addresses to be displayed, you'll need to be logged in:
This automation will connect to the website on your behalf. The safest and most efficient way for PhantomBuster to authenticate as yourself is by using your session cookies. To make that process as easy as possible you can use PhantomBuster's browser extension. It's a 2-click installation.

Get it for Chrome

Get it for Firefox

If you're operating from another browser and/or want to do it manually, here is how to do it.

Go to GitHub and do a search. Here is the top JS dev (more than 50 followers) from Iceland:
https://github.com/search?utf8=%E2%9C%93&q=stars%3A%3E1000+extension%3Arb+location%3AIceland&l=JavaScript Either specify in one GitHub search or fill a Google spreadsheet with multiple searches' URLs.

If you chose the latter, don't forget to make it public.

And paste that spreadsheet URL back to PhantomBuster.

Automation always produces better results in the long run. Set the Phantom to launch repeatedly and get results while you're away!

This Phantom runs from the cloud, which means you don't even need to have your browser open or computer on for these launches to happen.

For more automatic launch options, click on the three little dots in the top right and "Show advanced settings."
