Wondering what plugin this is..

Hey there guys,

You might have noticed that WpBeginner and Mashable both have a similar plugin which allows their readers to share the posts with real ease. Mashable have the plugin with more buttons than WpBeginner and I can’t help but feel that this isn’t a custom coded plugin, rather a commercial one.

Here’s a link to both. I’d really appreciate it if someone could point out to me what plugins they’re using, if they’re, in fact, different.

Here’s the mashable page.

Here’s the wpbeginner page.
