How to Find Almost Any GitHub User’s Email Address

Editor’s note: This was #1 on the Best of 2014 list.

GitHub can be a powerful tool for sourcing software engineering talent. For the uninitiated, GitHub is a software project hosting service on which software engineers create a profile, host their code, or contribute to other projects. GitHub profiles often include an email address, twitter handle, and/or link to a personal website. Due to this, and as previously posted on SourceCon, even a simple site: search on GitHub’s domain produces some serious results. However, some of the best profiles simply have no contact information aside from a (hopefully) real name and a GitHub username.

Traditionally, you may cross reference a GitHub profile with LinkedIn, run the username through namechk and see where else they hangout, or even try to deduce an email address with the Rapportive plugin. You may even go so far as to hunt them down on OKCupid. As it turns out, you can get almost any GitHub user’s email address directly through GitHub’s own API from the comfort of your own browser in five simple steps.

1. Copy and paste the next line into your browser (feel free to bookmark it):


2. Find the GitHub username for which you want the email:


3. Replace the xxxxxxx in the URL with the person’s GitHub username.


4. Hit Enter.

5. Press Ctrl+F and search for “email”.


According to GitHub, this information is publicly available. However, you would likely only see it if you were an Engineer committing code to your candidate’s public repository through the Git system. In essence, this works by calling up said public information through GitHub’s API in your browser.

While this method works for the vast majority of usernames, there are a few who have opted not to store their personal email address on their public repositories. However, of the many usernames used in testing this method, I only ran into 3 that were masked.

On a side note, if the user has a popular public repository you may return multiple email addresses belonging to the various contributors to the repository. You can clear through these by searching for the name on the account (such as “Fredrik”) instead of “email”. Although on second thought, you may wish to engage the other contributors as well.

  1. Matthew – nice! I love getting into code – just don’t have the time to do it these days. Kudos to all involved with the discovery – steve

  2. Thanks, Steve. Diving into the code is always fun but you’re right, it takes an insane amount of time. To be honest the original method I had required a person to navigate a unix command line or install a unix-style terminal in Windows, which for the average user is no simple feat.

    Glad you enjoyed it.

  3. This is great, nice find – let’s hope they don’t close this loophole the way LinkedIn did last year on with an API trick that used to let you view someone’s full profile regardless of degrees away!

    1. It works for me if I add a slash at the end of the URL. It has to be “…public/” and not “…public”

  4. Hey Guys! Its my duty to inform that apparently Github has modified this and its no longer available .. I know.. Bummer!


  5. Great Article Matthew. I’d just like to point out, for those who are not technically inclined, there are a number of apps already which are able to connect email addresses to social profiles – or the other way around. One example I know of is, and I believe they also report on GitHub accounts, as well as other popular social networks. There is also Rapportive – the Chrome Add-on, which is indispensable if you are a gmail user.

    1. I wonder which stupid person would pay 15$ per month for such a stupid plugin. You should read more about “open source” my friend.

    1. Hey Pavel,

      I may be wrong, but I think the whole idea of private email is like private repository. People should not be able to see your thing if it is private.
      According to, private email are not suppose to be expose to the public.
      Through the GitHub API, you could not get their private email which makes sense for security reason.

      I do not think anyone could get just anybody private email without some hacking.

      Hope this helps!
