C
C++
Java 8
Nodejs 6
Python 2

Install the extension.
On extension install, RunMyCode Online will open in a new tab and prompt you to authenticate to get a key.
On authenticating with any the of providers, you will be redirected to dashboard page and extension will be auto-configured with your key.
Now you can go to any supported language code page on Github or Gitlab and you will see a colored Run button added to left of usual action buttons (see screenshot). For example, you can test the extension with this Ruby code on Github
Clicking that Run button will open a runner where you can input any command line args and then press the big orange Run button to run the code on the page.
You can also edit the code using the web editor on Github or Gitlab and make it run through the same Run button as above.
