About Fiddle

Electron Fiddle lets you create and play with small Electron experiments. It greets you with a quick-start template after opening – change a few things, choose the version of Electron you want to run it with, and play around. Then, save your Fiddle either as a GitHub Gist or to a local folder. Once published on GitHub, anyone can quickly try your Fiddle out by just entering it in the address bar.
