 A diff viewer that gives you sharable diff view links but does not store your data.

 ## :bangbang: No data sent to server
-You can take a look at the source code itself. All your data is kept as hash fragment in URL which never makes its way to server. Totally avoiding man in middle and XSS attacks to steal your data or any data breach. The data always stays in your URL and browser and never makes its way on the wire. Thats the main motive behind developing this tool. More about reasoning, why and how can be found in [Motivation](#motivation) section below.
