JSFiddle allows users to publicly save their code an uncapped number of times for free. Each version is saved online at the application’s website with an incremental numbered suffix. This allows users to re-access their saved code. Code saved on JSFiddle may also be edited into new versions, shared with other parties, and forked into a new line.
JSFiddle is widely used among web developers to share simple tests and demonstrations. JSFiddle is also widely used on Stack Overflow, the dominant question-answer online forum for the web industry.
In 2009, JSFiddle’s predecessor, MooShell, was created by Piotr Zalewa as a website application which was exclusive to the MooTools community. In 2010, Oskar Krawczyk joined the project as a developer, and the platform was made freely available under the name of JSFiddle.
In 2016, JSFiddle underwent a full platform overhaul and became ad-sponsored. In 2017, Michał Laskowski and Andrzej Kała joined the company.
