About JSFiddle

JSFiddle is a browser-based code playground where developers try out HTML, CSS and JavaScript, and its current homepage also names React and Tailwind. Snippets, called fiddles, can be run instantly and shared by link, which makes the service popular for demos, bug reproductions and quick experiments.

The free service is supported by advertising and asks visitors to allow it in their content blocker. A paid tier called JSFiddle PRO removes ads in the editor and listing pages and adds private fiddles and private collections, collections for organizing fiddles, and early access to new features. Fiddle Pages let a fiddle be served from a custom domain and vanity path, offering simple hosting for a personal project.

JSFiddle is a hosted proprietary service with no self-hosted version. PRO can be bought monthly or as a one-time purchase covering a year.
