What JSFiddle is

JSFiddle is a web-based playground and code hosting platform for creating and sharing frontend examples in HTML, CSS, JavaScript, React, and Tailwind. Its live editor separates HTML, JavaScript, and CSS panels from the rendered result. Listed starters include Preact, TypeScript, CoffeeScript, SCSS, CSS Grid, Bootstrap, and PostCSS. Users can add external libraries by searching CDNJS or entering a URL. Fiddles can be embedded on other pages with an iframe or script, with options for tabs, theme, and accent color. Documentation also describes loading examples from GitHub repositories and Gists, and displaying a fiddle from a POST request through its API without saving it on JSFiddle. A beta AI completion feature uses Mistral Codestral and requires users to supply their own API key. The free Basic plan provides the basic service. JSFiddle PRO costs €8 a month and includes private fiddles and collections, custom-domain Fiddle Pages, an ad-free editor and listing pages, and early feature access. A one-time 80.00 EUR option provides PRO features for one year.
