Audience
Teams building interactive devtools, coding education platforms, AI-assisted IDEs, or in-app developer experiences that require a secure, fast, and fully client-side Node.js runtime
About StackBlitz WebContainers
StackBlitz WebContainers bring a full Node.js runtime directly into the browser, enabling instant, secure, and interactive development environments inside any web app. Developers can run native npm, pnpm, and yarn at speeds up to 10× faster than local, without needing external servers. The API lets you boot containers, mount files, install dependencies, and run dev servers entirely client-side. WebContainers support major frameworks, Wasm workloads, and modern browsers, making them ideal for tutorials, sandboxes, docs, and AI-driven developer tools. With isolated, disposable environments, teams can offer a seamless coding experience that feels native and eliminates backend overhead. The result is a powerful platform that transforms web apps into full-featured IDEs.

JSFiddle
JSFiddle has the notion of panels (or tabs if you switch into the tabbed layout), there are 4 panels, 3 where you can enter code, and 1 to see the result: HTML - structure code, no need to add body doctype head, that's added automatically, CSS - styles. You can switch pre-pocessor to SCSS, JavaScript - behavior. There are many frameworks and code pre-processors you can use. Once you enter code, just hit "Run" in the top actions bar, and the fourth panel with results will appear. SFiddle allows you to switch the layout of the editor from the classic 2x2 grid to something that suits your needs. In addition to the grids mode it also has a tabbed mode. Grids are fully resizable. As an addition resizing the Results panel will tell you its width (handy for working on media queries).
