About

CodePen is a social development environment for front-end designers and developers. Build and deploy a website, show off your work, build test cases to learn and debug, and find inspiration. Find inspiration from 1.8 million+ front-end designers and developers. Browse and share work from world-class designers and developers in the front-end community.

No more awkwardly finding alternate hosting for it, you can drag-and-drop it right onto CodePen and we'll host it for you. And not just images! CSS, JSON files, SVGs, media files, whatever! Projects is the most powerful feature of CodePen.

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.
