Best JSON Editors for Next.js

StackBlitz WebContainers deliver a browser-based Node.js environment that fundamentally changes what's possible in interactive developer experiences. They allow applications to run native package managers, build tools, and full-stack frameworks fully client-side with no server infrastructure required. Using the WebContainer API, teams can programmatically boot a container, populate its filesystem, install packages, and start dev servers inside the browser. This unlocks advanced use cases like interactive tutorials, live coding courses, in-app IDEs, low-code editors, and AI-powered tooling with runtime awareness. WebContainers work across major browsers, support Wasm out of the box, and provide strong security through sandboxed execution. Developers can offer disposable, fast, and isolated workspaces that scale instantly without backend costs. The technology already powers leading frameworks and education platforms, validating its stability and performance. With WebContainers, any app can embed a complete development environment to increase engagement, accelerate learning, and reduce friction in product workflows.

RunCode offers online workspaces that allow you to work in a web browser on code projects. These workspaces offer a complete development environment that includes a code editor, a terminal and access to a variety of tools and libraries. These workspaces are easy to use and can be set up on your own computer.
