All 206 Dependencies
Every package CodeSandbox depends on, ranked by repo health score.
CodeSandbox is an online IDE that gives developers a fully-featured development environment in the browser, with no local setup required. It supports React, Vue, Svelte, Angular, and Preact through pre-configured templates, and lets you start coding, testing, or prototyping in seconds.
At its core, CodeSandbox runs a complete module resolution and transpilation pipeline inside the browser using its open-source `sandpack-core` engine. This means npm dependencies are fetched and bundled client-side, with caching via IndexedDB and HMR support — capabilities that normally require a Node.js server. The sandbox execution runs inside a sandboxed iframe communicating with the editor through a typed message protocol, keeping untrusted code fully isolated.
CodeSandbox supports GitHub repository import, converting any repo URL into a live environment within seconds. For teams and organizations, it offers real-time collaboration, branching, and a dashboard for managing shared sandboxes. The `react-embed` package allows developers to embed live, interactive sandboxes directly in documentation or blog posts.
The cloud-hosted platform at codesandbox.io adds microVM-based environments, Dev Container support, and a programmatic SDK for AI agent integration and scalable code evaluation. The open-source client repository provides the full web application, editor, and execution engine, making it possible to understand and contribute to the entire stack.
