BrowserPod for Node.js runs untrusted code, such as that generated by AI agents, within an in-browser, sandboxed Node runtime called a Pod. Pods have high fidelity with native Node.js, and come with a virtual filesystem, multiprocess support, and Portals - public URLs for shareable previews. With BrowserPod, you can build agentic tools and web IDEs without server side compute. Node.js is the first runtime engine for BrowserPod, a language-agnostic, universal execution layer for the browser.
