Hello HN community, I am very happy to share with you BrowserPod for Node.js - a sandboxed Node runtime, compiled to WebAssembly, that runs completely in the your browser.

BrowserPod builds on our previous work on WebAssembly virtualization, see WebVM (https://webvm.io) as an example. The environment is not a simple set of shims, but the "real" Node.js, including support for filesystem, multiple processes and outbound and inbound networking.

This latest feature is powered by "Portals", shareable public URLs that let any user you want, anywhere on the internet, access full-stack applications running locally in your browser. Portals can be used to power live demos of full-stack frameworks, previewing what you (or your agent) are building and sharing the state of your app with testers, colleagues or customers.

Node.js is just the first "engine" of BrowserPod. Behind the scenes there is a real WebAssembly kernel and we are soon going to support more languages, with Python, Ruby, Go and Rust coming first in our pipeline.

Later in the year we expect to merge back our previous work on x86 virtualization into BrowserPod, and be able to run arbitrary binary containers safely sandboxed in the browser.

Let us know what you think.
