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.
As the lead developer of BrowserPod I am very proud of this release. BrowserPod is truly the culmination of a decade of experience on browser-based compilers and virtual machines. I am looking forward to see what the community will build with BrowserPod.
Node.js is just the beginning. can't wait to make more and more Linux userland available in the browser
Hey Product Hunt - I’m Stefano, co-founder at Leaning Technologies.
Today we shipped BrowserPod for Node.js: a sandboxed Node runtime that runs inside the browser, so you can execute untrusted code (including AI-generated code) next to the user with low latency and strong data locality, without spinning up per-session cloud sandboxes.
A Pod is meant to feel like “real Node”: filesystem, multiprocess support, native tools and the ability to run real-world workloads including build pipelines and dev servers. One thing we’re especially proud of is Portals, shareable URLs that let you expose services running inside a Pod for live previews, interactive demos, and debugging with teammates.
Node.js is just the first engine. BrowserPod is built as a universal execution layer and we’ll be rolling out more runtimes next: Python, Rails, Go and Rust will all be supported by the summer. By the end of the year, BrowserPod will support running Linux containers!
If you’re building agentic tools, web IDEs, interactive docs, or anything that needs untrusted code execution, I’d love to hear from you! Let us know what you tried (and what broke!)
I wish I had this when I was learning. This looks like a nice way to iterate fast and experiment without worrying about crashing my machine or messing up my setup.
