In plain words
Next Sandbox is a browser-based tool that launches Linux containers in approximately two seconds. It allows users to run containerized Linux environments directly from their web browser without requiring local installation or setup. The product is designed for developers, learners, and anyone needing quick access to a Linux environment for testing, learning, or development purposes. It eliminates the traditional barriers to container experimentation by providing instant, accessible Linux container access.

It was a big challenge to run most of Node.js packages in browser, fast moreover. Virtual File system, resolve import/export. I got cold many times, depressions, burned out, yet still alive and finished it. Many guys helped me with an advice. Many users give a lot of positive feedback. There are 200,000 monthly unique users. I work full time now because of the freemium business model. To be honest - I am happy after many years of hard work.
