There ought to be an open source version of this. Wondering if it's "just" compiling the respective binaries needed by the tool chain (node, esbuild, who knows what else) to WebAssembly and providing proxied network access (for the registry). Alternatively, wondering if this could work with the various linux-on-a-webpage demos that were recently posted here.
