Hey! Rivet includes a library for running untrusted user code called agentOS: https://rivet.dev/agentos/
It provides Linux-compatible sandboxing using V8 / WebAssembly. Supports full POSIX filesystems, networking stacks, and process trees. Security-wise, it's the same model as Cloudflare Workers & Chromium.
