Vpod – Tiny Linux sandbox running in WASM

Vpod is a developer tool that runs a tiny Linux sandbox (Alpine Linux) inside WebAssembly by emulating RISC-V, enabling instant, zero-setup sandbox environments directly in the browser or any WASM runtime. It’s designed for developers who need lightweight, portable isolation for testing or running code without relying on containers, VMs, or host subsystems. Its novelty lies in combining a full RISC-V spec implementation with WASM to deliver unprecedented portability and speed for sandboxed Linux execution.
