Show HN: QuickBEAM – run JavaScript as supervised Erlang/OTP processes

QuickBEAM is a JavaScript runtime embedded inside the Erlang/OTP VM.

If you’re building a full-stack app, JavaScript tends to leak in anyway — frontend, SSR, or third-party code.

QuickBEAM runs that JavaScript inside OTP supervision trees.

Each runtime is a process with a Beam global that can: - call Elixir code - send/receive messages - spawn and monitor processes - inspect runtime/system state It also provides browser-style APIs backed by OTP/native primitives (fetch, WebSocket, Worker, BroadcastChannel, localStorage, native DOM, etc.).

This makes it usable for: - SSR - sandboxed user code - per-connection state - backend JS with direct OTP interop Notable bits: - JS runtimes are supervised and restartable - sandboxing with memory/reduction limits and API control - native DOM that Erlang can read directly (no string rendering step) - no JSON boundary between JS and Erlang - built-in TypeScript, npm support, and native addons QuickBEAM is part of Elixir Volt — a full-stack frontend toolchain built on Erlang/OTP with no Node.js.

Still early, feedback welcome.
