Lunatic is an Erlang-inspired runtime for WebAssembly that provides super lightweight, sandboxed processes for building fast, fault-tolerant, and scalable server-side applications. It can run code from any language that compiles to WebAssembly, with Rust and AssemblyScript libraries currently available.

Use cases

• run webassembly modules on the server
• build massively concurrent backend services
• run untrusted code in a sandboxed environment
• create distributed clusters of nodes
• build fault-tolerant services with supervision trees
• handle many concurrent http or websocket connections
• run c code safely in isolation

When to choose

• you need Erlang-style fault tolerance and massive concurrency with WebAssembly sandboxing
• you want to run untrusted or crash-prone code in isolated processes
• you want a portable compile-once runtime across architectures and operating systems
• you want to build distributed clusters with secure QUIC/mTLS connections

When to avoid

• you need a mature production runtime with a large ecosystem like Erlang/OTP, Go, or Node.js
• your language does not compile to WebAssembly
• you need hot reloading, which is not yet supported
• you depend on libraries beyond the Rust and AssemblyScript bindings
