Lucet is a compiler and runtime that compiles WebAssembly modules ahead of time (AOT) to native code and runs them inside a sandbox. Fastly developed it for its edge computing platform and transferred it to the Bytecode Alliance, and it uses Cranelift for code generation. With very low instance creation cost, it was designed for creating an isolated execution environment per request, and development as a standalone project ended when it was merged into Wasmtime.
