Lucet is a native WebAssembly ahead-of-time compiler and runtime for safely executing untrusted Wasm programs inside applications, built on the Cranelift code generator. It has reached end-of-life and users should migrate to Wasmtime, which now includes all of Lucet's features.

Use cases

• run untrusted webassembly programs safely in my application
• aot compile wasm to native code
• sandbox wasm execution with low overhead
• embed a wasm runtime in a rust service
• compile wasi modules to native binaries

When to choose

• you are maintaining a legacy system already built on Lucet
• you need to study its AOT compilation and pooling allocator design

When to avoid

• starting any new project - use Wasmtime instead
• you need ongoing maintenance, security fixes, or new features
• you need pooling userfaultfd-based memory allocation, which Wasmtime now provides
