WAVM is a WebAssembly virtual machine designed for non-browser applications, using LLVM to JIT-compile WebAssembly to near-native machine code. It supports WebAssembly 1.0 plus extensions like WASI, SIMD, threads, and exception handling, with sandboxing to isolate untrusted code.
Use cases
- run webassembly modules outside the browser
- embed a wasm runtime in a native application
- sandbox untrusted code with webassembly
- execute WASI programs on the command line
- jit compile wasm to native code with llvm
When to choose
- you need a fast, near-native WebAssembly runtime for server or embedded host applications
- you want WASI, SIMD, threads, or exception-handling support in a standalone VM
- you need to safely isolate plugin code inside a C++ application
When to avoid
- you only need WebAssembly in a web browser
- you require strong protection against side-channel attacks like Spectre
- you need a 32-bit host runtime
- you need a lightweight interpreter rather than a JIT with an LLVM dependency
