Wasm3
A fast and universal WebAssembly interpreter designed for portability, minimal footprint, and broad platform support.
What is Wasm3?
Wasm3 is a fast, standards-compliant WebAssembly interpreter and runtime designed for portability and minimal resource usage. It solves the problem of running WebAssembly code in environments where Just-In-Time (JIT) compilation is impractical or impossible, such as embedded systems, iOS, and browsers. The project prioritizes ease of integration, security through sandboxed execution, and broad compatibility across diverse hardware and software platforms.
Developers and engineers working on embedded systems, IoT devices, mobile applications (especially iOS), and edge computing platforms that require a lightweight, secure WebAssembly runtime. It also targets those needing to integrate WebAssembly into existing projects via extensive language bindings, including Python, Rust, C/C++, Go, Swift, and .NET.
Developers choose Wasm3 over alternatives for its exceptional portability across a wide range of architectures and operating systems, its minimal footprint (requiring only about 64KB of code space and 10KB of RAM), and its focus on security and ease of integration. Unlike JIT-based runtimes, it provides predictable performance and is usable on platforms that restrict dynamic code generation.
