Getting Started

Here's an online demo and a small getting started guide:

LIVE DEMO

Status

wasm3 passes the WebAssembly spec testsuite and is able to run many WASI apps.

Minimum useful system requirements: ~64Kb for code and ~10Kb RAM

wasm3 runs on a wide range of architectures (x86, x86_64, ARM, RISC-V, PowerPC, MIPS, Xtensa, ARC32, ...) and platforms:

  • Linux,
    Windows,
    OS X,
    FreeBSD
  • Android,
    iOS
  • OpenWRT-enabled routers
  • Raspberry Pi, Orange Pi and other SBCs
  • MCUs: Arduino, ESP8266, ESP32, Particle, ... see full list
  • Browsers... yes, using WebAssembly itself!
  • wasm3 can execute wasm3 (self-hosting)

Advanced features and post-mvp proposals support

☑ Sign-extension operators
☑ Non-trapping float-to-int conversions
☑ Structured execution tracing
☑ Self-hosting
☑ Gas metering
☐ Multi-value
☐ Bulk memory operations
☐ Reference types
☐ Tail call optimization
☐ Fixed-width SIMD

Installation

Please follow the installation instructions.
Wasm3 can be used as a library for:

Python3
C/C++
GoLang
Rust
Swift
Arduino, PlatformIO, Particle

Motivation

Why use a "slow interpreter" versus a "fast JIT"?

In many situations, speed is not the main concern. Runtime executable size, code density, memory usage, startup latency can be all improved with the interpreter approach. Portability and security are much easier to achieve and maintain. Additionally, development impedance is much lower. A simple library like Wasm3 is easy to compile and integrate into an existing project. (Wasm3 builds in a just few seconds). Finally, on some platforms (i.e. iOS and WebAssembly itself) you can't generate executable code pages in runtime, so JIT is unavailable.

Why would you want to run WASM on microcontrollers?

Wasm3 started as a research project and remains so by many means. Evaluating the engine in different environments is part of the research. Given that we have Lua, JS, Python, Lisp, ... running on MCUs, WebAssembly is actually a promising alternative. It provides toolchain decoupling as well as a completely sandboxed, well-defined, predictable environment. Among practical use cases we can list edge computing, scripting, running IoT rules, smart contracts, etc.
