Wasm3 is a fast WebAssembly interpreter and universal WASM runtime written in C, usable as a CLI tool or embedded library with bindings for many languages. It runs on platforms from microcontrollers to desktops and servers.
Use cases
- run webassembly modules on embedded devices
- embed a wasm interpreter in a c application
- sandbox untrusted code execution
- script iot devices with webassembly
- run wasm on the edge or in serverless environments
When to choose
- you need a small, portable, fast wasm interpreter for embedded or resource-constrained targets
- you want a universal runtime that builds almost anywhere with no dependencies
- you need sandboxed execution of wasm modules
When to avoid
- you need a high-performance JIT compiler for server-side wasm workloads
- you need cutting-edge wasm features or active new development, since the project is in minimal maintenance mode
