MEET WASINIX A growing world of WASIX builds

Your code.
Unbound.

The power of POSIX.
The portability of WebAssembly.

WASIX extends WASI with the features real applications need. Bring your C, C++, Rust, and Python applications to WebAssembly—with the tools you already know.

01 / MORE OF WHAT YOUR CODE NEEDS

WebAssembly.
With the missing pieces.

Keep the portability. Add the system capabilities.
WASIX builds on the WASI ABI to bring more existing software to Wasm.

Real networking

Connect to the world with TCP and UDP sockets, IPv4, IPv6, and DNS resolution.

socket · bind · connect

Threads that work together

Bring parallel workloads to Wasm with native threading primitives and synchronization.

pthreads · thread_spawn · futex

The whole process

Fork processes, launch programs, and wait for results. Keep your application’s workflow intact.

fork · exec · wait

A familiar filesystem

Read, write, and navigate files with POSIX-style operations, directories, and pipes.

open · read · write · chdir

Built for async

Poll sockets and files without blocking. Build event-driven applications with runtimes like Tokio.

poll · events · async I/O

Keep your tools feeling native

Support interactive terminals, signals, and familiar C control flow with setjmp and longjmp.

TTY · signals · setjmp / longjmp

Capabilities depend on the runtime and toolchain configuration.Explore the WASIX extensions

02 / REAL SOFTWARE, ALREADY BUILDING

A whole ecosystem.
Within reach.

From command-line essentials to language runtimes. Explore the packages and toolchains being built for WASIX with wasinix, our Nix-based package collection.

Read the getting started guide

Install wasixcc

$curl -fsSL https://wasix.cc | sh

For macOS and Linux. Installs the compiler, LLVM, and WASIX sysroot.

Compile something great

# Compile your C program to WebAssembly

wasixcc hello.c -o hello.wasm

Run it with Wasmer

wasmer run hello.wasm

Install Wasmer, then run this command. Run the WebAssembly module you just compiled.

Full C / C++ setup instructions

Run your .wasm with Wasmer

Built in the open. Built to go further.
