A cross-platform WebAssembly runtime with WASIX, WASI 0.2 default, jco support, and a public package registry.
Wasmer is a high-performance, cross-platform WebAssembly runtime that supports multiple compilation backends including LLVM, Cranelift, and Singlepass. The 7.1.0 release (March 2026) ships WASI 0.2 as the default preview, and integrated jco support for running components in JavaScript hosts. It introduced WASIX, a superset of WASI that adds POSIX threads, sockets, and process management — enabling unmodified CLI tools like curl and git to run as Wasm binaries. The Wasmer Registry at wasmer.io hosts thousands of published Wasm packages and provides a universal package manager for the ecosystem.
