We’re happy to announce the 1.0 release of Jco: a native Javascript WebAssembly toolchain and runtime built for WebAssembly Components and WASI 0.2 1. Jco can natively run Wasm Components inside of Node.js, making it easy to take libraries written in different programming languages and execute them using the Node.js runtime. And by implementing the entirety of the WASI 0.2 API surface, those compo

Until now, one piece missing from WebAssembly standalone engines was the ability to spawn threads. Browsers have had this ability for some time via Web Workers, but standalone engines had no standard way to do this. This post describes the work of several collaborators to bring about wasi-threads, a proposal to add threads to WASI. It will explain the history to this proposal, the work done to get

As of today, the Wasmtime WebAssembly runtime is now at 1.0! This means that all of us in the Bytecode Alliance agree that it is fully ready to use in production. In truth, we could have called Wasmtime production-ready more than a year ago. But we didn’t want to release just any WebAssembly engine. We wanted to have a super fast and super safe WebAssembly engine. We wanted to feel really confiden

Our founding members are Mozilla, Fastly, Intel, and Red Hat, and we’re looking forward to welcoming many more. We have a vision of a WebAssembly ecosystem that is secure by default,
