WebAssembly (Wasm) has been in production for years, used in popular applications like Microsoft Office.com, Figma, and streaming services such as BBC and Amazon Prime. Despite its proven stability and deployment, doubts persist regarding its readiness due to misconceptions about language support, WASI standardization, and threading capabilities. However, numerous server-side and serverless applications, including platforms like Fermyon Cloud, Fastly Compute@Edge, and Cloudflare Workers, demonstrate the widespread use and reliability of Wasm in production environments. The real-world adoption of WebAssembly proves its production-readiness.
