WebAssembly 2026: The year of backend Wasm?

WebAssembly (Wasm) is no longer just for the browser. In 2026, Wasm is rapidly becoming the default runtime for serverless functions and edge computing. Its lightweight nature and security sandbox make it ideal for multi-tenant cloud environments.

Startups like Fermyon and Cosmonic are leading the charge, enabling developers to write microservices in any language that compiles to Wasm and deploy them instantly.
