WebAssembly: Yes, but for What? – ACM Queue
July 17, 2025
WebAssembly (Wasm) turns 10 this year, which, in software terms, just about brings it to the age of majority. It has been polished, prepared, explored, and deployed, but in the language of American speculative fiction author William Gibson, we are now as ever in the unevenly distributed future: WebAssembly has found a niche but not yet filled its habitable space. This article attempts to inventory the early Wasm wins and losses and identify winning (and losing!) patterns, and then goes further to extract commonalities between these patterns: What is it that makes for a successful Wasm deployment? These observations are then used to predict the future, suggesting new areas where Wasm will find purchase in the next two to three years.
Web Assembly is a decade old now–yet while it has long been widely supported, its adoption has lagged what might be expected of such an enabling technology.
Here Andy Wingo looks where it has been successfully adopted, and where we might see if coming in the future.
