In this talk, I'll dive into how sandbox.bio was built, with a focus on how WebAssembly enabled bringing command-line tools to the web. Although these command-line tools were originally written in C/C++, they all run directly in the browser, thanks to WebAssembly! Since the computations run on each user's computer, this makes the application highly scalable and cost-effective. Along the way, I'll discuss how to get started with WebAssembly, along with its benefits and pitfalls (it's a great technology but not always the right tool for the job!).
