Sandcastle: data/AI apps for everyone

Airbnb developed a platform called Sandcastle to help data scientists and ML practitioners bring their data- and AI-powered product ideas to life in an interactive way. Sandcastle integrates with Onebrain, a packaging framework for data science and prototyping code, and kube-gen, a code-generation layer on top of Kubernetes. This platform allows developers to create and share interactive web applications within 10-15 minutes of checking in their code. Over 175 live prototypes were developed in the last year, with 6 of them being used for high-impact use cases. These prototypes were visited by over 3.5k unique internal visitors across over 69k distinct active days.
