From a technical perspective, Clay was definitely a creative solution. In order to support legacy versions of the mobile app, and get around limited local file access, Clay bundled the entire page at run time into a Data URI. Whilst unconventional, this technique did have the advantage of being super fast and completely offline. It also meant that app developers didn’t have to worry about mismatched versions of their configuration pages and watch apps. Clay featured 100% test coverage that was enforced during CI.
