Context

Gadgets, a personal-app system presented by Cloudflare, moves sharing permissions into the hosting platform. Each gadget contains one shareable item, such as a slide deck, together with its application code. In the talk, this lets an add features for that particular deck while the platform controls who can access it.

The described design confines the generated interface to a browser and its server code to a separate restricted environment. Their permitted connection lets the app function while restricting access to the outside world. That is a concrete containment strategy for personalized software. The talk describes the architecture, rather than establishing the title's broad promise that generated apps are safe.
