Beyond the Chatbot: Gen UI & the Execution Trust Problem - Harshil Agrawal - Cloudflare - dotJS 2026

Why watch

Harshil Agrawal demonstrates how Generative UI replaces traditional chatbots by having LLMs return React components instead of text. The core challenge is execution trust—running AI-generated code safely in production. This talk showcases V8 isolates at the edge as a solution that provides both performance and security isolation, enabling milliseconds-level TypeScript execution while containing the blast radius. Ideal for developers building AI-powered applications who need to render dynamic, user-tailored interfaces.
