In 2026, AI didn't replace the web. It became part of it. Your browser now ships a built-in MCP server. Chrome DevTools debug your app with AI. Native Web APIs let you summarize, translate, and prompt right from your frontend code. Meanwhile, the web feeds agents right back through standards like LLMs.txt and MCP tools that make sure models always have the right documentation. AI builds the web. The web feeds AI. And now, AI lives inside the browser itself. In this talk, we'll follow a feature from idea to production and demo this new symbiosis in action: coding agents, AI-powered debugging in Chrome devtools, Web AI APIs, WebMCP, and more. Because your next website won't just be built with AI. It will be built for humans and AI agents alike. AI isn't just for Python folks. The web is AI's new home.

A conference session by developer advocates from Microsoft and AWS covering how AI is transforming web development across the full lifecycle. Topics include using AI coding agents with 'skills' (lightweight plugins) for automated workflows, leveraging the Chrome DevTools MCP server for AI-driven debugging and performance analysis, using experimental browser-native AI APIs (Summarizer, Proofreader, Prompt API with Gemini running locally) to add AI features without cloud calls, implementing LLM.txt for agent discoverability, and the emerging Web MCP proposal that lets web apps expose tools directly to agentic browsers — analogous to how responsive design adapted sites for mobile.
