Build and publish web apps directly in ChatGPT
Summary
OpenAI's Sites plugin eliminates traditional web development bottlenecks—creators can now build, deploy, and iterate on fully functional web apps directly in ChatGPT with zero infrastructure setup. The tool includes built-in hosting, storage, and integrates with plugins like Build Web Apps to handle design, implementation, and testing automatically.
Key Takeaways
- Sites plugin provides built-in hosting and storage, eliminating the need to configure separate backend services—apps publish immediately without DevOps overhead.
- Natural language iteration loop accelerates development: users describe changes in plain English while ChatGPT handles implementation, reducing feedback-to-deployment cycles from hours to minutes.
- In-app annotation tools enable precise feedback—developers can drop targeted comments directly in the browser preview to specify exact updates needed.
- Plugin ecosystem (Build Web Apps) extends capabilities across design, implementation, and testing—users can chain multiple AI tools for polished, production-ready applications.
- Idea-to-deployment timeline compressed dramatically—demonstrated building a functional 2D side-scrolling game with pixel art from concept to working product entirely within chat.

Let me show you how to build and deploy web apps directly from ChatGPT. I'm going to use Sites, a new plugin that lets you create fully functional web apps in minutes. It includes built-in hosting and storage so you can publish your app immediately. No need to set up a separate service. You can start directly in the chat window to begin. I'll start by describing what I want. Build a launch site for a design conference with speaker cards, a filterable agenda, and a clean minimalist editorial style. Behind the scenes, it sets up the project, writes the code, and keeps working until the first version is ready. I can open up the result and try it for myself. This is a strong start, but I want the schedule layout to be easier to scan and the keynote to feel like the main event. So I'll ask to r…
