TL;DR Developers can now build and host ChatGPT apps with Gadget. Each app comes with full integration to OpenAI’s ChatGPT Apps SDK, built-in OAuth 2.1 authentication, a hosted MCP server, and fully set up React UIs that render natively inside ChatGPT.

We’re excited to announce official support for building embedded ChatGPT apps. Starting today, developers can build, host, and scale ChatGPT apps directly within Gadget, using our new ChatGPT connection.

The connection provides everything you need to build and run ChatGPT apps, allowing developers and agencies to skip the setup and focus on what makes their applications unique. Every project boots up with a Postgres database, Node.js backend, and React frontend, hosted on Google Cloud and seamlessly integrated from the start.

Like other connections in Gadget, the new ChatGPT plugin manages the entire ChatGPT Apps SDK implementation, from user authentication and embedded React frontend setup to the MCP (Model Context Protocol) server and tool integrations that power the experience. It removes the need for setup and boilerplate, letting you focus on bringing your idea to market faster in this incredible, burgeoning ecosystem.

Getting started is easy! Create a new Gadget app and follow the in-editor instructions to connect to ChatGPT in seconds.

Endless new opportunities for the creative and ambitious

OpenAI’s ChatGPT Apps SDK lets developers create web applications that live inside ChatGPT, which means you can build apps for 800M+ active monthly users. Instead of sending ChatGPT users to a separate website or dashboard, apps now exist where conversations happen, combining chat, app functionality, and custom UI into one seamless experience.

It’s a major shift in how developers can reach users, but building one from scratch isn’t easy. Under the hood, each ChatGPT app is, at minimum, an MCP server, an OAuth 2.1 provider, and an embedded (and bundled) frontend. And that’s assuming your app doesn’t need other basics like a database, backend infrastructure, and developer tooling.

There’s a lot of setup and boilerplate work involved before you can begin writing the code that makes your application unique. That’s exactly the problem Gadget sets out to solve.
