Why this matters
ChatGPT apps are a new kind of web app: they live directly inside ChatGPT, reaching 800M+ monthly users. No tabs, no redirects, no context switching. This is a huge opportunity for B2C and B2B app developers.
But building one from scratch isn’t simple. Aside from the core functionality of your app, you need to build an MCP server, OAuth for user authentication, and set up frontend embedding in accordance with ChatGPT's API guidelines. This is a lot of setup and boilerplate work.
Luckily, Gadget’s new template takes care of all of that for you.
How does it work?
Connecting your Gadget app to ChatGPT literally takes 10 seconds:
- You copy/paste your App URL directly into ChatGPT
- You authenticate yourself as a user using the email/password or Google SSO authentication options that the template has built in
- You’re fully set up and ready to customize your app

The ChatGPT ecosystem is still young, but the opportunity is enormous. Gadget gives developers a way to explore it without friction. Build faster, ship faster, and reach users where they already are.
