Make a website with ChatGPT

Updated November 9, 2026

Overview

Not open to everyone yet. Right now only the ArchFoundry team can make websites this way. This page says how it works once it opens.

Ask ChatGPT for a website, and ArchFoundry puts it live at its own address, an address like rosas-bakery.sites.archfoundry.ai. It can include a contact form that emails you.

When you first connect, ArchFoundry asks only for your email, or you can use Continue with Google. Your site goes live as soon as ChatGPT publishes it. If you used only your email, we then email you a link: open it within 7 days to confirm your email, or the site turns off. Messages from your site's form wait until you confirm. No email? Check spam, or write to support@archfoundry.ai.

Prerequisites

  • An email address or a Google account.
  • ChatGPT on the web, at chatgpt.com on a computer.

Developer mode is a beta on ChatGPT on the web for paid plans.

If you use ChatGPT through work or school (Business, Enterprise or Edu), an admin or owner may need to turn on developer mode or publish the app for you. Ask them.

Steps

  1. On a computer, open chatgpt.com, then Settings, then Apps. Some accounts show Apps & Connectors instead.
  2. Click Advanced settings and turn on Developer mode, which lets you add your own apps.
  3. Click Create app. Name it ArchFoundry, paste https://app.archfoundry.ai/mcp as its URL, choose OAuth for authentication (this is how you sign in) and click Create.
  4. A new window opens. Type your email or click Continue with Google, then click Allow.
  5. In a chat, click +, then More, and choose ArchFoundry. Then ask ChatGPT for a website.

Coming soon: ArchFoundry in ChatGPT's apps directory, so you can add it without the address. When it is listed:

  1. In Apps, search for "ArchFoundry".
  2. Open it and connect, then sign in as in step 4.

Until then, pasting the address is the way in.

Example

Ask ChatGPT for a small site with a contact form.

text
Make me a one-page website for Rosa's Bakery,
with our opening hours and a contact form.
Publish it with ArchFoundry.

Expected result: ChatGPT publishes the site and gives you its address, such as https://rosas-bakery.sites.archfoundry.ai. To use another name, put it in your request.

What ChatGPT can do

  • Check websites. Only reads your site. Says whether your site is on, its versions and how many visitors it had.
  • Read files. Only reads your site. Lists your site's files and reads them back.
  • Make a website. Makes a new website and its address. Visitors see nothing until you publish.
  • Add files. Adds or changes files, as changes not yet live. Visitors see nothing until you publish.
  • Publish. Changes what visitors see. Puts your changes that are not yet live at your address.
  • Make and publish a website. Changes what visitors see. Makes a small new website and puts it live in one go.
  • Put back a version. Changes what visitors see. Puts back an earlier version.
  • Take offline. Changes what visitors see. Turns your site off, and we delete its files 7 days later.
  • Ask for your own web address, like rosasbakery.com. Notes that you want your own web address. This is not available yet.

Cost

Websites are free for now. Nothing here takes a payment.

Verify it worked

  • Open the address ChatGPT gave you. Your site is there.
  • If you used only your email, check your email for the link that confirms your address, and open it within 7 days. The email names Claude for now. No email? Check spam, or write to support@archfoundry.ai.

Troubleshooting

An email or message from ArchFoundry says Claude. Our messages, emails and your site's page name Claude for now. Here, read it as ChatGPT.

Claude was not given permission for this. Connect ArchFoundry again in Claude and allow it. Remove ArchFoundry in ChatGPT, add it again with the steps above, and click Allow.

ArchFoundry websites are not open yet. Nothing was created. Websites are open only to the ArchFoundry team for now. Write to support@archfoundry.ai to hear when they open.
