A site with an address like xxx.chatgpt.site is one that a ChatGPT user built and published with a feature called ChatGPT Sites. OpenAI provides the place where the site lives (the hosting), but OpenAI does not create the content of these sites, nor does it review or approve them. ChatGPT Sites is also still in beta, and there is no guarantee that a site will stay online forever. For this article, I checked OpenAI's help articles, developer guide, terms, and release notes in the original on October 11, 2026, and summarized what chatgpt.site actually is, what it costs, how far you can rely on it in production, and how custom domains work.

Is chatgpt.site an official OpenAI site?

No, users build these sites

OpenAI only provides the hosting. Whoever built the site is responsible for its content.

What does it cost?

No extra charge during the beta

It is included in plans such as Plus and Pro, up to a limit. Pricing after the beta has not been announced.

Will my site stay up forever?

There's no guarantee

The beta is provided "as is," and OpenAI can take sites down at any time.

Can I use it in production?

Prototypes and internal use are the safe bet

Some uses are prohibited, and the creator carries the responsibility. Avoid it for sites you can't afford to have go down.

Sources: OpenAI Help Center, "Creating and using ChatGPT Sites," and "ChatGPT Sites Terms" (updated July 23, 2026). Checked on October 11, 2026. The answer to "Can I use it in production?" is my own judgment based on the terms and constraints.

Contents

1. What is chatgpt.site? Who builds these sites

ChatGPT Sites is a feature that, when you ask ChatGPT to "make a website like this," not only builds the site but also publishes it for you. Each published site gets a subdomain of a domain that OpenAI owns. The terms state that OpenAI may provide OpenAI-owned subdomains, such as ones ending in chatgpt.site, and the developer guide gives goblin-tales.openai.chatgpt.site as an example of the format.

In other words, if you come across a site ending in chatgpt.site, it is a site that some ChatGPT user built. Here are the roles of the three parties as the terms define them.

  • Creator (a ChatGPT user)

    Builds the site's content and decides who can see it.
    • Is solely responsible for the content (2.2).
    • Becomes the controller of any personal data collected (3.2).

  • OpenAI

    Provides the hosting and the subdomain.
    • Does not review, endorse, or approve sites (2.2).
    • Can take a site down, for example for violating the terms (5.2).

  • Visitor

    Opens and uses xxx.chatgpt.site.
    • Should know it is not an official OpenAI site.
    • Can report a site that looks suspicious.

The terms also prohibit presenting a site in a way that suggests OpenAI made it, endorses it, or is affiliated with it (4.3), and they prohibit hoarding subdomains, acquiring an unreasonable number of them, or reselling them (2.7).

Don't assume a site is official just because it's on chatgpt.site. Be especially careful with pages that ask you to sign in or pay. According to the help article, if you believe a site violates the terms, you can report it through OpenAI's content reporting form, including the site's full URL. OpenAI may remove or restrict sites that may violate its policies.

2. What ChatGPT Sites can do

You build a site in Work on ChatGPT for the web, or in Work or Codex in the desktop app. Including the word "website" in your request, or typing @Sites, starts the site-building flow. ChatGPT creates a preview, you tell it what to change until you're happy with it, and then you publish. OpenAI's examples include dashboards, project trackers, launch calendars, prototypes, internal portals, and reports. Work itself, the feature for handing tasks off to ChatGPT, is covered in "What Is ChatGPT Work?"

Storing data

A database for table-shaped data (D1, up to 10 GB per site) and storage for files such as images and documents (R2, no stated limit).

Sign-in

Public sites can add "Sign in with ChatGPT." The site receives the visitor's email address and, if available, their name.

Traffic stats

Visitor and page view counts are tracked automatically (except for sites in Enterprise workspaces).

Internal tools

On Business and Enterprise, a site can show read-only information from the apps each visitor has connected, such as an issue tracker.

Co-editing and schedules

You can let people in the same workspace edit a site, or schedule a published site to be updated regularly.

What it can't do

Raw TCP connections, some frameworks, private corporate networks, always-on background processes, and more. HTTP, HTTPS, and WebSocket are supported.

You can also prepare a local project with Codex and then publish it. In that case, each saved version records which Git commit it was built from.

3. Who can use it, and where

According to the help article, ChatGPT Sites is available as a public beta on the plans below. The release notes introduced it as a public beta on July 9, 2026, rolling out first to Pro, Pro Lite, and Edu, with Plus following a few days later.

Can use ✓ Plus ✓ Pro ✓ Business ✓ Edu △ Enterprise (enabled by an admin)
Can't use Free Go

In company workspaces, who can use it depends on the admin's settings. It is on by default for Business, while on Enterprise an admin has to turn it on, and publishing to the open internet is off by default. Also, as of July 9, public sharing and the expanded beta were not available in the European Economic Area (EEA), Switzerland, or the UK. I found no announcement in the release notes that they have since launched in those regions. For the differences between plans, see also "Comparing ChatGPT's Pro plans."

4. Pricing and usage limits

ChatGPT Sites has no separate price. The help article says that during the beta, Sites usage is included up to the limits of each plan. Broken down into now, when you hit a limit, and after the beta, it looks like this.

Now (beta)

Included in your plan

You can use it within a Plus, Pro, Business, or similar subscription. OpenAI's documentation mentions no additional charge for Sites.

When you hit a limit

Some things stop

You may be unable to create new sites, add more storage, or keep high-traffic sites public. You can still edit and manage existing sites.

After the beta

Pricing not announced

Some users report seeing a notice to the effect that upgrade or add-on purchase options will be offered after the beta, but I have not verified this.

The actual limit values have not been published. Your current limits are shown in the Sites interface, and ChatGPT lets you know when you're getting close. Limits are counted across all the sites you own, and they may change during the beta. If you use your own domain, you pay for that domain separately (section 7).

5. Will a site stay up forever? What "beta" means

By design, the sites you build are not temporary. The developer guide describes a site as "persistent hosted output" and explains that it stays in your list of sites even after the conversation that built it has ended. Even so, there is no guarantee that a site will stay online forever, for three reasons.

  • Betas come with no guarantees OpenAI's Service Terms provide beta services "as is" and do not guarantee that they will be available, uninterrupted, or that content will not be lost (Section 2).
  • OpenAI can stop a site at any time The Sites terms state that OpenAI may remove or unpublish a site at any time for any reason, including when it violates the terms or may cause harm (5.2).
  • Usage limits Once you hit a limit, you may no longer be able to keep high-traffic sites public (section 4).

🔎 What I checked (October 11, 2026)

When I opened goblin-tales.openai.chatgpt.site, the example given in the developer guide, I got a 404 No site here page. Even an official example doesn't necessarily stay up.

There has been no announcement so far that Sites itself will be discontinued. However, the official documents I reviewed did not say what happens to published sites if you cancel your plan or downgrade to Free. If you're hosting an important site, you'll want to confirm this beforehand.

6. Can you use it for a production site?

OpenAI does not say "don't use it in production." In fact, the developer guide states, "Every Sites deployment URL is a production deployment," and recommends saving a version and checking it first if you want to review before publishing. That said, there are constraints you should know about before putting a site into production.

Uptime guaranteesIt's a beta, so there's no guarantee, and no service level agreement (SLA) is mentioned.
Data locationYou can't choose the country or region where your site, code, data, and logs are stored (as of launch).
Prohibited usesProcessing health information (protected under HIPAA in the US) or payment card data, sites aimed at children under 13, malware, phishing, and impersonation. Payments are allowed only through an external payment processor.
Creator responsibilityIf you collect visitors' personal data, you become its controller. Where required, you need to post a privacy policy and get cookie consent (terms 3.2).
OpenAI attributionOpenAI may show a credit indicating the site was made with ChatGPT, for example at the bottom of the site (terms 1.3).

Given these conditions, here is how I think it makes sense to decide when to use it (this is my own judgment, not an official recommendation).

✓ Good fit

  • Prototypes and demos
  • Internal dashboards and trackers
  • Pages with a fixed lifespan, such as event information
  • Small personal pages

✗ Better to avoid

  • A company's main site, where downtime halts sales or operations
  • Sites that handle payments or a lot of personal data
  • Records you want to keep for years

If you're using it for something close to production, attaching your own domain means you won't have to change the URL if you later move to another host. And if you build from a local project, you keep the source code on your side as well.

7. Custom domains and changing the URL

You can use a custom domain where the feature is available. Sites does not register a domain for you, so you need a domain you already own and whose DNS settings you can change. Custom domains were not available in Enterprise workspaces at launch.

  1. Open the site's settings Select "Add domain."
  2. Enter the domain you want to use It can be a root domain (example.com) or a subdomain (such as www.example.com).
  3. Add the DNS records Add the DNS records and values that Sites shows you in the control panel of the company you bought the domain from.
  4. Check the status Wait a few minutes, then refresh the domain status in the site's settings.

The owner can also rename the chatgpt.site address. When you do, the old address redirects to the new one, and you don't need to rebuild the site. The naming rules are as follows.

✓ Allowed: at least 5 characters, starting with a lowercase letter, using lowercase letters, numbers, and hyphens (e.g. team-board2)
✗ Not allowed: ending with a hyphen, or consecutive hyphens (e.g. team--board, board-)

8. Choosing who can see a site, and deleting it

A newly created site is at first visible only to you and your workspace admins. From there, you widen access step by step down the list, only as far as you need (which options are available depends on your plan and settings).

  1. Only you and admins DefaultOnly you and your workspace admins can see the site.
  2. Selected peopleSpecific people or groups in your workspace. You can also show it to outsiders by inviting their email addresses (view only, no editing).
  3. Everyone in the workspaceAll members of the same workspace can see the site.
  4. Anyone on the internetAvailable only when public sharing is allowed. Anyone can view the site without signing in, and it may appear in search engines.

If you just want to stop publishing a site, change sharing back to yourself or a limited set of people. To delete it completely, select "Delete site" from your list of sites, type the site's name (its slug), and click "Permanently delete." A deleted site cannot be restored. Incidentally, one public site I looked at was configured to allow search engine crawlers everywhere.

9. Personal data and model training

The rights to the text, images, code, and other content you put on a site remain with you, the creator. On that basis, OpenAI receives permission to use that content to the extent needed to run the site at the visibility level you chose (terms 1.1 and 1.2). If you make a site public, you also give OpenAI permission to use the site's name and logo, solely for the purpose of showcasing the site (terms 4.1).

Whether your conversations with ChatGPT while building or editing a site are used for training depends on your plan.

Personal plans such as Plus and Pro

If the "Improve the model for everyone" setting is on, they may be used for training.

Business, Enterprise, and Edu

Not used for training by default.

Where to find the setting is explained in "Are ChatGPT and Codex conversations used for training?"

Summary

xxx.chatgpt.site is a site that a ChatGPT user built with ChatGPT Sites and that is published on OpenAI's servers. OpenAI only provides the hosting. It does not review or approve the content, and responsibility lies with the creator.

During the beta, the cost is included, up to a limit, in the price of paid plans such as Plus and Pro, and pricing after the beta has not been announced. The beta comes with no guarantees, and OpenAI can take sites down at any time. It's handy for prototypes and internal tools, but it's not suited to production sites that you can't afford to have go down. If you do use it, the safe approach is to attach your own domain, keep the source on your side, and limit visibility to only what you need.

Sources

I checked all official specifications and terms in the original on October 11, 2026. I did not build or publish a site for this article. The checks of the example site and the public site are what I saw when opening them from the outside on the same day. Because the feature is in beta, availability, limits, and features may change.
