ChatGPT Website Builder: How ChatGPT Sites Works (2026)

When people say “ChatGPT website builder” in late 2026, they usually mean ChatGPT Sites. It’s OpenAI’s built-in tool for describing a website or lightweight app in plain language, letting ChatGPT (via Codex) build it, and deploying it to a live link. It’s in public beta for Plus, Pro and workspace accounts (not Free or Go), and it’s private by default. Below is what it does, what it doesn’t, and when you’re better off taking ChatGPT’s code to a regular web host.

A quick note on sourcing: everything here comes from OpenAI’s own help center and developer docs as of November 2026. Sites is a beta product, so plans, limits and pricing are moving targets. Check the official help article before you rely on any specific number.

What ChatGPT Sites actually is

OpenAI describes Sites as a way to create and share a live website or lightweight app from Codex. You describe what you need, refine it with ChatGPT, then deploy a site that others can open. According to OpenAI, the feature includes:

• Hosting: the site runs on OpenAI’s infrastructure, so you don’t need a separate host.
• Access controls: you decide who can open it.
• Storage and a database: per the help center, each Site’s database can hold up to 10 GB, and file storage has no fixed per-Site cap (overall usage limits still apply).

OpenAI positions it for focused websites and lightweight apps. Think an event page, an internal tool, a small calculator, or a team dashboard rather than a full e-commerce store. The help center also notes that some frameworks, private networks, databases, background services and hosting patterns aren’t supported.

Who can use it

Building or editing a Site counts toward your Codex usage. Running and hosting it, including traffic and storage, is metered separately. OpenAI’s own pages don’t fully agree on pricing: the Codex developer docs describe a monthly allowance that covers initial hosting usage, while the help center says hosting is currently included for Plus and Pro. Treat any “free hosting” as a beta-period arrangement that could change.

How to build a website with ChatGPT Sites

The help center describes this workflow on the web and in the desktop app. Menu names may differ slightly depending on your plan and rollout.

1. Open the right workspace. Go to the Work area on the web, or Codex in the ChatGPT desktop app.
2. Describe the site. Be specific about pages, sections, tone, and any interactive pieces such as forms, filters, or a sign-up list. Attach any content or files you want included.
3. Review the preview. ChatGPT generates a preview. Ask for changes in plain language (“make the header sticky,” “add a FAQ section”) until you’re happy.
4. Save a version before deploying. OpenAI points out that each deployment URL is production. Save a version, check it, and only then deploy so you don’t break the live site mid-edit.
5. Deploy. Deploying generates the Site’s URL. At this point it’s still private: only you and your workspace admins can open it.
6. Set access. Use the Share option under Sites to choose who can visit. Business and Enterprise customers can publish publicly to anyone with the link. Enterprise admins have to switch public publishing on first.
7. Optional: connect a custom domain. Where available, you can point a domain you already own at the Site by editing its DNS records. Sites doesn’t register domains for you.

Privacy and data: what to check first

As a privacy-focused site, we’d look at this before building anything. Per OpenAI’s help center:

• For Business, Enterprise and Edu customers, OpenAI does not use these conversations or the Site information in them to train its models by default.
• For Free, Go, Plus and Pro users, OpenAI may use your ChatGPT conversations for training if the “Improve the model for everyone” setting is on. If you’re building something with client data or internal details on a personal plan, turn that setting off first, or don’t put sensitive material in the prompt at all.

Also keep in mind that a Site with a database is a place where visitor data can end up. If you collect names or emails through a form, you’re responsible for handling that data properly, just as you would on any other host. Third-party write-ups also say OpenAI’s terms bar Sites from handling payments or card data. We couldn’t confirm that wording in OpenAI’s own terms, so check the current terms yourself if you’re planning anything transactional.

The other “ChatGPT website builder”: code blocks and your own host

Before Sites, the usual approach was to ask ChatGPT for HTML, CSS and JavaScript and preview it in canvas. That has changed. OpenAI’s model release notes say that with the May 28, 2026 update, canvas is no longer available in GPT-5.5 Instant or GPT-5.5 Thinking. Writing and coding now happen in writing blocks and code blocks inside the chat, and paid users can reach canvas only through legacy models until those are retired. Not everyone is happy about it; there’s an active community request to bring canvas back.

You can still build a static page this way:

1. Ask ChatGPT for a single-file HTML page (or a small set of files) describing exactly what you want.
2. In the code block, switch from Code to Preview if the option appears. OpenAI’s code blocks help article says supported previews may include HTML pages, and that available actions vary by plan, device, model and rollout.
3. Copy the code into files on your computer and upload them to any web host or static hosting service you choose.

This route works on any ChatGPT plan, and you keep the files. The trade-off is that you handle hosting, HTTPS, updates and security yourself.

Sites vs. code you host yourself

Our take

ChatGPT Sites is the fastest official way to go from an idea to a working, shareable page, especially for internal tools on a Business plan where data isn’t used for training by default. For a public-facing website you plan to keep for years, we’d be cautious. It’s a beta, pricing isn’t settled, and we couldn’t find a documented way to export a Site’s code in OpenAI’s docs as of November 2026. For anything long-lived, using ChatGPT to write the code and hosting it yourself keeps you in control. Revisit Sites once it leaves beta and OpenAI publishes firm pricing and export options.
