ChatGPT Sites is a feature for creating, previewing, publishing and sharing interactive websites and lightweight apps inside a ChatGPT conversation — dashboards, resource pages or customer portals, for example. It launched as a public beta on 9 July 2026. It is only open to Plus, Pro, and Business and Enterprise workspaces; Free and Go cannot use it, so check your account tier before starting, to avoid discovering halfway through that the entry point doesn't exist.
Generate in Conversation, Deploy in Three Steps
On the web, pick the Work entry point; in the desktop app, pick ChatGPT then Work, or work in Codex. In the chat box, describe the website you want to build — the prompt needs to include the word website, or mention Sites. Give your content, files, data and constraints all at once: the more specific the description, the fewer rounds of fixes you'll need. Check the preview, and if something is off, keep asking in conversation for changes until you're happy. Step one: click Save to save a version. Step two: click Deploy to publish and get a production address. Step three: in Share, choose the audience and save. A new site is visible only to you by default. Every deployment address is a production address, and changes update the live version directly; restoring an old version restores only the code, not the database or uploaded files, so save a version before making big changes.
Domains, Plugin Backends and Storage Limits
The first deployment gives you a default address; personal accounts use a random identifier by default rather than the username. If you already own a domain, you can connect it — you'll need to change the DNS records yourself, as Sites doesn't register domains for you. A Site can also host an MCP server, providing tools to ChatGPT through a plugin so the conversation can use that Site's workflow directly. To do that, have ChatGPT or Codex add an MCP server to a new or existing Site, and state what information the tools may read and whether they may change anything. Each Site's database holds at most 10 GB; file storage has no fixed per-site cap, but usage and storage limits still apply.
Know Three Limits Before You Build
First, some frameworks, private networks, databases, backend services and hosting modes may not be supported — only web forms the Sites runtime can host — so don't expect it to cover a complex backend end to end. Second, building and changing a site consumes Codex usage, while running and hosting usage is counted separately; exact allowances follow the prompts shown in the product. Third, Enterprise workspaces have public publishing turned off by default, and an admin needs to enable it. Hosting is currently included in Plus and Pro subscriptions at no extra charge; according to OpenAI documentation, from 1 January 2027, usage beyond each plan's monthly allowance starts being billed. Protected health information and payment card data must not be handled, and content must not target children under 13 — don't cross those red lines.
