> OpenAI opened ChatGPT Sites in preview for Business workspaces with Codex—create, iterate, deploy lightweight full-stack internal apps with hosted URLs, Sign in with ChatGPT, and admin RBAC. Category ship weeks before July’s public-beta splash.

**Correction (October 14, 2026):** Verified the July 9 expansion against its dated release-note entry, added its regional limits, and removed an unsupported comparison of preview and later service-level agreements.

Hosted “vibe coding” with **default enterprise plumbing** (workspace auth, admin kill-switch, OpenAI hosting) is a product category, not a demo. Dating the **Business preview** correctly matters for readers who saw Sites first on work accounts weeks before the July public splash.

OpenAI’s **ChatGPT Business release notes** shipped **ChatGPT Sites** in **preview** for **Business workspaces with Codex access**. Teams can ask Codex to **create, iterate, and deploy** lightweight full-stack **JavaScript/TypeScript** web apps for **internal** workspace use—with **hosted site URLs**, **Sign in with ChatGPT**, and data/file storage—while access stays **workspace-internal**. Business enables Sites **by default** (admins can disable); management under Workspace settings → Permissions & Roles / Sites. **July 9** later expanded Sites to **public beta** and **public URL** publishing—this article dates the **Business preview recorded in the June 2 notes**.

## What shipped June 2

| Item | Detail |
|------|--------|
| **Surface** | ChatGPT Sites (Codex plugin path) |
| **Audience** | ChatGPT **Business** workspaces with **Codex** |
| **Output** | Lightweight full-stack JS/TS apps; hosted URLs |
| **Access model** | **Internal** to workspace at preview |
| **Auth** | Sign in with ChatGPT |
| **Admin** | Default on for Business; RBAC + Sites settings |
| **Docs** | Codex Sites developer guide |

June 2 marks the **Business preview / internal hosting**; **July 9** marks the later **consumer-tier rollout + public publishing**. That expansion excluded the EEA, Switzerland, and the UK at launch; Plus followed over the coming days.

## Limits

- Business + Codex entitlement required—not Free/Plus alone at this ship.
- Internal workspace hosting only; public URLs are the July story.
- The June 2 release was a preview, not general availability.
