OpenAI Opens ChatGPT Sites in Preview for Business Workspaces

TLDR

On June 2, 2026, 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 first Business ship.

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

Distinct from the July 9 public-beta story (openai-chatgpt-sites-public-beta): June 2 is Business preview / internal hosting; July 9 is consumer-tier rollout + public publish.

Why this story matters

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.
