ChatGPT Sites Business Preview: Hosted Internal Apps With Default Enterprise Plumbing
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.
