OpenAI Adds "Sites" to Codex, Letting You Share Apps via URL

On June 2, 2026, OpenAI announced on its official X that it had added a new feature called "Sites" to its coding agent "Codex," which converts work, ideas, and plans into interactive websites and apps that can be shared via a single URL. It is initially rolling out as a preview to ChatGPT's Business and Enterprise plans, with plans to expand to broader availability in the future.

Sites is a feature in which, simply by giving instructions via a prompt, Codex generates apps such as internal tools, dashboards, project boards, and review screens, handles hosting end-to-end, and issues a shareable URL. The flow involves adding the @Sites plugin within Codex, instructing it to create and deploy a site, saving a version for review or deploying to production, and sharing via URL. It also supports deployment from existing projects (official documentation).

On the technical side, it adopts Cloudflare Workers-compatible ES module output, and supports the relational database D1 and object storage R2. Workspace authentication, custom access control (owner/admins, entire workspace, specific users/groups), and environment variable/secret management are also possible. In terms of availability, it is enabled by default in Business, while in Enterprise an administrator enables it via RBAC (role-based access control) settings.

Codex originally evolved as a coding assistance tool offered as an IDE extension, CLI, and cloud version, and in recent years has been strengthened with integration into the ChatGPT app, browser control, parallel task processing, and more. Sites pushes this toward "no-code/low-code style app building, instant hosting, and sharing," with a strong focus on business use. The announcement is part of business-oriented updates related to "Intelligence at Work," released alongside an Annotations feature that lets you specify part of a created artifact and instruct revisions, as well as six business plugins for data analysis, creative, sales, product design, investment, and more (9to5Mac).
