Codex Sites: Build and Deploy Hosted Websites Directly from Codex
CodexOpenAI launched Codex Sites in preview on June 2, 2026, a new plugin that enables teams to create, save, deploy, and share interactive websites, dashboards, internal tools, web apps, and games hosted directly by OpenAI. Users describe what they want, Codex builds and validates the project, then deploys it to a shareable URL with optional workspace authentication via Sign in with ChatGPT. Sites is available by default for ChatGPT Business workspaces, with Enterprise admins able to enable it via role-based access controls. The announcement was part of OpenAI's Intelligence at Work event, as the platform now serves over 5 million weekly active users.

What Is Codex Sites?
On June 2, 2026, OpenAI introduced Codex Sites, a new hosted deployment plugin available in preview inside the Codex app. Sites fundamentally changes the output of a Codex session: instead of producing local files that a developer must configure and host separately, Codex can now build an interactive web application and deploy it directly to an OpenAI-managed URL in the same workflow.
Teams can use Sites to create dashboards, internal planners, knowledge bases, project trackers, web apps, and even games. The resulting applications are shareable via URL within a workspace, with authentication handled through Sign in with ChatGPT so that only authorized team members can access them.
How It Works
The workflow follows a describe-build-deploy pattern. A user opens the Sites plugin from the Codex app sidebar, describes the application they want, and Codex builds it, validates the build, and saves a deployable version for review. Once approved, the user deploys to a live production URL. The Sites panel also manages hosted environment variables and secrets, keeping sensitive configuration out of the codebase.
Under the hood, Sites uses infrastructure compatible with Cloudflare Workers and supports applications with persistent storage: relational databases via D1, object storage via R2, and workspace-level authentication. OpenAI is partnering with Wix, Base44, Replit, Lovable, Figma, and Emergent to broaden the hosting ecosystem.
Availability and Access
Sites launched in preview and is currently scoped to ChatGPT Business and Enterprise workspaces, with broader rollout planned. For Business workspaces, Sites is enabled by default. Enterprise workspace administrators must enable it through role-based access controls before members can use it.
This launch is part of OpenAI's strategic pivot for Codex toward knowledge workers. As of the June 2 announcement, non-developers represent approximately 20% of Codex's 5 million weekly active users and are growing three times faster than the developer base.
