OpenAI announced that approximately three months after the launch of ChatGPT Sites, users have created over 5 million sites. The platform has introduced collaborative editing, targeted private sharing, reduced deployment time by about half, the ability to check site databases through conversations, and the option to bind custom domain names.

This feature initially entered commercial and enterprise workspaces in preview form on June 2, 2026, allowing Codex to turn prompts into hostable lightweight websites or applications, hosted on Cloudflare, with ChatGPT login and file storage. On July 9, it expanded to paid tiers and allowed public publishing. Starting August 20, site owners can add members within the same workspace as editors, allowing them to modify, save, and push new versions to the same URL after the owner's initial publication; ownership, keys, domain names, and audience settings remain with the owner. Private sharing allows external visitors to be invited via email, requiring them to log in with the invited account without needing to join the workspace or make the site public. Custom domain names were not available at the launch of enterprise workspaces.

Official examples include dashboards, portfolios, onboarding pages, Q&A games, local maps, and itineraries. Demonstration sites feature pixel exploration games, 3D coloring in browsers, summaries of earthquakes and space weather, sound-enabled drama calculators, and Japanese word chain games. Documentation states that Sites is in public testing, targeting Plus, Pro, Business, Enterprise, and Edu users. Codex has previously reported over 5 million weekly active users, of which about 20% are non-coding knowledge workers, growing faster than traditional engineers.

Buyers are teams and individual creators looking to write fewer deployment scripts; sellers are OpenAI, which bundles generation, hosting, and permissions into a single subscription. The driving force is the permission gap following the 5 million sites, not a new model. Funding comes from paid seats covering hosting and agent usage. Beneficiaries are teams that can deliver internal tools using their own domain names; those under pressure include low-code platforms that charge hosting fees per project and traditional website building processes that still require moving applications out of conversations to go live.
