Ory powers logins for some of the world’s most visited websites

In April 2025, OpenAI.com and ChatGPT.com are ranked amongst the most visited websites globally, with ChatGPT surpassing popular platforms like Twitter, Reddit, and Amazon by securing the 5th spot. OpenAI also ranks highly, placed 44th by Similarweb and 28th by Semrush, while Fandom.com is noted as the 37th most visited site according to Similarweb. These sites, each attracting millions of users consistently, face significant challenges in managing authentication and authorization due to their immense user base, which traditional IAM solutions struggle to handle. As a result, OpenAI/ChatGPT, Fandom, and Axel Springer have become customers of Ory, a company specializing in scalable and customizable IAM solutions, to address issues of user delays and disruptions during peak traffic times and to support their ambitious growth plans.
