Read the Docs

Registered in June 2014, readthedocs.io serves as a permanent alias and redirect domain for the popular Read the Docs documentation hosting platform, which operates from its primary domain at readthedocs.com. The Read the Docs platform is one of the most widely used services globally for open source and commercial software projects to host, build, and publish technical documentation automatically from connected code repositories like GitHub and GitLab. Holding a global traffic rank of 950, readthedocs.io benefits from the massive, established audience of the Read the Docs platform, which serves millions of developers and technical users across the world every month. The domain has been continuously active for 11 years, with an expiration date set for 2028, indicating a long-term, committed ownership from the platform’s parent company. It uses Cloudflare for DNS infrastructure, with Google Workspace handling business email services for the domain, demonstrating professional, enterprise-grade domain management. As an official alias, it does not host any independent content of its own, instead directing all incoming visitors to the primary readthedocs.com domain. The .io top-level domain is widely associated with technology and open source developer projects, so maintaining this alias allows the platform to capture additional organic traffic from users who intuitively use the .io TLD when searching for developer-focused services. Even though it operates only as a redirect, it remains a high-value domain for the Read the Docs brand, contributing to the platform’s global reach and visibility among the global developer community.
