Replit has enhanced its domain linking capabilities by introducing direct apex domain linking, magic domain linking, and support for multiple domains, alongside updating its domain verification logic. The new verification process now uses DNS records to improve efficiency and includes daily re-verification to ensure continued accessibility of linked domains. Apex domain linking addresses the limitations around CNAME records at the domain's apex by using a separate proxy with TXT records, enabling users to use A records instead. Magic domain linking allows domains to function like the existing .repl.co domain without needing the repl.co extension, simplifying the process and reducing latency. Additionally, the updated system supports multiple domains pointing to a single repl, each undergoing an independent verification process. These improvements provide more flexibility and reliability for users linking custom domains to their Replit-hosted sites.
