Navigate to codehs.com/test_codehs_domains to visualize the status of your connection to the codehs.io, codehs.xyz, and codehs.me domains. This tool will attempt to connect to each of these domains and display a successful or unsuccessful connection. Check out the list of CodeHS Whitelist Domains here.

These domains are required for CodeHS to function properly. Unblocking codehs.io ensures students can access HTML program output. Access to codehs.xyz ensures that students can view any content created and embedded by the CodeHS team throughout our activities.

By default, student HTML assignments and Sandbox programs, including private programs, are hosted on the codehs.me domain. Blocking this domain will prevent students from viewing their own HTML program output, in addition to any publicly shared programs on the domain. Schools that want to block codehs.me on their network without affecting students' ability to complete assignments should switch to the codehs.io domain instead.
