What are the EmEditor subdomains?

On April 2026, we have unified all website domains to a single, emeditor.com domain. This is a list of all subdomains for our websites.

  • www.emeditor.com, de.emeditor.com, jp.emeditor.com, ko.emeditor.com, zh-cn.emeditor.com, zh-tw.emeditor.com: EmEditor homepages
  • support.emeditor.com: Emurasoft Customer Center
  • download.emeditor.com: EmEditor downloads
  • help.emeditor.com: Help pages
  • stripe.emeditor.com: Payment page

The domains emeditor.org and emeditor.info now redirect to the help pages and downloads. Existing URLs with these domains will continue to work.
