Using License for Live / Production, Staging, Dev and Localhost Sites
Your licenses for your production sites can be activated on localhost/staging/dev environments without the need to purchase any additional licenses. Localhost, staging, and development environments won’t get counted toward the license’s maximum allowed sites if its domain name is clearly a dev or staging site.
TLDs that are considered as dev or staging:
*.dev*.dev.cc(DesktopServer)*.test*.local*.staging*.example*.invalid*.myftpupload.com(GoDaddy)*.cloudwaysapps.com(Cloudways)*.wpsandbox.pro(WPSandbox)*.ngrok.io(tunneling)
Subdomains that are considered as dev or staging:
local.*dev.*test.*stage.*staging.*stagingN.*(SiteGround;Nis an unsigned int)*.wpengine.com(WP Engine)dev-*.pantheonsite.io(Pantheon)test-*.pantheonsite.io(Pantheon)staging-*.kinsta.com(Kinsta)staging-*.kinsta.cloud(Kinsta)*.mystagingwebsite.com'(Pressable)
Additionally, if your domain is localhost (with any port), it will also be treated as a localhost domain.
If you want to utilize a license on a dev site that doesn’t fit the criteria listed above you can deactivate the license from within the Account page in the WP Admin dashboard, and then reuse the license.
