TLDs that are considered as dev or staging:
- *.myftpupload.com (GoDaddy)

- *.ngrok.io (tunneling)
Subdomains that are considered as dev or staging:
- stagingN.* (SiteGround; N is an unsigned int)
- *.staging.wpengine.com (WP Engine)
- dev-*.pantheonsite.io (Pantheon)

Additionally, if your domain is localhost (with any port), it will also be treated as a dev or staging domain.
