.dev is a Google Registry TLD aimed at developer-facing projects, docs sites, and open-source landing pages. The whole TLD is on the HSTS preload list, so every major browser will refuse plain HTTP. A valid TLS certificate is mandatory before the site loads.

Things to know
Local dev workflows that mock*.dev hostnames can collide with this TLD now that it’s on the public DNS. Browsers will try to look up myproject.dev against the public registry instead of 127.0.0.1 unless your /etc/hosts is set explicitly.
