FAQ – Frequently asked questions
The .DEV TLD is a secure namespace, meaning that HTTPS is required for all .DEV websites. You can register your .DEV domain name now, but in order for it to work properly in browsers you must first configure HTTPS serving by configuring a SSL Certificate with your domain name. For each individual domain contract you'll receive a free SSL certificate, which can be easily set up within your Control Panel after the successful domain registration.
