Domain
You might say
I want people to be able to type an easy-to-remember name to open my website.
Give a website a human-readable addressA domain name is the address people type, such as example.com. It is registered separately from the server that hosts the site and points to that service through DNS. Renew it on time, protect the account, and decide which subdomains each service uses.

Find why example.com does not open the production site: confirm deployment, then check the host's domain binding and required DNS records. Do not change unrelated records or rely on URL forwarding. Verify example.com and HTTPS afterward.

Anatomy
app.vibeui.dev
The prefix configured under the registered domain name, such as app, blog, docs, is used to distinguish different services
Registry rules determine which level can be registered. For example, vibeui.dev may be registrable at that level, depending on the suffix.
The final part of domain names such as .com, .dev, .cn, etc.; registration policies, prices and audience familiarity will change after the suffix.
Variants
Commercial
vibeui.com
Audience familiarity is high, but still combined with name availability and brand choice
Dev & App
vibeui.dev
Commonly used in technology and application products; use HTTPS. Configure a valid certificate before deployment, and enable HSTS only after HTTPS is working correctly.
China
vibeui.cn
It can be evaluated when targeting Chinese users; registration and online requirements need to be checked according to the registrar and hosting region.
AI & IO
vibeui.ai
Commonly found in AI and tool products; compare first-year price, renewal price and transfer-in and transfer-out rules before purchasing
