Domain Name
A domain name is a human-readable address for a website, like vibecoding.com or myapp.io. It replaces the hard-to-remember IP address of the server hosting your application. For vibe coders, getting a custom domain is the step that makes a side project feel like a real product.
Example
Your app is live at myapp.vercel.app, but you buy myapp.com for $12/year and point it to your Vercel deployment. Now users visit myapp.com instead — it looks professional and is easy to remember.
A domain name is your project's identity on the internet. It's often the first thing you set up when turning a side project into something real.
How Domain Names Work
User types myapp.com → DNS looks up the address → Routes to your server → App loads
DNS (Domain Name System) is like the internet's phone book — it translates names to server addresses.
Where to Buy Domains

Choosing a Domain Name
- Keep it short — Easier to type and remember
- Match your product name — Consistency builds trust
- .com is still king — But .io, .app, .dev work well for tech products
- Avoid hyphens and numbers — Hard to communicate verbally
- Check availability early — Good names go fast
Connecting to Your App
- Buy the domain from a registrar
- Add DNS records — Point the domain to your hosting provider
- Configure in hosting — Tell Vercel/Netlify about your custom domain
- SSL is automatic — Most platforms handle HTTPS for you
The Psychology
A custom domain signals legitimacy. Users trust myapp.com more than myapp.vercel.app. If you're charging for your product, a custom domain is essential.
