Creating a web app is only the beginning — connecting it to a custom domain is a crucial next step. A custom domain not only makes your web app easier to access by replacing complex IP addresses with a memorable name, but it also strengthens your brand identity and builds trust with users.
In this guide, we’ll walk you through the process of linking a custom domain to your web app, especially if you’re using Hostinger Horizons or another no-code platform. We’ll also share tips on choosing the right domain extension based on your app type.
What Is a Custom Domain?
A custom domain is a unique web address that replaces your app’s numerical IP address. It typically includes your brand or app name with an extension like .com, .net, or .app — for example, yourwebapp.com. This human-readable URL is easier for users to remember and adds credibility to your online presence.
How to Connect a Custom Domain to a Web App
The process of connecting a domain can differ depending on the platform you’re using. Hostinger Horizons, for instance, offers seamless domain integration, while other no-code tools may require manual DNS configuration.
Let’s explore how to connect a domain using Hostinger Horizons and other no-code platforms.
Connecting a Domain with Hostinger Horizons
Hostinger Horizons is an AI-powered web app builder that includes everything you need — hosting, email, and domain services — in one platform. You can connect a domain during or after publishing your app.
Option 1: Connect During Publishing
1. Build your web app using Hostinger Horizons.
2. Click the Publish button once you’re ready.
3. A pop-up will confirm your app is live — click Get domain.
4. Search for your ideal domain name and select one that’s available.
5. Click Next and follow the on-screen instructions to complete the setup.
If you already own a domain, you can use it without additional steps after clicking Next. New domain purchases will require payment before activation.
Option 2: Connect After Publishing
Prefer to choose your domain later? No problem. Here’s how:
1. Log in to your Hostinger account and open hPanel.
2. Go to Websites → Websites list.
3. Locate your app and click Change domain.
4. Enter your desired domain name.
5. Click Next and follow the setup instructions.
Note: It can take up to 24–48 hours for your domain settings to propagate. During this time, your domain may not yet direct to your app. If issues persist, Hostinger’s support team is available 24/7.
Connecting a Domain with Other No-Code Tools
Other no-code platforms may not offer built-in domain services, but you can still connect a custom domain by following these general steps:
1. Purchase a domain from a provider like Hostinger.
2. Generate DNS records (usually A or CNAME) from your app builder.
3. Enter these records into your domain registrar’s DNS settings to point the domain to your app’s server.
Make sure to check your platform’s documentation for specific instructions.
Choosing the Right Domain Extension
Your domain extension should reflect your app’s purpose. While .com is the most common, it may not always be available. Here are some alternatives based on your app type:
– .app – Universal option for all web apps
– .io – Ideal for tech startups and SaaS platforms
– .tech – Great for tech-focused products
– .edu – Best for educational and e-learning apps
– .pro – Suitable for professional services
– .co – Short and memorable, perfect for startups
– .dev – Tailored for developer tools and platforms
– .ai – Perfect for AI and machine learning apps
– .cloud – For cloud-based services
– .me – Personal branding, portfolios, or digital resumes
– .health – Healthcare, fitness, or wellness platforms
– .community – For social or interest-based apps
– .travel – Travel planning or tourism apps
Conclusion
Connecting a custom domain to your web app is a simple but essential step in building your online presence. Whether you use Hostinger Horizons or another no-code tool, the process is straightforward and well worth the effort.
