How to Setup a Subdomain for Your Restaurant's App

Updated 2026-07-06 · Hosting Reviews

Getting a dedicated subdomain for your restaurant's app—think order.yourrestaurant.com—helps keep the main site clean while giving diners a fast, focused experience. In this guide you’ll find the exact tools you need, how to pick the right hosting tier, and a simple workflow to launch your subdomain in under an hour.

What You Need Before the Subdomain Setup

Three things are essential:

1. Domain name – you already own yourrestaurant.com or are ready to register it.
2. Web hosting – a server where both the main site and the subdomain will live. For most eateries, a shared plan from Hostinger (around $3‑$7 / month) or a low‑cost cloud plan ($8‑$15 / month) is plenty.
3. Platform – the software that will run your app. WordPress with a restaurant‑theme, a site‑builder like Hostinger’s Zyro, or a custom HTML/PHP solution are common choices.

Make sure the host offers a free SSL certificate and easy DNS management; Hostinger checks both boxes and adds one‑click WordPress installs, which speeds up the process.

Choosing the Right Hosting Tier for a Restaurant Website

Most small‑to‑medium restaurants don’t need the horsepower of a VPS. Here’s a quick comparison:

• Shared hosting – Cheapest, good for < 100 daily visitors, includes basic security patches and automatic backups. Ideal if you’re just adding a subdomain for online ordering.
• Cloud hosting – Slightly more expensive, scales resources automatically, better uptime during peak lunch or dinner traffic.
• VPS – Dedicated resources, useful only if you anticipate heavy traffic (e.g., a chain with dozens of locations) or need custom server configs.

For a single‑location restaurant, a shared plan from Hostinger will handle menu pages, reservations, and a subdomain for the ordering app without breaking the bank.

WordPress vs. Site Builder vs. Custom Code

Pick the platform that matches your technical comfort:

WordPress – Offers thousands of restaurant‑focused themes, plugins for reservations (OpenTable integration), online ordering (WooCommerce), and SEO tools. One‑click install on Hostinger means you’re up in minutes.

Hostinger’s Zyro Builder – Drag‑and‑drop, no coding, built‑in SEO and mobile‑responsive templates. Great if you want a quick, polished site and don’t need the extensibility of plugins.

Custom code – If you have a developer on staff, you can build a lightweight HTML/JS app and host it under the subdomain. This gives maximum performance but requires ongoing maintenance.

Step‑By‑Step: Creating the Subdomain and Getting Your App Online

Follow these actions on a Hostinger account; the steps are similar on other hosts.

1. Log into Hostinger’s hPanel. Navigate to the Domains section.
2. Add a subdomain. Enter order (or any prefix you prefer) and click Create. Hostinger will automatically generate a sub‑folder like public_html/order.
3. Upload your app. If you’re using WordPress, install it inside the order folder via the one‑click installer. For a custom app, use the File Manager or FTP to upload the files to that folder.
4. Secure the subdomain. In hPanel, enable the free SSL for order.yourrestaurant.com. Hostinger’s AutoSSL will issue and renew the certificate automatically.
5. Configure DNS (if needed). Most hosts auto‑add an A‑record for the subdomain, but double‑check that the DNS entry points to your hosting IP.
6. Test the site. Open https://order.yourrestaurant.com in a browser, verify the menu, ordering flow, and checkout security.
7. Optimize speed. Enable Hostinger’s built‑in caching (LiteSpeed cache for WordPress) and compress images. A fast subdomain keeps diners from abandoning carts.

Once live, add the subdomain link to your main site’s header or footer so customers can easily find the ordering page.

Speed, Security, and Ongoing Costs

Speed matters for conversion: aim for load times under 2 seconds. Hostinger’s servers are located in the US, and you can enable CDN (Content Delivery Network) at no extra cost on most plans.

Security basics include:

• Free SSL (already enabled above).
• Regular backups – Hostinger provides weekly backups on shared plans; upgrade if you need daily snapshots.
• WordPress security plugins (Wordfence, iThemes) if you chose WordPress.

Cost-wise, expect an initial price of $3‑$7 / month for shared hosting, plus any premium plugins or a builder subscription. Renewal rates are typically 20‑30% higher than the introductory price, so budget accordingly.

FAQ

Do I need a separate hosting account for the subdomain?

No. A subdomain lives on the same hosting account as your main domain; you just allocate a separate folder for it.

Can I use the same WordPress theme on both the main site and the subdomain?

Yes. Install WordPress separately in the subdomain folder and select the same theme, or use a multisite setup if you want shared plugins and users.

What if I outgrow the shared plan?

Hostinger makes upgrading easy. You can switch to a cloud or VPS plan with a few clicks, and the migration tools will move your files and databases with minimal downtime.
