Answers that name a competitor

If you’re running an ecommerce shop and want domain + hosting + SSL bundled together, I’d strongly favor a managed ecommerce platform over buying traditional web hosting separately.

🥇 My top pick: Shopify

Shopify is probably the best fit for what you described.

With Shopify, you get:

• Web hosting included — no separate hosting account/server to manage.
• SSL included automatically — HTTPS is handled for you.
• Custom domain support — you can buy your domain through Shopify or connect one you already own.
• Ecommerce functionality built in — products, inventory, checkout, payments, shipping, discounts, analytics, etc.
• Automatic updates/security — much less technical maintenance.
• Unlimited hosting bandwidth on Shopify plans. Shopify Shopify

For most small-to-medium ecommerce businesses, I'd choose Shopify unless you have a specific reason not to.

🥈 BigCommerce

BigCommerce is my second choice, particularly if you have a large/complex catalog, B2B requirements, or more advanced ecommerce needs.

It includes free sitewide HTTPS/dedicated SSL, and you can either buy a domain through BigCommerce or connect an existing one. BigCommerce BigCommerce

🥉 WooCommerce + managed WordPress hosting

If you want maximum control and customization, consider WordPress + WooCommerce with a managed host such as SiteGround or Hostinger.

The tradeoff is that you're responsible for more of the technical stack—WordPress, plugins, backups, updates, security, etc. Shopify/BigCommerce handle much more of that for you. iTechGuides

What I'd choose

One important point: don't choose a provider simply because it says "free SSL." SSL is essentially a standard feature now. For an ecommerce store, I'd care more about reliability, checkout security, backups, scalability, payment processing, support, and total monthly cost.

If you tell me roughly how many products you sell, your monthly sales/revenue, and whether your current store is Shopify/WooCommerce/custom, I can narrow this down to the best 2–3 options and what you'd actually pay per month, including domain and SSL.

If your goal is:

Buy one domain → create lots of subdomains → host different sites/apps under those subdomains → manage everything from one account

then I’d prioritize traditional web hosting that supports multiple websites/subdomains, rather than a site builder.

My picks

What I'd choose

Hostinger is probably the sweet spot if you don't want to mess around with servers.

Their current plans support multiple websites under one hosting account, and their Premium and higher plans allow multiple sites/domains. Their current hosting page also includes a domain with eligible plans, SSL, backups, and other hosting features. Hostinger Hostinger

For example, you could have:

yourdomain.com
├── www.yourdomain.com
├── blog.yourdomain.com
├── app.yourdomain.com
├── shop.yourdomain.com
├── client1.yourdomain.com
└── client2.yourdomain.com

You don't need to purchase a separate hosting account for each subdomain.

One important distinction

If you mean multiple subdomains, almost any decent host can do that.

If you mean multiple completely separate domains, such as:

mycompany.com
myproject.com
anotherproject.com

then you specifically want a plan that supports multiple websites/domains under one hosting account. cPanel, for example, explicitly supports managing multiple domains and subdomains from a single account. cPanel & WHM Documentation cPanel & WHM Documentation

If you're technical

I'd actually consider separating the domain from the hosting:

Cloudflare Registrar/DNS + a VPS or cloud host

Cloudflare is excellent for DNS, SSL, CDN, and domain management, but Cloudflare itself says it doesn't provide conventional hosting for most websites (apart from things like Cloudflare Pages). Cloudflare Docs

That gives you something like:

Cloudflare
   │
   └── yourdomain.com
        ├── app.yourdomain.com ──→ VPS
        ├── api.yourdomain.com ──→ VPS
        ├── blog.yourdomain.com → VPS
        └── admin.yourdomain.com → VPS

My recommendation: If you're starting out and want everything simple, go with Hostinger's multi-website plan. If you're building several applications and are comfortable with Linux/Docker, I'd go Cloudflare + VPS instead.

If you tell me how many subdomains you expect (e.g. 5, 20, 100) and whether they're WordPress sites, static sites, or apps (Node/Python/etc.), I can narrow it down to the best plan/provider for you.

For a multilingual site needing country-specific TLD registration (ccTLDs like .de, .fr, .jp, .ca) plus hosting in multiple geographic regions, you’ll usually want a provider with both a broad domain portfolio and a global hosting/CDN footprint. A few options fit:

A common enterprise setup is:

1. Registrar: use a registrar with strong ccTLD support (for example, one account managing .de, .fr, .co.jp, .com.au, etc.). Some registrars advertise thousands of extensions and bulk management features. NiceNIC
2. DNS/CDN: use Cloudflare for global DNS, caching, WAF, and routing.
3. Hosting: deploy workloads close to users: - North America → US regions
4. Europe → EU regions
5. Asia-Pacific → Singapore/Japan/Australia regions
6. Localization: map: - example.fr → French market
7. example.de → German market
8. example.jp → Japanese market

or use language/country subfolders if that better fits SEO. Shopify Help Center

If you want a single vendor rather than a best-of-breed stack, I’d shortlist:

• OVHcloud for global infrastructure + domains
• IONOS for simpler bundled management
• GoDaddy for the widest consumer/business domain ecosystem
• Shopify if this is an ecommerce multilingual site

The right choice depends on whether your priority is SEO with ccTLDs, lowest operational complexity, or maximum global hosting performance.
