What is web hosting?

Last modified: November 4th, 2026

Web hosting is where, after a successful build, all your files are stored on a web server and made available to the public on the Internet. You can host your Site through CloudCannon or an external service.

To serve your Site on your own address, you need a domain name, which you can purchase from any domain registrar.

  • Domain name — The address used to access a website (e.g., cloudcannon.com).
  • Domain registrar — A third-party company that sells and renews domain names. The registrar records who owns each domain, and which nameservers answer DNS questions about it (e.g., Cloudflare Registrar, Namecheap).

The domain name of your website appears in the URL.

A diagram of a URL shows labels for protocol, subdomain, domain, top-level domain, subdirectory, slug, and path.

CloudCannon automatically assigns a free domain name to each Site, called a Testing Domain, which you can use to preview your Site content live and share it with Organization Members. To serve your Site on a personal or business domain name, you connect it as a Custom Domain. For more information, please read our documentation on what a Testing Domain is and what a Custom Domain is.

Hosting on CloudCannon#

A developer, or anyone in your Organization with permission to manage Custom Domains, sets up hosting on your own domain. To host your Site on your own domain through CloudCannon, they:

  • Connect a Custom Domain to your Organization.
  • Choose a DNS provider for it: CloudCannon DNS or external DNS.
  • Add the Custom Domain to your Site, so CloudCannon serves your Site on one of its Subdomains (e.g., example.com or docs.example.com).

For more information, please read our documentation on connecting a Custom Domain to your Organization and adding a Custom Domain to your Site.

CloudCannon issues and renews an SSL Certificate for each Subdomain automatically, unless you upload your own. For more information, please read our documentation on what an SSL Certificate is.

For more information on how these pieces fit together, please read our documentation on how hosting works on CloudCannon.

Do you want to host on CloudCannon?

Hosting your Site on CloudCannon might be right for you if you want to keep your hosting settings on the same platform you use to edit your content.

By default, CloudCannon serves Sites hosted on CloudCannon through a Cloudflare Content Delivery Network (CDN). Some Subdomains skip CloudCannon's CDN, depending on the hosting option chosen for each Subdomain and on your DNS Provider. A CDN is a globally distributed network of servers that improves your Site's loading time by caching your content. Visitors to your Site can then access a cached copy from a geographically closer server.

Whenever you update your Site, your hosting provider must also update these caches to prevent visitors from seeing out-of-date content. CloudCannon uses cache busting so that every time you update the content on your Site, CloudCannon will refresh all the cached copies as well.

If you don't want to host your Site on CloudCannon, you can use an external provider without interrupting your ability to edit your content in CloudCannon. For more information, please read our documentation on what external hosting is.

If you want to host your Site externally, you can also disable builds on CloudCannon. For more information, please read our documentation on what Headless Mode is.

Which combination of DNS Provider and SSL Certificate is right for your Site?

Unless you are familiar with web hosting, we recommend reading our documentation on what DNS is and what an SSL Certificate is before selecting a DNS Provider or SSL Certificate type.

DNS and SSL often work hand-in-hand. The correct combination of DNS Provider and SSL Certificate will depend on your desired Site configuration. Here are a few common examples:

  • CloudCannon DNS and an auto-generated SSL Certificate (recommended) — Manage your domain settings and website security in the same place as your content. CloudCannon keeps your DNS records up to date, and issues and renews a certificate for each of your Subdomains.
  • External DNS and an auto-generated SSL Certificate — Manage your domain settings through a third-party service (e.g., Cloudflare), and let CloudCannon issue your SSL Certificates. This option is good if you have existing DNS infrastructure.
  • CloudCannon DNS and a Custom SSL Certificate — Manage your domain settings through CloudCannon, and get your SSL Certificate from a third-party service.
  • External DNS and a Custom SSL Certificate — Manage your domain settings and get your SSL Certificate through third-party services. This option is good if you have existing DNS infrastructure and security policies that require you to have an SSL Certificate from an internally approved authority.
