Every website you visit is stored on a server somewhere, managed by a hosting provider. Knowing who hosts a site can help you compare providers, troubleshoot performance issues, or simply satisfy your curiosity.
The fastest way to find this information is to run the domain through a hosting detector tool. These tools inspect public DNS and server response data to identify the hosting company, server software, and content delivery network in use.
Once you have the hosting provider's name, you can look up their plans and pricing to see if they might be a good fit for your own project.
Keep in mind that large websites often use multiple providers for different services, such as a CDN for static assets and a separate provider for the core application.
