- Hosted builder versus headless CMS plus your own frontend.
- SEO controls, localization and page speed.
- Cost as the team and page count grow.
How we find CMS and website builders
Website platforms leave clear markers: generator tags, asset hosts (cdn.shopify.com, website-files.com), response headers, and DNS records that point the domain at the platform.
Every company on a tool's page links to the record behind the match. DNS is rechecked weekly and websites monthly, so tools a company stops using drop off the list.
