About Duda

Most builders are bought by the person whose name is on the door. Duda usually is not. The platform was built in 2009 for agencies, hosting companies and software vendors that produce and maintain client sites in volume, so a page carrying it was very likely delivered by an intermediary rather than assembled by the business it advertises.

The distinction changes what a detection means. Finding a self serve builder means finding a small business owner. Finding this platform usually means finding two parties at once, the business on the page and the agency or reseller that put it there, and the second party is the one holding the contract and the renewal decision. Duda sells seats and white label deployments rather than individual sites, so a single customer can account for a long tail of unrelated domains that share nothing except their builder.

As of October 2026 the platform is detected on 58,166 sites. 53,717 of them are in Germany and .de is the extension we record alongside it most often, a pattern that says more about which agency networks resell the product than about where the vendor itself sits. The client side code is JavaScript, and the output is a hosted page rather than a downloadable template, so sites in the list stay on the platform for as long as the reseller keeps paying.

Several kinds of buyer ask for the cohort. Agencies scouting acquisitions want to know which competitors run their client base on a shared platform, because a common platform is what makes a book of client work portable. Integration and plugin vendors want the installed base before committing to build for a marketplace. Competing platforms want the accounts where content has gone untouched for a long stretch, which is a cheap early signal that a client relationship has cooled. A per domain lookup confirms a suspicion about a single site. The full list turns the platform into a market you can size, segment by country and extension, and cross reference against the payment, analytics and commerce tools running on the same pages.

White labelling is the honest limit here. The platform is designed to be invisible, and a reseller who serves the site from their own domain, strips branding and proxies assets can reduce the fingerprint to very little. Our count should be read as the sites where the platform still identifies itself in markup, asset paths or response headers, which is a large and workable population but not the whole book of business. Detection also cannot tell you which agency owns which site, only that agency shaped delivery is present.
