About Nette Framework

Most web frameworks have no nationality. Nette Framework has one, and the data makes it impossible to miss.

As of October 2026 we detect the framework on 11,878 sites, and 7,387 of them sit in Czechia, with the .cz zone carrying a matching concentration. Clustering that tight is rare among technologies of similar reach, and the explanation is not a technical one. The framework was released in 2006 under the MIT licence by Nette Foundation, it runs anywhere, and nothing in it favours a particular market. Its documentation, its books, its conference circuit and its hiring market grew up in Czech instead, and reach follows the language a community argues in rather than the licence file.

Nette Framework is written in PHP and aimed at building applications rather than at publishing pages. Components, dependency injection, the Latte templating engine and the Tracy debugger define the developer experience, and strong defaults around forms, tokens and escaping have been a selling point for as long as the project has existed. Teams reach for it when they need custom business systems, portals, booking flows and internal tools, which is the opposite end of the market from an off-the-shelf content system installed in an afternoon.

Detection therefore tells a commercial researcher something quite specific. A domain built on Nette Framework was very likely delivered to order by a Czech or Slovak development team, carries a budget for custom work, and has an in-house or contracted maintainer behind it. Sites in this population are not template purchases, and the buying decisions behind them run through developers and technical directors rather than through a marketing manager choosing a theme.

The framework does not announce itself, and the honest caveat on the count follows from that. No banner and no version string appear in a normal response, so detection rests on incidental fingerprints such as cookie naming, asset paths, form token patterns and error page behaviour. A hardened production deployment can be invisible to all of them, which means the real installed base is larger than the figure published here, and it is also why no version breakdown is offered for this framework at all. Absence from the list is not evidence that a site avoids it.

Who wants the export follows from everything above. Development agencies and recruiters use it to size a national market that no jobs board measures properly, software vendors use it to decide whether building and maintaining an integration is worth the effort, and security teams use it to scope exposure when an advisory lands on a framework whose users are concentrated in one jurisdiction. A lookup on a single domain settles an argument about how one site was built. The export answers how large the Czech custom-application market really is and which companies are inside it, and no amount of checking domains one at a time will produce that answer.
