A Web Framework built on top of Qt, using the simple and elegant approach of Catalyst (Perl) framework.

Qt's meta object system is what powers the core of Cutelyst, it allows for introspecting controller's methods signatures and generate matching actions that can be invoked later.

Don't trust us on being fast, check out the most comprehensive web framework benchmarks by TechEmpower http://www.techempower.com/benchmarks/
