Plug and play CS

Pre-compiled binaries in both the most widespread package systems—RPM and DEB—make FRED very easy to deploy. The only steps you have to take are: performing the package installation, setting the domain you want to register and launching the system. That's it. FRED also comes with a full-featured command line and a development library (Python) for easy integration into other systems. So Registrars can benefit from Plug & Play, too.

Based on latest technologies

The system was written from scratch in 2006 and the software has been being improved and updated constantly since then. That ensures latest technologies are used to provide maximum performance, customizability and innovative features. Yet FRED is based on industry standards such as Extensible Provisioning Protocol (EPP) for Registry–Registrar communication (real-time over TLS secured TCP connection). The standards are even extended to provide sophisticated features and to increase user friendliness.

High performance

FRED is optimized for high performance—it can handle roughly 200 registry-changing operations per second (registrations, updates, renews or deletes) with millions domains within the Registry on common server-grade hardware (tested up to 20 millions domains). Such performance together with easy scalability options provides longer hardware and software life cycle ensuring no problems when the Registry grows in the future.


There is a lot of different modules and components that FRED consists of. Nice feature is that you can only install modules that you want to use. Different components of FRED can be even installed on different servers which provides better scalability and possibility of specification of different security policies for different parts of system. Of course, FRED is also capable of running in single server configuration.
