uCoz is a free web hosting with a built-in content management system. The modules of the uCoz CMS can be used together to build a fully featured website, or separately, e.g. as an online shopping platform, blog, webforum etc. As of March 10, 2014, there are more than one million websites created in the uCoz system.[3] uCoz is among the top sites for Russian-speaking users according to Alexa Internet.[4]


Initially, the basis of the service development was formed by the combined experience of several developers, which consisted in previous work over different services such as polls, free guestbooks and, more importantly, a professional CMS script (WoCatalog Pro). On the 29th of October 2005, after almost a year of development, uCoz announced the Russian version of the system. In June 2007, the English version of the system was officially announced, and in August — the German version. Currently, uCoz is also available in Azeri, Spanish, French, Arabic, Hungarian, Romanian, Swedish, Polish, Portuguese, partially in Hebrew, Latvian, Ukrainian, and Georgian languages.

uCoz is backed by the Mail.ru group, has its headquarters in Moscow, Russia and other offices in Sankt Petersburg, Rostov on Don, Kazan and Cherkassy, Ukraine.

Being a SaaS system, uCoz has the features of this type of platform like closed source code, but with the availability of running server-side scripts like JavaScript. Also, it has the unavailability of running databases (all this is possible within Web 3.0 PaaS concept), which is balanced out by a great number of built-in system capabilities. Static HTML pages can be used but are not recommended; there are some limitations on their usage and uploading.[citation needed] Also, the system is fully HTML5 and CSS3 compatible, giving developers complete freedom in development.
