History.
The developer of the Multitran software is Andrey Pominov, Moscow.
Currently, Multitran is one of the largest and most popular web dictionaries in Russia.
Every day, over 90 thousand people visit "Multitran.ru", and over 1.5 million search requests are processed.
The Multitran base was created by scanning a wealth of paper dictionaries and combining all the translations in one database.
The website historically had a very low budget: according to Multitran's history page, a CPU paid only one dollar served over 4 million hits, and the site had issues with networking and electricity works around the webmaster's house in 2001 and 2002, as well as with growing traffic in 2002–3.
Multitran users arrange offline meetings from time to time, so called 'pow-wows'. Such pow-wows were held in Moscow, St. Petersburg and Kyiv.
In May 2019 the Multitran's website was redesigned, with a gradual transfer of all user-generated data to the new website.
