OnlyOffice software suite

OnlyOffice, formerly known as TeamLab, is an open-source office software suite developed by Ascensio System SIA. The company was founded in 2009 and is headquartered in Riga, Latvia. The brand specializes in providing online and desktop document editors, collaborative platforms, and project management tools as an alternative to dominant proprietary office suites.

While the brand has its roots in developers from Russia through its original parent structures, it is now globally operated as a Latvian legal entity under the name Ascensio System SIA. The manufacturing (software development and coding) primarily takes place in Europe. The brand emphasizes open-source transparency and has successfully expanded into the global market, particularly in Europe and North America, by offering self-hosted solutions for enterprise security.
