“We estimate around 200 million [LibreOffice] users, but it’s important to note that we respect users’ privacy and don’t track them, so we can’t say for sure,” said Mike Saunders, an open-source advocate and a deputy to the board of directors at The Document Foundation.

There is still noteworthy interest in LibreOffice as a standalone desktop alternative to paid office productivity suites, said Jason Wong, distinguished vice president and analyst at Gartner. “Usually these are clients seeking to keep their on-premises implementation, given that both Microsoft and Google have focused on their cloud offerings,” Wong said. 

Cost is a factor for evaluating software suites like LibreOffice, Wong said. “The downside is the additional specialized resources and new skills needed to maintain the [software],” he  said.
