A safe home for all your data

ownCloud provides what the name implies: a AGPL-licensed file sync & share server written in PHP and with clients for most mobile devices and a powerful extension system. You run it on your own server or look for one of our providers. With over 8 million users and hundreds of developers, we're by far the biggest game in town when it comes to open source file sync & share tech. And the coolest ;-)
