AeroFS vs ownCloud: What are the differences?
Developers describe AeroFS as "Enterprise File Sharing and Collaboration. Like Dropbox, but behind your firewall". Your files are never stored on AeroFS servers. AeroFS enables you to share and collaborate while keeping full control over your data, even when sharing with your customers, vendors, and partners. On the other hand, ownCloud is detailed as "Open source self-hosted web apps with sync clients and sharing". It is an open source, self-hosted file sync and share app platform. Access & sync your files, contacts, calendars & bookmarks across your devices. You decide what happens with your data, where it is and who can access it.
AeroFS and ownCloud belong to "File Storage" category of the tech stack.
