Seafile is an open-source file synchronization and sharing platform founded in 2012 by Daniel Pan and Jonathan Xu, who began developing the underlying sync-and-share concepts as graduate students several years earlier. The company operates as a globally distributed team with offices in Beijing, China, and Singapore.
Unlike consumer cloud storage services, Seafile is designed to be self-hosted on an organization's own servers or private cloud, giving IT teams control over where data lives. It is commonly compared to other self-hosted file sync platforms such as Nextcloud and ownCloud.
Key Features
The free Community Edition provides core file synchronization and sharing, desktop and mobile clients, and web-based file management. The paid Professional Edition adds enterprise administration tools including an advanced admin console, detailed audit logs covering logins, file access, updates and deletions, and integration with LDAP, Active Directory and SAML for centralized authentication.
Professional Edition also supports server clustering for high-availability deployments, which is aimed at larger organizations that need Seafile to scale across multiple servers with minimal downtime.
Pricing
The Community Edition is free and open source. The Professional Edition is free for up to 3 users, offered at a flat 100 US dollars total for up to 9 users, and then priced per user starting around 48 US dollars per user for 10 to 249 users, scaling down for larger deployments to roughly 35 US dollars per user for 750 to 999 users.
Custom pricing is available for deployments of 1,000 or more users. Educational institutions receive a 50 percent discount and public sector organizations receive 25 percent off Professional Edition licensing.
