Seafile

Against what buyers need

File sync and storage: covers 98% of the checklist. A file sync and share server built around libraries, with a desktop sync client, the SeaDrive virtual drive, mobile apps, share and upload links, version history and libraries encrypted on the client. LDAP, OAuth, WebDAV and ONLYOFFICE or Collabora editing work in the Community Edition, while SAML, audit logs, S3 storage and clustering are in the Professional Edition, which is free for up to 3 users. Paid edition only: admin controls and audit log and external and object storage.
