About this app

Seafile is a file synchronisation and sharing platform built around block-level deduplication for fast syncing. It supports file versioning, client-side encryption, and granular team permissions, with desktop and mobile clients for Windows, Mac, Linux, Android, and iOS. People who switch to Seafile consistently point to its sync speed and lower resource use. Block-level syncing only transfers the parts of a file that changed, so it holds up well on large libraries and modest hardware, unlike heavier all-in-one alternatives that can feel sluggish under the same load. The free Community Edition also has no cap on the number of user accounts, useful for anyone sizing it against a per-seat SaaS bill. Three features sit behind Seafile's paid Pro tier: SAML single sign-on, audit logs, and high-availability clustering. Everything else, including OIDC and LDAP login, multi-factor authentication, file versioning, client-side encryption, and the REST API, is free in the Community Edition.
