Why people self-host Seafile
Seafile is a strong file-sync choice when performance, efficient libraries, and reliable desktop sync matter more than an app ecosystem. It is often simpler than a full collaboration suite for pure file workflows.
The tradeoff is a more focused product with less office-suite breadth. Test library restore, client behavior, and storage growth on representative folders.
Deployment notes
Seafile is listed with support signals for linux, docker. Check the upstream documentation before exposing it to the internet, review authentication defaults, and keep backups outside the primary host.
