Nextcloud vs Seafile
Both are free/open-source alternatives to Dropbox. Here's how they stack up — verified facts, no spin.
Nextcloud
TOP PICKA full self-hosted cloud: files, sharing, and more.

Seafile
Fast, reliable self-hosted file sync and share.
Seafile is an open-source file-sync-and-share platform known for fast, reliable syncing and client-side encryption options. Its Community Edition is self-hostable and a strong choice when raw sync performance matters.
