VERDICT

Should I use ownCloud?

Share files and folders, easy and secure - owncloud.com

Depends. Buy it if you need self-hosted, compliance-driven file sharing and have IT staff to patch and monitor servers. Skip it if you're a small team or individual — managed storage like Dropbox, Google Drive, or Nextcloud fits better.

Confidence

Medium. Based on 30+ public sources; many review snippets were truncated, so user quotes are partial.
