Best open-source File sync & storage

The best open-source file sync tools in the c17.io catalog are copyparty for a share link today, ClovaLink for multi-tenant file management, Syncthing when the folder should live on every laptop with no vendor cloud, and Sync In Server as a Nextcloud-shaped private cloud. Nextcloud itself is on /stacks/nextcloud-files but is not a Crew catalog row, so it is linked as a stack rather than ranked here.

FAQ

copyparty or Syncthing?
copyparty if you want a share link. Syncthing if the job is a live folder on every device with no server in the loop. That is the stack FAQ.
Where is Nextcloud?
Published as /stacks/nextcloud-files and /replace/google-drive. It is not a listed Crew catalog row, so it cannot appear in this ranking.
Are these free?
Open-source licenses; you pay disk and hosting. Template users never pay c17.
How do I deploy it?
Open /stacks/files-you-own. Persist blobs on a Railway volume or S3-compatible store and lock the admin.
