I love idea of Nextcloud, but its overall concept of doing everything, but nothing well enough was one of the reasons I've decided to build S3Drive. We squeeze most of the "file-management" experience out of the protocol itself. That means that all you need to self-host is the S3 storage server (e.g. MinIO)... but if you don't feel like it just yet you can buy S3 from anyone else (e.g. Backblaze / Wasabi / Synology / Cloudflare etc.) and enable 100% Rclone compatible E2E encryption to protect your privacy.
