Open Source Synology Alternatives
Find open-source alternatives to Synology DSM for home and business NAS. Self-host file storage, backups & Docker apps on any hardware you choose.
Synology provides NAS hardware and DiskStation Manager (DSM), a polished proprietary operating system for centralized file storage, backup management, media streaming, Docker containers, and smart home integration. Synology NAS devices are widely regarded for their user-friendly interface, reliable performance, and strong ecosystem of first-party packages like Synology Drive, Surveillance Station, and Active Backup for Business. They serve home users, small businesses, and enterprises alike.
Users look for open source alternatives to Synology DSM to repurpose existing hardware, avoid the premium cost of Synology-branded NAS units, or gain access to the full Linux environment beneath the interface. Open source NAS platforms run on commodity server hardware and offer equivalent capabilities—SMB/NFS file sharing, RAID configuration, ZFS storage pools, Docker application hosting, and remote access—without hardware vendor lock-in.
