Swarm for Synology
Self-hosted monitoring for Synology NAS

Every Synology.
One swarm.

Swarm watches every NAS you look after: disks, pools, backups and DSM updates, for every customer, from one portal on your own server.

Adopt

Pair a NAS in under a minute.

Adoption works like UniFi. The NAS shows a pairing code, you type it in the portal and pick the customer. The agent signs every report with its own ed25519 key.

Overview

The whole fleet on one screen.

Which NAS stopped reporting, which volume fills up, which customer needs a call today. The heartbeat shows every report of the last day, a bar per half hour.

Health

Trouble shows up before it hurts.

Pending sectors on drive 2, a pool that lost a disk, a volume that is full within 30 days. Swarm raises a notice with advice, and closes it on its own when the check is fine again.

  • Volumes
  • RAID and pools
  • SMART per disk
  • Temperatures
  • Hyper Backup
  • Snapshots
  • DSM updates
  • Cloud Sync
  • Task Scheduler
  • Certificates
  • Admins without 2FA
  • 30-day forecast

Notices go where you already work:

Backups

Backups you can prove.

Every Hyper Backup and Active Backup task, its last result and its log, and which shared folders have no copy anywhere else.

Restore proof: Swarm drops a canary file in each task, reads it back from the backup and compares it. Cloud backup: one click gives a NAS its own Wasabi bucket and key.

Hands on

Fix it without SSH.

Sign in to DSM and open a root terminal from the portal, over an outgoing tunnel from the agent: no port forwarding, a reason for every session, and a recording.

DSM updates in rings. A new version reaches your test lab first, and the next ring only when the ring before came back healthy.

Quiet hours

All green? Then the bee sleeps.

Quiet hours and maintenance mode keep the pager still. Notices close on their own when a check is fine again, so a green fleet means nobody needs to look.

And when you want to ask instead of click, the built-in MCP server lets Claude and other AI assistants read the fleet.

22 of 22 NAS units are fine · quiet hours until 07:00

Run it

Your server. Your swarm.

One Docker image with SQLite. Open the portal on port 8080, install the package on a NAS and adopt it.

docker run -d --name swarm -p 8080:8080 -v swarm-data:/data \
  -e SWARM_ADMIN_EMAIL=you@example.com \
