Eclipse hawkBit vs Mender

How Eclipse hawkBit and Mender differ on target hardware, rollback, deployment and cost.

Eclipse hawkBitMender
TypeOSS update serverLinux OTA
TargetsAny (device-agnostic)Embedded Linux
DeploymentSelf-hostedSaaS + self-hosted
RollbackNone built in — the device client decidesA/B partitions with automatic rollback on failed boot
How it worksA rollout and artifact management server, deliberately not a device agent. It handles targets, distribution sets, staged rollouts and reporting over a plain HTTP protocol; how the device applies the update, and whether it can roll back, is entirely your side of the contract.Writes the new root filesystem to the inactive partition, reboots into it, and rolls back automatically if the device fails to check in. Delta updates and phased rollouts sit in the paid tiers; the update mechanism itself is open source and self-hostable.

Best forFull control with no per-device feeLinux fleets that must never brick

Eclipse hawkBit

  • No per-device cost at any scale
  • Mature rollout and campaign model
  • Device-agnostic — pair it with any updater
  • You operate it, back it up and secure it
  • No device agent — you supply the other half

Mender

  • A/B rollback is the safest widely deployed model
  • Genuinely usable open-source edition, not a crippled demo
  • Self-host or hosted without changing the client
  • Dual partitions cost you flash — roughly double the rootfs
  • Not designed for constrained MCUs

Bottom line

Choose Eclipse hawkBit for full control with no per-device fee. Choose Mender for linux fleets that must never brick.
