Eclipse hawkBit vs Memfault

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

Eclipse hawkBitMemfault
TypeOSS update serverMCU observability + OTA
TargetsAny (device-agnostic)MCU + embedded Linux
DeploymentSelf-hostedSaaS
RollbackNone built in — the device client decidesCohort-based staged rollout; halt on crash-rate regression
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.Devices upload coredumps, metrics and reboot reasons. Releases go to cohorts, and the crash signal tells you whether to continue or stop — which is the part every other platform leaves to you. OTA is one feature of an observability product, not the whole product.

Best forFull control with no per-device feeTeams who need to know why devices fail

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

Memfault

  • Coredump analysis on constrained MCUs is genuinely hard and they do it well
  • Rollouts driven by real crash data, not hope
  • Strong chip-vendor integrations
  • Paid tiers start far above hobby or small-fleet budgets
  • Observability is the product; OTA alone is an expensive way to buy it

Bottom line

Choose Eclipse hawkBit for full control with no per-device fee. Choose Memfault for teams who need to know why devices fail.
