balena vs Golioth

How balena and Golioth differ on target hardware, rollback, deployment and cost.

RollbackContainer-level: previous image kept, restarted on failureManual release targeting; rollback by publishing a prior artifact
How it worksbalenaOS runs a container engine, so a release is a set of container images rather than a system image. Updates are pulled with binary deltas and applied per service, which makes them small and quick — at the cost of running a container runtime on every device.One consumption meter instead of plans: $0.25 per connected device per month, $0.0095 per megabyte of OTA traffic, and separate rates for logs and streaming data. Every account gets the same features, which makes small fleets cheap and makes cost forecasting arithmetic rather than negotiation.

Best forFleets whose teams already think in DockerZephyr projects that want predictable unit cost

balena

  • Deltas make updates small and fast
  • Familiar workflow for anyone who ships containers
  • Device SSH, logs and remote access built in
  • Container runtime is real overhead on small hardware
  • Per-device pricing climbs steeply past prototyping

Golioth

  • Cheapest credible option at small and mid scale
  • Cost is calculable before you commit
  • Deep Zephyr integration
  • Zephyr-centric — other RTOSes are less travelled
  • Metered bytes need watching on chatty fleets

Bottom line

Choose balena for fleets whose teams already think in docker. Choose Golioth for zephyr projects that want predictable unit cost.
