Foundries.io vs Mender

How Foundries.io and Mender differ on target hardware, rollback, deployment and cost.

TypeManaged Linux platformLinux OTA
TargetsLinux + ZephyrEmbedded Linux
DeploymentSaaS (FoundriesFactory)SaaS + self-hosted
RollbackOSTree-based atomic updates with rollbackA/B partitions with automatic rollback on failed boot
How it worksFoundriesFactory gives you a per-customer Linux build with CI, signed OSTree updates, secure boot and a maintained CVE stream. You are buying ongoing platform maintenance — the part that quietly consumes an embedded team a year after launch — rather than an update tool.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 forTeams who do not want to maintain a distroLinux fleets that must never brick

Foundries.io

  • Removes long-term distro maintenance from your plate
  • Signed atomic updates with rollback by design
  • Security-first: secure boot and key handling included
  • No free tier to evaluate quietly
  • You adopt their platform, not just their updater

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 Foundries.io for teams who do not want to maintain a distro. Choose Mender for linux fleets that must never brick.
