How Foundries.io and Memfault differ on target hardware, rollback, deployment and cost.
| Foundries.io | Memfault | |
|---|---|---|
| Type | Managed Linux platform | MCU observability + OTA |
| Targets | Linux + Zephyr | MCU + embedded Linux |
| Deployment | SaaS (FoundriesFactory) | SaaS |
| Rollback | OSTree-based atomic updates with rollback | Cohort-based staged rollout; halt on crash-rate regression |
| How it works | FoundriesFactory 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. | 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. |
