Started as crash reporting for firmware and grew into OTA — the only one here that tells you why the update went wrong.
MCU observability + OTAMCU + embedded LinuxBy MemfaultSince 2019Open source: Firmware SDK (Apache-2.0)
- Type
- MCU observability + OTA
- How it works
- 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.
- Targets
- MCU + embedded Linux
- Deployment
- SaaS
- Rollback
- Cohort-based staged rollout; halt on crash-rate regression
- Pricing*
- Free to 10 dev devices; from $3,495/mo · pricing page
- Free tier
- Yes
- Open source
- Firmware SDK (Apache-2.0)
- Best for
- Teams who need to know why devices fail
- Notable
- Crash-driven rollout decisions
* Published list pricing at August 2026 (vendor pricing pages, August 2026), not a quote.
Strengths
- 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
- Firmware SDK is open source
Trade-offs
- Paid tiers start far above hobby or small-fleet budgets
- Observability is the product; OTA alone is an expensive way to buy it
- Free tier limited to development devices
