Memfault

Memfault brings observability practice to embedded hardware, and its framing is precise about the problem: fix defects before customers find them, and go from fault found to shipping a fix before the customer notices. Server software has had crash reporting and performance monitoring for years, while embedded devices have historically failed silently in the field, with engineers learning about problems through support tickets or returned units. Memfault closes that gap.

The capabilities map directly onto that goal. Performance monitoring gives real-time visibility into deployed device behaviour. Debugging and diagnostics handle post-mortem analysis, with coredump capture that lets a crash on a device in a customer's home be examined as if it had happened on a desk. Log management and analytics aggregate device logs, product analytics cover usage, and OTA updates ship the fix once found. The vendor claims it is the only platform able to monitor every device you make, from BLE sensors to ethernet cameras, which spans a very wide range of hardware capability.

Platform support covers Android, embedded Linux and microcontrollers. MCU support is the demanding one, since a microcontroller may have kilobytes of RAM and no filesystem, which makes conventional monitoring approaches unusable and is why most observability tools stop at Linux. Named use cases are smart home and access control, connected video and connected audio.

The commercial argument is stated in business terms rather than engineering ones: improve customer satisfaction, lower service costs and meet uptime targets. Service cost is the measurable one, since field visits and returned units are expensive. A sandbox is available to try before buying, alongside docs, webinars, coredump sessions and case studies. Pricing is published from 3,495 dollars.
