Is Memfault worth the price?

65/100

Memfault's pricing is on the expensive side for smaller teams, with the Growth tier starting at $3,495/month.

While the Developer tier offers a free entry point, the jump to paid tiers is substantial. This pricing structure is best suited for established IoT companies with significant device fleets and dedicated budgets for observability.

Hidden Costs & Gotchas

Pay-as-you-go beyond 10 dev devices

Limited data retention on lower tiers

User limits can increase costs

Custom features likely cost extra

How Memfault Compares to Competitors

Compared to Particle, which offers a free tier and then scales up with device counts starting around $2.99/device/month for basic features, Memfault's Growth tier at $3,495/month is significantly higher. While Memfault offers more in-depth debugging and OTA, smaller IoT companies might find Particle's more granular, device-based pricing more accessible than Memfault's high entry point, which is more comparable to enterprise-grade solutions like AWS IoT Device Management's advanced features.

Memfault FAQ

How does Memfault handle devices that are not always connected to the internet?

Memfault is specifically designed to work with intermittently connected devices. It can collect and store data locally on the device, then transmit it to the platform whenever a connection becomes available, ensuring no critical diagnostic information is lost.

What types of diagnostic data does Memfault automatically collect from devices?

Memfault automatically collects coredumps, crash logs, bug reports, general device logs, and various performance metrics. It then processes and prioritizes this data to help engineering teams quickly identify and resolve issues.

Can Memfault be used to manage OTA updates for a mixed fleet of devices running different operating systems like MCU, Android, and Linux?

Yes, Memfault is built to unify monitoring and OTA update management across diverse device types, including those based on MCUs, Android, and Linux, allowing for a consistent approach to fleet management.

How does Memfault assist product managers in making roadmap decisions?

Product managers gain visibility into real-world device performance and usage patterns through Memfault's product analytics. This data allows them to prioritize fixes, validate feature performance, and make informed roadmap decisions based on actual field data rather than guesswork.

What mechanisms does Memfault provide to minimize risk during large-scale firmware rollouts?

Memfault offers features like staged rollouts, allowing updates to be deployed to a subset of devices first. It also provides real-time performance visibility during the rollout and a one-click abort function, enabling teams to quickly halt an update if problems are detected.
