Over-The-Air Updates

Secure, Scalable OTA Firmware Updates for IoT Devices

Whether you’re adding a new product feature or fixing a bug, keep customers happy with frequent, efficient updates.

Secure, Scalable OTA Firmware Updates for IoT Devices


More visibility for more control

Memfault de-risks over-the-air (OTA) updates with real-time monitoring and controlled releases to help you debug and ship new releases confidently on any platform (MCU, Linux, Android / AOSP).

Speed up incident response time

Quickly respond to security vulnerabilities and only send updates to the devices affected with automatic issue detection and cohort-based rollouts.

Ship new features with confidence

Enable experiments and lower risks. Group devices in cohorts and update each separately with staged rollouts.

Enhance existing features for cost savings

Reduce service costs by implementing features like a new communication protocol to reduce cellular bandwidth usage.



Continuously improve your product

  • Group devices into cohorts
    Split devices into specific groups like beta users, customers facing a bug, or another cohort and only rollout to those that need the fix.
  • Deploy staged rollouts
    Choose to release updates incrementally to 10%, 50%, or any size of your device fleet to test updates before you deploy to all devices.
  • Stop faulty updates with one click
    Get notifications about issues in your updates, and rollback the update with one-click before 100% of your fleet is impacted.

Monitor releases and updates in one dashboard

  • Keep an eye on release adoption
    Track how many devices have installed your release, how many have run into issues, and how many have yet to update.
  • Build a device registry or manage inventory
    Store custom attributes for your devices to monitor releases and view data-driven device and fleet-level metrics.
  • Monitor specific groups with cohorts
    Split devices into specific groups to monitor updates with beta users, customers facing a bug, or another group before you deploy to all devices.

Flexible Full-Stack Architecture

Scale your devices without scaling issues

Memfault is modular, so it works on Android OS devices or ARM-based microcontroller devices running on bare metal or real-time operating systems (RTOS) using any connectivity (WiFi, Bluetooth, LTE, Zigbee, LoRa, etc.). Our three components ensure that shipping and managing millions of devices is no different than one.

Customizable SDK
Customizable SDK

Integrates into your OS and collects diagnostics data from your devices in the field-coredumps, backtraces, registers, logs, and custom metrics.

Robust Cloud Backend
Robust Cloud Backend

Analyzes data to classify the issue, identifies a possible root cause, and recovers items such as variable and function names from binary data.

Intuitive Web Application

Receive alerts about issues directly to your desktop and drill into individual issues along with overall fleet health in dashboards.


What our customers say

“Memfault saves our developers many hours each week and puts better-performing products in the hands of our end users.”

“Because of Memfault, we were able to go to market faster with more confidence in the success of our launch. I wouldn't go to market on an IoT device without Memfault in place.”

“It would take months and significant engineering resources to implement the tooling necessary to get equivalent functionality to what Memfault offers.”

“The interrupt blog posts show a lot of passion and understanding of the embedded development space, and their interest in sustainable firmware development makes me feel there is more to that passion than just pushing a product.”
