## What it is
Mender is an open-source over-the-air (OTA) software update client for IoT and embedded Linux devices, part of a client-server platform for fleet management. It provides atomic A/B image-based deployments with automatic rollback, plus support for application, container, and delta updates.

## Use cases
- update firmware on embedded linux devices over the air
- deploy os images to a fleet of iot devices remotely
- avoid bricking devices with atomic a/b updates and rollback
- manage phased rollouts of software to device groups
- update devices without a server via standalone mode
- remotely troubleshoot and access devices in the field
- integrate ota updates into yocto or debian builds

## When to choose
- you need robust, atomic OTA updates for embedded Linux or Zephyr devices
- you want automatic rollback on failed updates with A/B partitions
- you manage a fleet of devices and need grouping, phased deployments, and delta updates
- you want an open-source, self-hostable update manager with commercial support options

## When to avoid
- you need OTA updates for Android devices, which are not yet supported
- you only need simple package updates on general-purpose servers rather than embedded devices
- you require a lightweight updater without a client-server architecture

## Facets
- artifact type: application
- maturity: stable
- function: deployment, monitoring, security, configuration-management, developer-tools
- domain: iot, embedded-systems, self-hosted
- platform: embedded, iot, cross-platform
- tags: ota-updates, fleet-management, a-b-partitions, rollback, delta-updates, yocto, zephyr, device-management, devops, automation, linux
