Mender is an open-source (Apache 2.0) project to address over-the-air (OTA)
software update management for Linux-based IoT devices. When we researched
this five years ago, there were no open-source end-to-end (device-to-server)
options to manage the lifecycle of OTA updates for connected devices.
Some open-source options were available, but they either had a proprietary
management server, or they were client-only and required integration with
another back-end server.
