Mender is an over-the-air (OTA) software update platform for IoT and embedded devices. It updates full OS images, applications, containers, AI models and peripherals on Linux and real-time operating systems, including air-gapped devices. Mender is delivered as a hosted service, or customers can run the open-source server on their own infrastructure. The vendor states that it is built on open source, and the client is licensed under Apache 2.0.
Mender is developed by Northern.tech, which lists offices in Oslo, Palo Alto and Shanghai. Hosted Mender runs as separate regional instances in the US (hosted.mender.io) and the EU (eu.hosted.mender.io); the documentation states that the EU instance is GDPR-compliant. Artifacts are distributed through Cloudflare's network, and European Enterprise customers can ask sales to keep artifacts within Europe. Self-hosting gives a European organisation full control over device data and update artifacts.
