Why Mender?

Ease of use

Better than homegrown

Mender removes the vast effort of building and maintaining a homegrown solution or cobbling together an assortment of tools. Focus on your product. Leave OTA updates to us.

User friendly

Mender comes with extensive documentation, an intuitive UI, and a test environment where you can deploy your first update within 1 hour.

High quality

Mender has more than 70% test coverage and a growing open source community that is continuously testing, reviewing and improving the product.

Avoid bricked devices

Automated rollback support so your devices will always come back online, even in cases of power loss or data corruption while the update is being deployed.


Built from the ground up with security in mind, Mender enforces secure HTTPS connections and has zero open ports on the embedded device.


Open source

No vendor lock-in

Mender is the only end-to-end OTA tool with both the server and client open source (Apache 2.0), giving you flexibility and freedom.

No rip-and-replace

There is no full-platform, OS or toolchain rip and replace - integrate Mender into your existing development workflow.

Support & services

The Mender management server and client is fully open source and free to use.

If your devices have strict uptime requirements, or if fast problem-resolution is a priority, Mender offers subscription support in order to help you quickly resolve any questions or issues that arise.

Mender also provides professional services to get you off the ground with automated OTA updates quickly.
