I see this: [GitHub - mendersoftware/mender: Mender over-the-air software updater client.](https://github.com/mendersoftware/mender)  
It looks like the client open source, but where is the server code?  
In addition, where is the client-server protocol defined in the documentation?

Thank you.  
You mentioned: [https://docs.mender.io/2.4/apis](https://docs.mender.io/2.4/apis)  
Is this the API the mender client is talking to the server? Where is for example the “delta upgrade” API/protocol mentioned?

The binary delta update is not an API. It’s an update module and is documented here: [Robust delta update rootfs](https://hub.mender.io/t/robust-delta-update-rootfs/1144/9)
