I haven't checked out last backend in a while. From a quick look at their site I can say the following:

- ContainerShip is open source / Last Backend is not. The "brains" of the Last Backend system are managed by Last Backend and run on their servers. With ContainerShip all the critical components run on your own servers so if the centralized ContainerShip Cloud management system goes down, your systems keep working.. Not sure the same can be said for LB.

- ContainerShip already has a fully functional REST API & Command Line Interface for deploying/scaling/managing apps.

- ContainerShip Cloud allows you to do point in time snapshots of an entire cluster which you can then move between clouds/clone/etc.

There is probably more but I would need to dig further into their documentation.
