Please correct me if i'm way off base, but at the mental model level, it seems like the key difference between this and Zenaton is:
* Support for multiple languages (Zenaton used to, but doubled-down on Node)
* It runs on your own infrastructure (with Zenaton the code runs on your own machines, but the scheduler runs in their systems)
* A deeper focus on resilience (hard to quantify whether Zenaton has this, but it's definitely not emphasised as heavily)
