ARK Deployer, on May 28: https://deployer.ark.io/
As for ARKVM is no more and instead they'll release something new and better which they call ARK Logic

The following comparison is from parts I picked from their ARK's whitepaper.

How a VM like Ethereum's work,
"Standard Smart Contract architecture where developers deploy versatile and
complex applications tend to require a Virtual Machine of some sort.
This essentially provides the ‘runtime engine’ in which the
applications reside. Virtual machines must run a variety of applications, and this
usually results in a bloated system that requires heavy resources to run simple
tasks."

How ARK Logic works,
"Our solution to this is to deliver more than just automation and distributed relay
execution. We want to give organizations the power to develop their own
application logic, the way they are already used to doing it, by using existing tooling
and developing normal applications that can be deployed on our blockchain
infrastructure via the modular architecture of plugins."
