We are in pre-planning for our exit as well. We will be on AWS EKS(perhaps with lambda/ECS mix) by the time our contract is up next March.

Too many issues both discussed here and undiscussed. Also, their upsell approach is stale:

* Public runtime has a 20 min cooldown after 3 app crashes

* Hobby pro dynos don't report container mem limits due to ancient cgroup setups(gotta upgrade to performance M)

* No Dyno sizes between 2.GB and 14GB ?!

Bunch of BS trying to push you towards Enterprise accounts, more expensive dynos, and private spaces(which cost more Dyno units).
