Cloud Run is awesome, probably the best "megacloud" container/serverless product. But compared to Heroku it still leaves a lot on the table when it comes to developer experience. Stuff like: long-running workers, crons (they're just fixing this in beta this week), ability to get a shell to run arbitrary commands, having multiple environments, auto-configuration of sql/redis connections. Then if you're doing a "real" production-grade app you have to deal with how you orchestrate multiple cloud run instances behind a load balancer (e.g. frontend/backend) and how you deal with CI/CD across multiple environments for that plus all the problems above. Even Heroku has many of the 2nd class of issues (as do the other PaaS that have copied them). Next-gen PaaS like render or railway solve some of these issues, but then you're left with the most critical Heroku issue - lock-in and inability to extend beyond the closed walls of the platform.

For all these reasons, we're building Coherence (www.withcoherence.com). Our first version actually uses Cloud Run - it sounds like we'd solve a lot of your particular problems! But we are also going to offer AWS/Fargate and other deployment targets - since all these platforms have similar issues at this time. The idea is too package up a solution to these issues that goes from dev to production for real-world applications built by serious teams. To democratize a first-class developer experience without all the compromise.
