Disclaimer: I work for DBOS. But the reason I took the job is because I think we are solving a lot of the problems that make people choose containers over serverless.

We have an open source library called Transact[0] that you can run anywhere, including locally, and get durable serverless with state (and even some observability). Then you can deploy it to our cloud[1] and get reliability, scalability, more observability, and a time travel debugger.
