Well, there's an open-source API-clone of appengine...

Read the project’s introduction
AppScale GTS
AppScale GTS is an open source serverless platform for building and running scalable web and mobile applications on any infrastructure.
The platform enables developers to focus solely on business logic in order to rapidly build scalable apps, cleanly separating it from deployment and scaling logic. It allows operations to provide a consistent, tunable environment that can simplify running and maintaining apps on multiple infrastructures. The business will benefit from faster time-to-market, reduced operational costs, maximized application lifetime, and the flexibility to integrate with new or existing technologies.
AppScale GTS is open source and modeled on Google App Engine APIs, allowing developers to automatically deploy and scale unmodified Google App Engine applications over public and private cloud systems and on-premise clusters. It currently supports Python, Go, PHP and Java applications. The software was developed by AppScale Systems, Inc., based in Santa Barbara, California, and Google. In 2019, the company ended commercial support AppScale GTS, however the source code remains available in this GitHub Repo.
Why Use AppScale GTS?
The goal of AppScale GTS is to provide developers with a rapid, API-driven development platform that can run applications on any cloud infrastructure. AppScale GTS decouples application logic from its service ecosystem to give developers and cloud administrators control over application deployment, data storage, resource use, backup, and migration.

21 sourceswell there is https://github.com/AppScale/appscale which probably has some kind of layer on top of cassandra that will emulate it.
but it's a really big project... (But you can run just the Datastore: https://github.com/AppScale/appscale/tree/master/AppDB)
In FoundationDB Document LayerI think Google Cloud Platform looks solid. Their alternative to EC2 is Google Compute Engine.
If you want stuff taken care of for you, Google App Engine is great. I'll note that I haven't deployed anything to production, only played around with it for fun. The flexible environment is still in beta, so it doesn't provide any SLAs. For a large serious production project that's a big factor to consider. If it's a small app, I think the "magic" is worth it. But I've only hacked together toy node APIs for SPAs.
For data storage, Cloud Datastore looks great. If it seemed to fit my problem, I'd probably go with that. The big problem with that is vendor lock-in. It has an emulator for testing and development. If you had to migrate away from it, I think AppScale [0] has an open source alternative, but I'm unable to vouch for its quality. If I were

creating a serious long-term project, a Postgres instance on RDS would probably be my other choice. Google has Cloud SQL, but my experience with MySQL hasn't been as pleasant as with Postgres. I don't know how they compare "at scale".
In my job we use AWS in production, and I've slowly learned my way around it. I'd say I'm still a total beginner with AWS. Although I've only used GCP "for fun", from my limited experience and my perspective as an application developer, it seems more easily approachable / accessible.

There is an opensource reimplementation of App Engine's interface. That said, I have no clue about its completeness or buglessness.

There is this: https://www.appscale.com/
It's an open source implementation of the App Engine APIs. The website doesn't make it very clear but the source is on Github: https://github.com/AppScale/appscale
In Why Google App Engine Rocks: A Google Engineer’s TakeDatastore isn't proprietary, AppScale (http://www.appscale.com) has built a handy OSS version which runs above Cassandra.

Disclaimer: I work at GCP, so I'm geeked about open approaches to solving problems :)
In Node.js on Google App Engine Goes BetaIt's worth noting that there is an open source implementation of AppEngine, for projects that want to self-host:

Will open source projects that reflect Google's internal infrastructure follow suite ten years later of it being mentioned in a research paper or public beta?
