Regardless, I still find the potential lock-in costs and issues incurred with a proprietary datastore like FireBase to be a total and complete deal breaker.

For truly production-grade systems, relinquishing control over your data stores does not seem like a viable path to better reliability or control for any business with significantly large swaths of data.

If there were a compatible open-source equivalent with easy import functionality for a FireBase dump, I'd be singing a different tune.

Am I missing or overlooking something here? I get the use case for a small project or app, but for mission-critical production, it doesn't seem like a good idea.
