Interesting. Sounds like Parse wasn&#x27;t nearly as mature as they made themselves out to be. I&#x27;d have expected at least PaaS levels of stability—by, at the very least, pinning each client to a particular API version with guaranteed semantics until they choose to shift to making requests on higher-versioned equivalents of each API resource.<p>A thought: if &quot;Parse&quot; had originally just been this open source Parse Server offering, and you had taken that and plopped it on e.g. Heroku, would that have been a better deal for you? Seems like &quot;apply FOSS to PaaS to get BaaS&quot; wouldn&#x27;t have been <i>that</i> much more hassle, operations-wise; and you would have been able to upgrade the backend only when you liked, rather than having it mutated out from under you.
