There are definitely some similarities. Like in Gomix, the idea of Baqend is to let developers easily build websites, bots and APIs. However, Baqend has a stronger focus on how data is stored and queried, while Gomix is more focused on a rapid prototyping experience inside the browser.
In my opinion, the whole movement about BaaS is all about making things as smooth as possible for developers and shorten the time-to-market to its minimum. What some providers like Parse lost on the way, are the capabilities for small prototypes to grow to large systems. That requires being scalable at both the level of API servers, user-submitted backend code and the database system. And at some point, it also requires letting the user tune things like indices, shard keys and execution timeouts. This is the route we took at Baqend. We do not want to be the simplest solution out there, but we aim to provide the fastest (we use new web caching tricks) and most scalable one (we expose how the database is distributed).
