Yes, back-end integrations seem to be one of the main reasons why users decide to adopt us. Being able to add their own components is also one of the big reasons. Also, being able to customize the front-end without limits also reassures developers who were mainly interested in using back-end integrations.

I really like your point of vue on the marketplace approach and tend to agree. Most users will want off the shelf elements that they can customize easily (especially marketers). We will start working on the marketplace this Spring.

As for react in vue, our problem really lies into the pre-rendering -> the main problem is that we have react in a vue.js environment which can create performance problems and conflicts between the two frameworks.
