I have been using Parse for a couple of years now. Some of my clients are currently on it and is being used in production. The most compelling part of the offering is a well thought out SDK which helps in time to market by reducing the development time. Parse has a lot of potential but unfortunately they will need improve in some areas pretty soon. The first issue is documentation, it is bad. What makes it worse is not being able to build a large enough developer community around the product. If Parse would only listen to the developers using their platform, take constructive feedback and improve their offering it will go long way. The response from Parse when things are bought to attention is much to be desired. Part of the problem is Parse needs to solve is to partner with companies/developers to help out their customers with the common issues that people face when using their platform and concentrate on the real issues of the platform. This should also help them with their support as well, which is bad even for paying customers. I really think Parse can learn from companies before them like Microsoft, Salesforce, Apple on how to go about building a strong developer community around a platform. I also think Parse can help a wider range of customers, like make a serious play in the enterprise market if these issues are looked into.
