Very easy to use and get set up. The team there is also more than willing to help tackle tricky configuration edge cases (thanks for the multi-environment support!!!). App development within Superblocks is very straightforward -- reminiscent of the best parts of developing Windows desktop applications in Visual Basic or Delphi: just drag, drop, and link actions to functions and queries.
The support for various scripting languages for transforming data is huge as well. Building out a complex tool that merges data from several different sources can be a huge pain in our system internally, but once your data sources are connected, it's very easy in Superblocks. Highly recommend this tool for teams with problems that could be solved by internal apps leveraging this data fusion.
