+- **Visual development** enables developers to be more productive than they can
+  be through code.
+
+- **Workflows and pipelines** can be designed in the Hop Gui and run on the Hop
+  native engine (local or remote), or on Spark, Flink, Google Dataflow or AWS EMR
+  through Beam. _Design once, run anywhere._
+
+- **Lifecycle Management** enables developers and administrators to switch between
+  projects, environments and purposes without leaving your train of thought.
