Node-red also has a lot of connectors, from messaging eco systems to databases and is very flexible. If you hit a wall to the available node then you can always hand code Javascript in a function node.
The Raspbian Distro comes with Node-red pre-installed. Fastest and cheapest way to give it a try.

Node-RED seems similar and looks like it has a nicer interface (I've not tried it though).
