n8n AFAIK is a workflow builder whereas at Superblocks, we are an Application builder (in addition to a workflow builder). We enable developers to build user interfaces that "bind" to APIs that they build with this feature.
I've used it a bit and find it to align more with the free form node approach where the lines between them define the "control". I think this approach where we introduce a visual programming language has the potential to change the way the industry views products like these.
There's something about the ability to drag on a try catch, use a native break block in a loop, etc. that feels very "like code".
