Paul, good input. The way I look at n8n is that its a great platform for developers and integrators. It has some really great tools such as the HTTP app making custom API calls easy. Zapier is more geared towards integrators and more technically inclined end users by the way it has the vendors package their triggers and actions. However, I have been enjoying their addition of AI as it's pretty much eliminating the need to know regx and even simple scripting. But I recently use their AI integration to create a java script for manipulating some data. All I needed to know is what to ask for. But... I will say its not perfect yet by any means.
What I'd like to see is more print related vendors that have cloud services support these types of platforms. Zapier and Make.com are great examples of easy automation tools that if there was more support by print related vendors it would allow more printers access to automations that make sense for any business. As you point out, the low-code platforms make the integration part very easy, and provide some great tools to build anything from simple task based workflows to more complex conditional workflows.
The only part I think we differ in our thinking is the statement you make about Zapier and n8n being data driven. From what I've seen working on platforms like Switch, automation is a data driven process. Data is what drives the workflow, even if that data is coming from a file. Again, all we're missing is a good breath of tools that manipulate the files.
Again... good input!
