Practical experience of using Structurizr?

Does anyone have any practical experience of using Structurizr for a real system? If so do you still use it or have you switched to something else? What pain points did you experience with it?

We're a small team who develop several microservices. We're after a better diagramming tool than diagrams.net because the number of elements we have in our diagrams is getting to be a pain to manage. Things might be easier if we used a text-as-diagram tool like Structurizr.

Two things worry me about it. Firstly we'd want everything in a single workspace so we can define various views over the system. Would the size of the workspace file become unmanageable after a while? I can't see anyway to combine files into a single workspace.

Secondly I want to generate and maintain parts of the model automatically. For example we have lots of AWS Lambdas so I'd like to write a bit of code to pull the names of all the lambdas from our system and add them to the workspace. I can't find an api to read a DSL local file into a program so it can be manipulated.

Let me know any thoughts or experiences you have with Structurizr (or any similar tool for that matter)
