One of the issues with LLMs is that each function needs to be tested and observed more thoroughly than regular functions, which leads to these UIs to figure out what the heck is actually going on.

For our DSL (BAML https://github.com/BoundaryML/baml ) we found that adding a VSCode playground to visualize LLM function inputs and outputs was a massive win in terms of debuggability and testability, so I can see why langraph is going this way.
