I am standing at the same step as you. It is confusing what is Flynn. Maybe it is CLU (Codified Likeness Utility) created by Kevin Flynn of TRON.

Flynn.io needs to fight for the user experience... no docs = poor UX

I think in this case it's no docs = no UX

I've given it a test but all it's done is cost me a couple of micropennies on aws so far, I'm nowhere closer to understanding

Same here. How it is possible nowadays to have fronpage that is impossible to understand what your flagship product do.

I know what it is only from being around since it's inception. If I was new to it, I'd probably be confused too.

I've been around since its inception and I've no idea what it does.

It could do with the "explain like I'm 5" version - can I put wordpress on it and have it auto scale over my servers? Is that even a valid use case for this, does Flynn even do that sort of thing?

Like I say I've realised I actually have no idea what Flynn does
