Ask HN: Looking for turnkey Python application back end

Apologies for using HN as an HN search tool...

I'm trying to find an application that was announced on HN some months ago. It was a complete application development backend in Python. It had user management, auth, etc. all pre-built into a single codebase. You could purchase the code out-right.

I keep trying to find it, and I keep failing.

Does anyone remember what this product was called, or know of something similar?
