It's the same name I gave an old open source python package I created to parse html meta tags (social, Facebook, twitter etc)... It's on pypi for a long while now.
A really good open source Tableau alternative, maybe the best IMHO. In contrast to for example Apache SuperSet this can actually be used by business people because it supports joins of datasets.
I tried installing it and my options were a bunch of manual steps, a VM, or a 6GB docker file.
They have a cool sandbox that I tried to use and poke around a bit.
Tableau's big selling point, I think, is its approachability and dead simple start. This will need an install that users can do and a "show me" type interface that lets people easily start up.
It looks promising and being OSS is great. I'll look deeper into it, but this isn't an alternative to Tableau, imho.
They are end to end analytics and do also the data processing etl with a simple ui. I’d say at least on paper metatron is a much more complete product.
The piece that's missing here is something like Lyft's Amundsen tool: a discovery portal for the organization to share and search over datasets and knowledge bases.
I personally know some guys there and checked about this. They say that they are currently under development of meta data management(if that's what you we're referring to)
