Still working (and ready to share a link this time) on Satonomics, a free and open-source alternative to Glassnode (Bitcoin on-chain data) which will be in the future self-hostable.

Quit me (first) job to work full-time on this in November and it's been going great ! I'm not sure yet how I'll earn a living but I guess we'll see.

Sadly, I just realized that while I wanted to minimize the network transfers. Height datasets are too slow, there aren't perfectly optimized but still, I'll have to move the datasets logic to the back-end which will take some time. The silver lining is that I'll be able to add a dashboard similar to Clark's much more easily !

@Car - Here's an update since you were interested !
