The product is now live at https://stakerops.io/
Also, the entire dataset is available as a public data set in BigQuery.
Are there plans to open-source the product at this point?
The constituent pieces are open source: GitHub - wealdtech/chaind and GitHub - getredash/redash: Make Your Company Data Driven. Connect to any data source, easily visualize, dashboard and share your data.. Other than those, it’s mainly a bunch of cloud services and misc glue/scripts.
