You seem to be on a bit of a streak finding great Steem related products which nobody has hunted yet, nice work!

The product itself is low cost and can be used on be paid for by the day or monthly which is perfect for people who don't want to be fixed into a contract (common SaaS method).

This application is being used to power some of the features on SteemPlus along with a wide variety of different analyst who is pulling data about Steem daily, the benefit of this, this product is already being used by the community and is already providing benefit to a wide range of people.

The barrier to entry is that you need to know SQL and if you wish to use this in your application you would need to wrap it in an API to not expose your credentials, but overall that's pretty simple and it can be used for a wide selection of different use cases.

Overall nice hunt, and keep up the good work :)
