What is this all about?

In August 2021, we held an internal hackathon where we decided to develop a set of graph streaming applications. The main problem we encountered was that developers were wasting a lot of time trying to find the right accessible real-time data sources and learning how to connect to them. This gave rise to the idea of consolidating this data in one place and sharing it with other developers.

Here is the list so far 👇
