Hey! this is Moritz. one of the creators of datablocks. the project is in a very early stage and more like a showcase right now. If you have any feedback, please let me know :) It's very valuable for us. We open sourced the underlying library for creating the flows. It's called react flow https://reactflow.dev/. The backend is built with nhost and we can really recommend it -> https://nhost.io/! Thanks for the nice words here :)
