Thanks! I agree, was surprised to learn that there aren't that many good open source no-code tools out there.

I couldn't find the source code, where is it on github?

The open source release will probably happen within 3 weeks from now. It is an early test version that is running on baserow.io, but this is for trying it out only. I still need to write documentation, an openapi spec, a plugin boilerplate and some other small things. When that is finished I will make the code available publicly.
