Nice, is this comparable to Hasura? What are some differences if so?

Yeah it is comparable:

- We are 100% open source. - Written in Typescript. - We support any data source directly in the server process, either with pre-built data providers or build your own. - We support cross data source filtering (get orders from database with CRM username)
