Hello, DuckDB DevRel here. Quack is independent from MotherDuck. MotherDuck has its own proprietary protocol, which has been around for years and it supports things like dual execution – see more here:

Of course, in the future MotherDuck can also support Quack, but this is not the only interesting use case for Quack.
