I'll ask another of the "how is this different" questions - how is this different from https://evidence.dev/ ? Quary seems a little like dbt + Evidence from what I can see.
We're big fans of the Evidence team. While there's some overlap, we have a heavier focus on data modelling (similar to dbt). The key difference is we've rebuilt the modelling layer in Rust, leveraging WASM for better performance and browser-based execution. This lets us build a more seamless, end-to-end workflow encompassing transformation + viz optimised for the web.
