WhatA multiplayer, columnar spreadsheet application that uses DuckDB on the backend, letting non-technical users explore and manipulate large datasets with a familiar Excel-like interface.
SignalAt least one developer is already building an Excel-like columnar app on DuckDB and had to hack together their own client layer — the demand for spreadsheet-familiar interfaces over analytical databases is real and underserved.
Why NowQuack eliminates the need for custom HTTP plumbing between a spreadsheet frontend and DuckDB backend, and WASM support means the same engine can run in-browser for small datasets and connect to a server for large ones.
MarketData analysts and business users at companies with 50-5000 employees who outgrow Excel but find SQL tools intimidating; $2-5B TAM adjacent to the BI/spreadsheet market; competes with Rows.com, Equals, but none are built on a real columnar engine.
MoatDuckDB's analytical query performance on columnar data creates a genuinely better product experience than competitors wrapping Postgres or APIs — users feel the speed difference immediately.
