A LinkedIn post from MotherDuck highlights the introduction of “Quack,” a new HTTP-based client-server protocol for DuckDB that aims to enable multiple clients to connect to a single DuckDB server. The post notes that this approach is intended to avoid file-lock conflicts and data transcoding, formalizing patterns that users have reportedly been improvising for years.

According to the post, MotherDuck has been operating DuckDB in both client and server roles for nearly four years and is actively testing Quack. The company indicates it plans to support Quack as a MotherDuck endpoint, targeting compatibility with DuckDB 2.0, positioning itself as an early adopter within the DuckDB ecosystem.
The linked write-up by MotherDuck’s Jordan Tigani is described as outlining how Quack could enable multi-user permissions, SSO, separation of storage and compute, differential storage, “hypertenancy,” read scaling, and serverless lifecycle management. These themes suggest MotherDuck is aligning its roadmap with cloud-native, multi-tenant analytics patterns that may appeal to enterprise and developer customers.
For investors, the post implies that MotherDuck is seeking to deepen its strategic integration with DuckDB and capture workloads that benefit from centralized server deployments rather than purely embedded usage. If adoption of Quack and DuckDB 2.0 accelerates in data engineering and analytics communities, MotherDuck’s early support and experience could strengthen its competitive position and expand its addressable market.
