# DuckDB · compute · 2025

Revision 1 (11 October 2026) · Modeled snapshot · through 8 October 2026.

All figures are research-informed estimates of analytical activity. Significant errors may remain; decimal places do not imply measurement precision.

1.65% of the full compute layer.

[DuckDB](https://history.columnar.tech/technologies/compute/duckdb.md): historical names and annual shares.

Includes MotherDuck, available in public beta from 2023 and generally available from June 2024. This share combines local and embedded DuckDB use with the hosted MotherDuck service; MotherDuck is not counted again in another engine box.

Connections below describe the whole DuckDB engine. Access and storage mixes are estimated separately; they are not a joint interface-to-storage distribution.
