This release is a pre-release and may not be stable for production use.
Haybarn — Python client
The Python client for Haybarn, an independent derived distribution of DuckDB, powered by DuckDB.
Published by Query Farm LLC.
Haybarn is not affiliated with, sponsored by, or endorsed by the DuckDB Foundation or DuckDB Labs. DuckDB is a trademark of the DuckDB Foundation. See NOTICE.
This package is a fork of the DuckDB Python client, rebranded as haybarn. The
public API is identical to DuckDB's.
Installation
pip install haybarn
Usage
import haybarn
haybarn.sql("SELECT 42").show()
Migrating from DuckDB
Because the API is identical, existing DuckDB code needs only a one-line change:
import haybarn as duckdb # the rest of your code is unchanged
For third-party code you cannot edit, there is an opt-in compatibility shim
that makes import duckdb resolve to Haybarn:
import haybarn.compat # registers haybarn as the `duckdb` module
import duckdb # now this is Haybarn
The compiled extension module is renamed (_haybarn), so a haybarn wheel and
a genuine duckdb wheel can be installed side by side without conflict.
Building from source
See CONTRIBUTING.md and AGENTS.md for the build workflow. In short:
uv sync --only-group build --no-install-project
uv sync --no-build-isolation -v --reinstall
The DuckDB engine is built from the external/duckdb submodule.
License
MIT — the same license as DuckDB. The upstream license is preserved in LICENSE; see NOTICE for the list of Haybarn modifications and trademark attribution.
