duckdb-extensions

What it is and what it does

duckdb-extensions wraps DuckDB's core extension ecosystem into pip-installable packages, so you can add cloud storage, format readers, and database connectors directly from Python without managing external binaries. It packages only DuckDB Labs–maintained extensions, not community or nightly builds, to keep the supply chain trust model clear.

The package bundles pre-built extension binaries for linux_amd64, linux_arm64, osx_arm64, osx_amd64, and windows_amd64, verifying them against SHA-256 checksums before publishing. You install the main package, then load extensions into your DuckDB session with a single import call. Releases track DuckDB's version; the current 1.5.5 is compatible with duckdb==1.5.5.

Use it for:

• Query Parquet, Excel, or Avro files directly in DuckDB without writing custom loaders.
• Connect to PostgreSQL, MySQL, or SQLite databases as DuckDB tables for cross-database joins.
• Read data from S3, Azure Blob Storage, or HTTP endpoints using cloud storage extensions.
• Load Delta Lake or Iceberg tables for analytics on cloud data warehouses.
• Add full-text search or spatial query support to DuckDB via specialized extensions.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Packages DuckDB core extensions as pip-installable Python modules, letting you add functionality like cloud storage, format support, and database connectors to DuckDB without leaving the Python ecosystem.

Yes. Low install friction, active maintenance, no known vulnerabilities, and a permissive MIT license. Install it if you use DuckDB and need any of its core extensions—the pip integration eliminates the friction of managing extension binaries separately. The checksum verification and deliberate scope reduce supply-chain risk.

Install

duckdb-extensions on PyPI

pip install duckdb-extensions

uv add duckdb-extensions

poetry add duckdb-extensions

Installing duckdb-extensions

Before you install

Low friction: pure Python wheel with only duckdb and importlib-resources as runtime dependencies. Active maintenance with a release 4 days old and commits current as of 2026-08-10.

License in practice

MIT license on the wrapper code; bundled extension binaries may carry different upstream licenses. See THIRD_PARTY_LICENSES.md for per-extension terms.

Quickstart

pip install duckdb-extensions

from duckdb_extensions import import_extension
import_extension("httpfs")

import duckdb
print(duckdb.sql("SELECT installed FROM duckdb_extensions() WHERE extension_name='httpfs'").fetchone()[0])

Requires Python >=3.10; duckdb must be installed separately.

Verify before relying

• Whether individual extensions are published as separate packages or bundled in duckdb-extensions itself.
• Whether extension binaries are pre-built or compiled on install for your platform.
• Performance or compatibility differences between PyPI-packaged extensions and DuckDB's native extension loading.
