fdl — Frozen DuckLake CLI

fdl automates the lifecycle of Frozen DuckLake catalogs — from initialization to deployment.

Installation

See Installation for other methods (uv, pipx).

Features

• Publish data to S3-compatible storage or local directories with a single command
• Run data pipelines with automatic storage and credential resolution
• Serve datasets over HTTP for instant DuckDB access
• Works with dbt and dlt out of the box
• CLI and Python API share the same operations, so pipelines (e.g. Dagster) can drive fdl in-process
