One pipeline. Write it, wire it, or draw it. Duckle is the open, single-engine ELT stack. One pipeline format, compiled to SQL on DuckDB: write it in Python, wire it from 350+ connectors and components, or draw it on the canvas - or describe it to Duckie, the on-device AI assistant, and verify what it builds. In-pipeline transforms, data quality, and lineage travel with the same artifact. Runs anywhere - laptop, CI, headless, or a browser - and fully offline when you need it. No per-row tax, no lock-in. Duckle is an independent open-source project by SlothFlowLabs. It builds on the DuckDB engine but is not part of, affiliated with, or endorsed by DuckDB Labs or MotherDuck. <img alt="tauri" src="https://img.shields.io/badg
