Show HN: I made a data lineage tool for AI data pipelines

1 badmonster 0 6/24/2025, 6:31:56 PM cocoindex.io ↗

Hi HN, I made a data lineage tool for AI data pipeline, as a companion to open source ETL framework cocoindex.

After months in private beta (and lots of love from early users), we’re excited to officially launch it today.

It offers: - Before/after of the data are available at every transformation node - Every output field can be traced back to the exact set of input fields and operations that created it - Lineage is first-class - Zero pipeline data retention, connecting seamlessly to on-prem CocoIndex server

This tool is free, and you can get start by running

cocoindex server -ci main.py

with any of the cocoindex projects https://github.com/cocoindex-io/cocoindex/tree/main/examples

Thanks! Linghua
