It abstracts away the complexity of SQL parsing by using pluggable parsers (sqlfluff and sqlparse) and stores lineage information in a graph structure using networkx. The tool works at both table and column levels, identifying which tables are read and written, and tracking individual column transformations across joins, aggregations, and CTEs.\n\nYou can use it as a command-line tool to analyze SQL files or inline queries, or import it as a library in Python code. It supports dialect-aware parsing, can optionally integrate with live database metadata via sqlalchemy to resolve wildcards and ambiguous column references, and includes graph visualization of lineage as a DAG. It handles multiple SQL statements in sequence, identifying intermediate tables that serve as both targets and sources.","worth_installing":"Yes. SQLLineage is actively maintained, has no known vulnerabilities, installs with low friction, and solves a real problem in data governance and pipeline auditing. The MIT license imposes no restrictions. It is suitable for production use in both open-source and commercial contexts."},"id":"sqllineage","links":{"html":"https://skillfed.io/packages/sqllineage","md":"https://skillfed.io/packages/sqllineage.md","pypi":"https://pypi.org/project/sqllineage/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-16","license_spdx":"MIT","license_treatment":"permissive","name":"sqllineage","python_support":"supports_current","summary":"SQL Lineage Analysis Tool powered by Python"},"popularity":{"monthly_downloads":1725919,"position":3611,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.5.8"}
