In simple English
This tool downloads public web link data to find every site pointing to yours. It compares your backlinks with a competitor to find missed opportunities. You do not need a paid subscription or an expensive service. It saves data in a local database so you can search it offline. The first run downloads large files, so you need plenty of disk space and a fast connection.
What it is
A Python script that queries Common Crawl hyperlink graphs using DuckDB and stores results in SQLite. It performs backlink audits and competitor gap analysis locally.
