OutTrace

Built a Chrome extension that turns any webpage into a graph of every domain it's secretly talking to.

LinkScope. Click Scan on any page and it opens a full interactive graph of every site, service, tracker, script, and external domain that page connects to — click any node to see why it's there.

Runs entirely local — no server, no accounts, nothing ever leaves your machine. Keeps a history so you can look back at past scans too.
