Watching Webpages in Action with Lookyloo

" summary

Lookyloo captures pages in a configured headless browser and builds a phylogenetic resource tree showing time‑ordered requests, hashes every resource, stores HAR/BASE64 blobs, and links assets for download. It runs via headless Chrome via Playwright, visualizes with d3/Flask, finds surprising issues (widespread pre‑consent tracking, phishing kits reusing the same CSS, hidden redirect chains) and integrates VirusTotal/MISP; service‑worker edge cases and long timeouts still need extra handling.
