About this tool
A modern page can make dozens of requests to dozens of hosts; most of them are invisible to the person visiting it. This tool loads the URL in a real browser through the APIVoid HTTP Tracker API and returns the complete list of requests with status, content type, size, server IP and timing, the list of contacted hosts and IPs, and statistics by file type and status class.
Security analysts use it to profile landing pages safely, performance engineers to count bytes and hosts, and privacy-minded site owners to discover which third parties their own pages talk to.

Key features of this tool
External lookups
The lookup runs from our infrastructure, so you see what the public internet sees without exposing your own IP address or network.
Fast and cached
Results come back in seconds; identical lookups are cached for a few minutes to keep the service fast and responsive for everyone.
Easy to reuse
Every result block can be copied with one click or downloaded as a text file, and tables can also be saved as CSV for your reports.
Frequently asked questions
What is this useful for?
Finding third-party trackers and ad networks, measuring page weight, spotting mixed content (http requests on an https page), and investigating what a suspicious page loads without opening it yourself.
Why is the number of requests different from my browser's DevTools?
Ad blockers, cookies, viewport size and timing change what a page loads. The tracker uses a clean browser with ads disabled, so numbers are usually lower than a real visit with cookies.
Is JavaScript executed?
Yes, the page runs in a real headless browser, so requests started by scripts are included.
