About this tool
There is no server behind Website Traffic Checker. Paste the headers, curl -i output or HAR you captured and Website Traffic Checker maps the hops and status codes locally.
Because browsers block cross-origin live requests, Website Traffic Checker works from captured headers rather than fetching the URL itself. It behaves the same on desktop and mobile, with nothing stored remotely.
Frequently asked questions
What does Website Traffic Checker do?
Use Website Traffic Checker to check your input without installing anything; everything happens client-side.
Is Website Traffic Checker free to use?
Yes — Website Traffic Checker is completely free, with no usage limits.
Where is my data processed by Website Traffic Checker?
Entirely in your browser — Website Traffic Checker keeps your data on your own machine and sends nothing anywhere.
Why can't Website Traffic Checker fetch a live URL itself?
Browsers block cross-origin requests (CORS), so Website Traffic Checker analyzes response headers, curl -i output or a HAR you capture and paste — all locally.
Can I use Website Traffic Checker without a connection?
Yes — after the first load Website Traffic Checker runs entirely offline.
