Mixed Content Traffic Detector
Detect HTTP resources and insecure redirects in HAR sessions indicating mixed-content or transport downgrade risk. Free by Graph Tools.
Use this free mixed content traffic detector to find insecure HTTP requests within HTTPS sessions captured in a HAR file. The tool flags plain HTTP resource loads, HTTP redirects from HTTPS endpoints, and API calls that bypass TLS — all indicators of transport security risk. Upload a HAR export from browser DevTools and get a grouped list of affected resources. Useful for frontend security reviewers, DevOps engineers, and QA teams testing web applications.
