OpenTrace

OpenTrace is a free, open-source network diagnostic application designed to visualize the routes that data packets travel across the internet. Built around the NextTrace engine, it provides a graphical alternative to traditional traceroute utilities. Users can examine network hops, identify routing problems, and investigate connectivity between devices and remote servers. The application supports MTR functionality for monitoring network paths and analyzing connection behavior. It also offers custom DNS resolvers, including DNS-over-HTTPS, and local MMDB database support. OpenTrace includes command-line tracing options and multilingual interface localization. Available for Windows, macOS, and Linux, it simplifies network troubleshooting through accessible controls and visual route analysis.
