Overview
NextTrace Web is a spin-off of the NextTrace project. It provides a simple web frontend and API server so you can run traceroutes and visualize results — including hop, IP, ASN, geolocation, domain, packet loss, and latency stats — entirely from your browser.
Reverse proxy note: This project uses WebSocket as its communication protocol. If you configure a reverse proxy, please refer to the Nginx config included in this repository. The provided Docker image already has Nginx reverse proxy built in.
Inspired by PING.PE — thanks for years of keeping that service alive and giving the community such a great reference.
