PacketProbe

What it does

Free browser-based network diagnostics. Test packet loss, latency, and jitter with real-time visualization. Scan your ports for security risks. Check your IP and connection details. No signups, no downloads, no API limits, just open packetprobe.com and go. Built on Cloudflare Workers for speed, privacy, and global coverage. Made for gamers, developers, and anyone tired of "have you tried restarting your router?"

Test your internet connection for packet loss, latency, and jitter using real UDP-like WebRTC measurements. Free, instant, no install. Presets for gaming, VoIP, video calls, and streaming.

Speed tests measure bandwidth over TCP, which silently retransmits dropped packets and hides the problem. PacketProbe measures what actually breaks games and calls: packet loss, jitter, and latency, over real UDP. Numbers only mean something next to a target. See what Valorant, CS2, Warzone, Teams, Zoom or Meet actually need, and whether yours clear it. Your browser establishes a WebRTC data channel to one of our test servers. It then sends numbered packets at a configurable rate and size. The server records which packets arrive (measuring upload loss) and echoes them back (measuring download loss and round-trip latency). Jitter is calculated from the variation in successive round-trip…from packetprobe.com

  A toy version of Wireshark (student project)2025 · github.com · ▲265

  Hi everyone, I recently published a small open-source project. It’s a minimal network packet analyzer written in Go — designed more like a learning toy than a replacement for Wireshark. It currently supports parsing basic protocols like TLS, DNS, and HTTP, and includes a tiny fuzzing engine to test payload responses. You can inspect raw packet content directly from the terminal. The output is colored for readability, and the code structure is kept simple and clear. The entire program is very small — just about 400 lines of Go code. I know it’s not anywhere near Wireshark’s level, and I still…

  Sping – An HTTP/TCP latency tool that's easy on the eye2025 · dseltzer.gitlab.io · ▲178

  I've frequently found myself using [nvitop](https://github.com/XuehaiPan/nvitop) to diagnose GPU/CPU contention issues. The two best things about it are: - It's easy to install if I can access pip in the container - It makes a compelling screenshot (which helps me communicate with coworkers.) With those two lessons in mind: Here is Sping! Purpose: Help observe and diagnose latency issues at layer 4+ (TCP/HTTP/HTTPS) Two good things about it: - It's easy to install if you have pip.

  An ultra-light-weight tool to quickly test your ping2022 · ping.projects.chrisjeakle.com · ▲96

  Howdy HN! I find myself testing my ping from time to time, especially when my internet seems wonky while WFH. It feels like there should be an easier way test my ping than puling up a terminal or a complex web app - especially when I'm on my phone or any other device that doesn't have a terminal. I figured I should be the change I wish to see in the world and created this super light ping test. I also created a latency monitoring solution (https://github.com/cjjeakle/network-monitor), feel free to clone and try it out! I know there are a lot more mature monitoring…
