Products that do what A toy version of Wireshark (student project) does
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…

Hey HN, we built Subtrace (https://subtrace.dev) to let you see all incoming and outgoing requests in your backend server—like Wireshark, but for Docker containers. It comes with a Chrome DevTools-like interface. Check out this video: https://www.youtube.com/watch?v=OsGa6ZwVxdA, and see our docs for examples: https://docs.subtrace.dev. Subtrace lets you see every request with full payload, headers, status code, and latency details. Tools like Sentry and OpenTelemetry often leave out these crucial details, making prod debugging slow and annoying. Most of the…

This code is still in early beta, but i sincerley hope it will become as ubiquitous as VIM on Linux.

Hi all, I'm excited to announce Stratoshark, a sibling application to Wireshark that lets you capture and analyze process activity (system calls) and log messages in the same way that Wireshark lets you capture and analyze network packets. If you would like to try it out you can download installers for Windows and macOS and source code for all platforms at https://stratoshark.org. AMA: I'm the goofball whose name is at the top of the "About" box in both applications, and I'll be happy to answer any questions you might have.

Hey all, I built babyshark, a terminal UI for PCAPs aimed at people who find Wireshark powerful but overwhelming. The goal is “PCAPs for humans”: Overview dashboard answers what’s happening + what to click next Domains view (hostnames first) → select a domain → jump straight to relevant flows (works even when DNS is encrypted/cached by using observed IPs from flows) Weird stuff view surfaces common failure/latency signals (retransmits/out-of-order hints, resets, handshake issues, DNS failures when visible) From there you can drill down: Flows → Packets → Explain (plain-English…

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. (Available at…

Hi HN, Some misbehaving networks drop WireGuard packets either by accident or on purpose. Commonly the latter is done with simple DPI rules that block the handshake initiation [1], but it could be applied to other message types as well. We thought it would be great if there was tool for folks to use as a quick litmus test to see if this happening for them, without having to configure a client to send data through a random, functional WireGuard tunnel to an untrusted remote host. So we built probe.sh. How it works: - The probe.sh web app is an Elixir Phoenix app that spawns a few gen_udp…

We built Gonzo to make log analysis faster and friendlier in the terminal. Think of it like k9s for logs — a TUI that can ingest JSON, text, or OpenTelemetry (OTLP) logs, highlight and boil up patterns, and even run AI models locally or via API to summarize logs. We’re still iterating, so ideas and contributions are welcome!

I'm launching Wirewiki.com today! Wirewiki makes the internet’s hidden infrastructure browsable. I quit my job 5 years ago to scale Nslookup.io. But after reaching 600k monthly users, I hit a ceiling. I couldn't naturally expand beyond DNS because of the domain name. So I went back to the drawing board: how would I make it today? Not as a collection of tools, but as a browsable graph. I've spent hundreds of hours and commits building that. It's not even at 10% of what I want it to be, but more than enough to be useful, and (in my biased opinion) much better than what's out there. Wirewiki…

Hey HN! I just released go-nbd, a lightweight Go library for effortlessly creating NBD servers and clients. Its a neat tool for creating custom Linux block devices with arbitrary backends, such as a file, byte slice or what I'm planning to use it for, a tape drive. While there are a few partially abandoned projects like this out there already, this library tries to be as maintainable as possible by only implementing the most recent handshake revision and baseline functionality for both the client and the server, while still having enough support to be useful. I'd love to get your feedback :)

Hello everyone! I was poking around GoLang's HTTP/networking capabilities to see what things I could do. Turns out it is pretty easy to insert your own networking stack into HTTP clients and servers.

I often reached for `socat` when I needed to forward a TCP port from my local machine for testing, and I was curious how easy it was to write such a utility in Go. At 105 lines of Go, it was easy enough. It has limited functionality - TCP only, no port mapping, binds to all local network interfaces - but it serves its purpose, so I wanted to share this with others.

I have been using golang at work and personally for more than 2 years now. A problem i faced when I started and the problem new gophers even today is how to structure the project. Most (if not all) golang tutorials seem to be very simple and do not describe how to structure a large application. Following project is an attempt to Showcase a manageable project layout for services in golang. https://github.com/spy16/droplets This project is far from complete. Would like to hear some feedback from the community before continuing on this.

Wiregasm lets you build applications that can leverage Wireshark's packet dissection capabilities in a web browser or nodejs. The project is in its infancy, the goal is to make most of sharkd APIs available in Wiregasm. The bindings at the moment are not perfect as I'm still trying to familiarize myself with Emscripten. It is part of a bigger hobby project that my wife and I are working on, to make some of the development and security tools that we use available in a web browser.
