Subtrace – Wireshark for Docker Containers
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…

In plain words
Subtrace is a debugging tool that captures all incoming and outgoing requests in Docker containers, similar to Wireshark for network analysis. It displays complete request details including payloads, headers, status codes, and latency through a Chrome DevTools-like interface. Designed for backend developers, it addresses gaps left by monitoring tools like Sentry and OpenTelemetry by providing full visibility into actual requests without requiring excessive logging that slows systems down.

A toy version of Wireshark (student project)2025 · github.com · ▲265Hi 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…
Trayce – Network tab for Docker containers2024 · trayce.dev · ▲138Trayce (https://github.com/evanrolfe/trayce_gui) is an open source desktop application which monitors HTTP(S) traffic to Docker containers on your machine. It uses EBPF to achieve zero-configuration sniffing of TLS-encrypted traffic. As a backend developer I wanted something which was similar to Wireshark or the Chrome network tab, but which intercepted requests & responses to my containers for debugging in a local dev environment. Wireshark is a great tool but it seems more geared towards lower level networking tasks. When I'm developing APIs or microservices I dont care…

Talanoa▲343Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

I was at FB/Meta from late 2013 to early 2023, mostly working in the compiler/runtime spaces. I got hit in the spring 2023 layoff wave. I immediately started making games in my newfound free time (a lifelong interest, and I even worked in AA(A?) back ca. ~2000), and in October 2023 I stumbled upon the idea of a roguelike pachinko/plinko game inspired by Luck Be A Landlord. Things snowballed quickly, I started talking to publishers, then worked like crazy through all of 2024, almost the hardest I've ever worked in my career, and launched the game in December 2024. It's sold…

i wanted to change the habit of reaching for my phone in the morning and doomscrolling away an hour so i built an app to help me. now i have to literally touch grass before accessing my most distracting apps the app is built in swiftui, uses the screen time apis provided by apple and google vision to recognise grass or not i'd love to get your thoughts on the concept.
