QTap DevTools – Chrome-style encrypted traffic inspector for Linux
Hi HN, I'm Tyler Flint. Eight months ago we shared qtap here (https://news.ycombinator.com/item?id=43928118). Today we're releasing DevTools - a browser-based interface that gives you the Chrome Network tab experience for server-side HTTP/S traffic. The problem: You're debugging a production issue. An external dependency is returning errors. Your logs say "request failed" but not what was actually sent. Adding debug logging means redeploying and restarting services - which takes time and often changes the conditions you're trying to debug. tcpdump shows encrypted blobs.…

In plain words
QTap DevTools is a browser-based interface for Linux that displays server-side HTTP and HTTPS traffic in a Chrome Network tab-style interface. It helps developers debug production issues by showing live encrypted traffic in plaintext without requiring code changes, service restarts, or certificate configuration. The tool installs quickly and runs locally at localhost:10001, making it useful for engineers troubleshooting external dependency failures and investigating request and response details that logs don't capture.

From the sources
Browser-based interface for server-side HTTP/S traffic debugging. See exactly what your applications send and receive in production, without code changes or proxies.
Traditional debugging tools stop working the moment HTTPS encryption enters the picture, leaving you guessing what went wrong when APIs fail in production. QTap DevTools gives you a local browser-based view of all HTTP/S traffic on a single host. Perfect for emergency troubleshooting when you need to debug a specific server right now. A lightweight, Linux-native sensor running in a guaranteed safe eBPF sandbox, taps into network traffic before and after encryption occurs. The raw data is then re-assembled into protocol-level events and forwarded to a browser-based interface. The closest equivalent to Chrome DevTools' Network tab.

Using eBPF to see through encryption without a proxy2025 · github.com · ▲259Hi HN, I'm Tyler Flint, one of the creators of qtap. For a while now, my team and I at Qpoint.io have been grappling with the challenge of understanding what's actually happening inside the encrypted traffic leaving our production systems. Modern apps rely heavily on third-party APIs (think payment processors, data providers, etc.), but once TLS kicks in, figuring out exactly what data is being sent, identifying PII exposure, or debugging integration issues becomes incredibly difficult without resorting to complex and often brittle solutions. Traditional approaches like forward proxies…

Talanoa▲345Hi 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…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
