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.

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. Setting up mitmproxy means certificates, restarts, reconfiguration. Our solution: install qtap, enable DevTools, open localhost:10001 in your browser. You're now watching live HTTP/S traffic - every request, response, header, body - in plaintext. No restarts, no certificates, no code changes. It works by hooking into TLS libraries (OpenSSL, Go crypto, Java SSL, Node.js, etc) via eBPF before encryption happens. Getting started: # Option A: Install script (inspect it first if you prefer) curl -s https://get.qpoint.io/install | less curl -s https://get.qpoint.io/install | sudo sh sudo qtap --enable-dev-tools If you're (rightly) skeptical of curl | sh, grab the binary directly or build from source. We get it. # Option B: Direct binary download (use the link for your architecture) curl -L https://downloads.qpoint.io/qpoint/qtap-latest-linux-amd64.tgz -o qtap.tgz # curl -L https://downloads.qpoint.io/qpoint/qtap-latest-linux-arm64.tgz -o qtap.tgz tar -xzf qtap.tgz sudo ./qtap --enable-dev-tools Then open http://localhost:10001 # For remote servers, use SSH port forwarding or Tailscale/Twingate ssh -L 10001:localhost:10001 user@remote-server Key features: - Process/container attribution (which container made that call?) - Real-time SSE streaming - Copy any request as cURL - Data never leaves your machine DevTools is free and open source (AGPL-3.0). GitHub: https://github.com/qpoint-io/qtap Docs: https://docs.qpoint.io/release-notes/devtools Questions we'd love feedback on: - What debugging scenarios would you use this for? - Any protocols beyond HTTP you'd want? (Postgres, MySQL, Redis coming soon)

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
