    QTap DevTools – Chrome-style encrypted traffic inspector for Linux▲30

    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.…

    Duper – The Format That's Super▲31

    An MIT-licensed human-friendly extension of JSON with quality-of-life improvements (comments, trailing commas, unquoted keys), extra types (tuples, bytes, raw strings), and semantic identifiers (think type annotations). Built in Rust, with bindings for Python and WebAssembly, as well as syntax highlighting in VSCode. I made it for those like me who hand-edit JSONs and want a breath of fresh air. It's at a good enough point that I felt like sharing it, but there's still plenty I wanna work on! Namely, I want to add (real) Node support, make a proper LSP with auto-formatting, and get it out…

    I built a tool to un-dumb Claude Code's CLI output (Local Log Viewer)▲69

    Hi HN, I built this because I got tired of the Claude Code CLI hiding details from me. Recent updates have replaced critical output with summaries like "Read 3 files" or "Edited 2 files". To see what actually happened, I was forced to use `--verbose`, which floods the terminal with unreadable JSON and system prompts. I wanted a middle ground: *Full observability without the noise.* `claude-devtools` is a local Electron app that tails the session logs in `~/.claude/` to reconstruct the execution trace in real-time. *Unlike wrappers, it solves the visibility gap in your native…
