What it does

Stuck in a gigantic for loop, you have to catch bugs before the execution thread(laser) runs into them. The map shows your current position in this nested loop. You will be roughly experiencing debugger's struggle in this simple browser-based game.

  A web debugger an ex-Cloudflare team has been working on for 4 years2024 · ▲886

  Hey HN, I wanted to show you a product a small team and I have been working on for 4 years. https://jam.dev It’s called Jam and it prevents product managers (like I used to be) from being able to create vague and un-reproducible bug tickets (like I used to create). It’s actually really hard as a non-engineer to file useful bug tickets for engineers. Like, sometimes I thought I included a screenshot, but the important information the engineer needed was what was actually right outside the boundary of the screenshot I took. Or I'd write that something "didn't work" but the engineer…

  Letting LLMs Run a Debugger2025 · github.com · ▲147

  Hey HN, I just built an experimental VSCode extension called LLM Debugger. It’s a proof-of-concept that lets a large language model take charge of debugging. Instead of only looking at the static code, the LLM also gets to see the live runtime state—actual variable values, function calls, branch decisions, and more. The idea is to give it enough context to help diagnose issues faster and even generate synthetic data from running programs. Here’s what it does: * Active Debugging: It integrates with Node.js debug sessions to gather runtime info (like variable states and stack traces). *…

  Fatal Core Dump – A debugging murder mystery played with GDBMar 2026 · robopenguins.com · ▲68

  Debugging a crash can sometimes feel like a noir detective story: following faint clues, chasing red herrings, and eventually hitting the moment where the whole case finally makes sense. I leaned into that idea and built Fatal Core Dump, a small game where the investigation is real crash debugging. The game gives you a Linux binary, its core dump, a source file, and some logs. You solve the mystery by debugging it. The premise: an engineer dies when an airlock on an asteroid mining station opens unexpectedly. Your job is to determine whether it was a simple software bug or something more…

  Videobug – The time travel debugger for JVM2022 · ▲63

  Hi All, this is Shardul here - I am the co-founder of Videobug. https://bug.video We are super excited to share Videobug with you. Videobug records run time code execution so that developers can watch it line by line as frequently as they want, right in their IDE. It takes away the pain of recreating exact conditions that led to a bug and saves developer time in every bug squash. Parth (my co-founder) and I have worked on multiple production grade applications in startups and enterprises. We used Logrocket, Sentry, and Datadog for logging and found ourselves adding more logs after…

  Browser debugging tool an ex-Cloudflare team has been building for 4yrs2024 · ▲12

  Hey HN, I wanted to show you a product a small team and I have been working on for 4 years. It’s called Jam (jam.dev) and it prevents product managers (like I used to be) from being able to create completely vague and un-reproducible bug tickets (like I used to create). It’s actually really hard as a non-engineer to file useful bug tickets for engineers. I used to write in the ticket that something didn’t work— only to lead to a ton of confusion by the engineer what I meant by “didn’t work”. Was the button unresponsive? Did the page crash? Did it return an error? Or like sometimes I thought…
