Code Debugger(Visualze Line-By-Result)

What it does

Stop getting lost in your own logic. CMDbug is a specialized visual debugger built for the DSA journey. While standard debuggers are built for production apps, CMDbug is built for learning. Trace your code’s execution in real-time, visualize complex data structures, and manage your workflow with a unique multi-console interface. Whether you are prepping for a Big Tech interview or learning to code for the first time, CMDbug helps you see the solution, not just write it.

  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). *…

  CodeTracer – A time-traveling debugger implemented in Nim and Rust2025 · github.com · ▲334

  Hey! We are presenting CodeTracer - a user-friendly time-traveling debugger designed to support a wide range of programming languages: https://github.com/metacraft-labs/codetracer?tab=readme-ov-f... CodeTracer records the execution of a program into a sharable self-contained trace file. You can load the produced trace files in a GUI environment that allows you to move forward and backward through the execution and to examine the history of all memory locations. They say a picture is worth a thousand words — well, a video is even better! Watch the demo below to see…

  Dlg – Zero-cost printf-style debugging for Go2025 · github.com · ▲64

  Hey HN, I tend to use printf-style debugging as my primary troubleshooting method and only resort to gdb as a last resort. While I like its ease of use printf debugging isn't without its annoyances, namely removing the print statements once you're done. I used to use trace-level logging from proper logging libraries but adding trace calls in every corner quickly gets out of control and results in an overwhelming amount of output. To scratch my own itch I created dlg - a minimal debugging library that disappears completely from production builds. Its API exposes just a single function, Printf…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
