CodeTracer – A time-traveling debugger implemented in Nim and Rust
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…
CodeTracer – A time-traveling debugger implemented in Nim and Rust launched on March 6, 2025 with 334 votes, #98 of 7,215 launches that month and more than 99% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
CodeTracer is a time-traveling debugger that records program execution into shareable trace files for multiple programming languages. Users can load trace files in a GUI to navigate forward and backward through execution history and examine memory locations at any point. Currently supporting Noir with community-driven projects underway for Ruby and Python, CodeTracer is built in Nim and Rust with an open trace format designed for extensibility.

FireDBG – A Time Travel Visual Debugger for Rust2023 · firedbg.sea-ql.org · ▲44Hey HN, the is Chris, creator of FireDBG. We’ve been working on this debugger just about a year now. Time travel debugging isn’t a new concept, the new idea here is to use call tree visualisation to help us navigate the debug trace. It supports various Linux distros on x64 and macOS on x64 and M1. It’s only available for Rust right now, but we do want to bring this debugging experience to other programming languages. Please give it a try! Would love to know your thoughts. What’s your anecdote in debugging programs? My stupidity is usually in the form of: after a few hours of debugging, I…

Talanoa▲340Hi 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…
