Debugly

What it does

Just Paste your stack trace → clean, readable output in seconds. Supports Java stack traces, Python Traceback (most recent call last), and more. No signup required. Long stack trace & traceback are very hard to read. Debugly fixes this by beautifying and highlighting main & root cause. This helps to instantly identify cause and effect of an error

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

  Hey!

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…

I developed it because I needed a tool that could help me trace the HTTP requests sent by my tests back to the corresponding methods in our API client. The goal of this tool is to simplify the debugging process, so I designed it to be as simple as possible. It requires no external dependencies, no setup, no superuser privileges, and no code modifications. I'm sharing it with you today because I use it regularly, and it seems like others have found it useful too—so it might be…

So, I created TidyTrace.com to quickly and easily do it for my team members. For example, take this Java stack trace Exception in thread "main" java.util.InputMismatchException\n\tat java.base/java.util.Scanner.throwFor(Scanner.java:939)\n\tat java.base/java.util.Scanner.next(Scanner.java:1594)\n\tat…
