## What it is
CodeTracer is a time-traveling debugger that records program execution into a self-contained, shareable trace file. It provides a GUI for stepping forward and backward through execution and tracing the origin of any memory value to find root causes of bugs.

## Use cases
- debug a bug that is hard to reproduce by recording it once and replaying it
- find where a bad value in my program came from
- step backwards through program execution to find the root cause of a crash
- share a recording of a failing program with a teammate for debugging
- trace memory corruption back to the code that wrote it
- debug Rust, C, C++, Ruby, or Noir programs with reverse execution

## When to choose
- you need to debug non-deterministic or hard-to-reproduce bugs
- you want to trace the origin of values across an execution history
- you need to share a failing execution as a self-contained trace file
- you work in Rust, C/C++, Ruby, or Noir and want time-travel debugging

## When to avoid
- you only need simple breakpoint debugging with a standard debugger like GDB or LLDB
- your program's overhead from recording is unacceptable in production
- you need a debugger for an unsupported language
- you work exclusively on platforms outside Linux, macOS, or Windows

## Facets
- artifact type: application
- maturity: active
- function: developer-tools, gui
- domain: developer-tools, testing, programming-languages
- platform: windows, cross-platform
- tags: time-travel-debugger, reverse-debugging, trace-recording, deterministic-debugging, record-replay, debugging, linux, macos
