About witr
witr is a command-line and terminal user interface tool that helps developers trace running processes, listening ports, containers, and files back to their origins. It answers the question of why something is running by showing the causal chain of events that started it. The tool works across Linux, macOS, Windows, and FreeBSD as a single static binary, making it useful for incident response, troubleshooting, observability, and system administration tasks.
Developed by pranshuparmar, witr is written in Go and released under the Apache 2.0 license. The project includes an interactive playground where users can practice investigating a simulated Linux system and learn the tool's features through guided scenarios. Installation options include package managers like Homebrew, APT, and Winget, as well as direct installation scripts for various platforms.
