An open-source command-line tool that captures what happens when a Java program loads its classes at startup, and turns that into an interactive graph you can explore in a browser.
Best alternatives to witr in 2026
When something's misbehaving on a server — a mystery process eating CPU, a port that shouldn't be open, a file that won't unlock — the usual fix is stitching together output from several different tools like `ps`, `lsof` and `netstat` by hand to figure out what actually started it. witr is a single command-line and terminal-UI tool built to answer that one question directly: given a process, port, container or file, it traces the exact chain of what launched it, so you don't have to reconstruct the story yourself. witr supports tracing by PID or process name, port monitoring, container inspection and file-lock/path analysis, all through an interactive terminal UI with four tabs (processes, ports, containers, file locks), or as scriptable JSON, tree-view or narrative-style output. It has mouse support in the terminal UI and runs cross-platform on Linux, macOS, Windows and FreeBSD. Written in Go, it's free and open source with 21.7k GitHub stars, 756 forks and 588 commits on main, and is installable through 15+ package managers — a sign of real production adoption rather than a weekend project.
