What it is

fkill is a cross-platform command-line tool to kill processes by name or ID. It simplifies the task of managing running applications and services, making it an essential utility for developers working on multiple platforms.

fkill stands out as a simple, cross-platform solution for managing processes from the command line, making it an essential tool for developers working in diverse environments without needing to learn platform-specific commands.

When it fits — and when it doesn’t

A good fit for

  • Developers working on cross-platform projects who need a consistent way to manage processes.

  • Teams using CI/CD pipelines that require automated process cleanup.

  • Individual developers who frequently work with multiple applications and need quick access to kill processes.

Look elsewhere if

  • Users requiring advanced process management features beyond killing processes by name or ID.

  • Scenarios where a graphical user interface is preferred over command-line tools.

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited functionality compared to native OS tools

    fkill only allows killing processes by name or ID, lacking advanced filtering options available in native task managers.

  2. 02

    Small community and limited support

    The project has a relatively small number of contributors and issues on GitHub often go unanswered.

  3. 03

    Performance limitations for large process lists

    Interactive mode can become sluggish when dealing with a very large number of processes, impacting user experience.

What it does well

  • Cross-platform support for Windows, macOS, and Linux.

  • Kill processes by name or ID.

  • Interactive mode to select processes from a list.

  • Supports command-line arguments for automation.
