genact - a nonsense activity generator

CI Docker Hub license Stars Downloads

Pretend to be busy or waiting for your computer when you should actually be doing real work! Impress people with your insane multitasking skills. Just open a few instances of genact and watch the show. genact has multiple scenes that pretend to be doing something exciting or useful when in reality nothing is happening at all.


Packaging status

You don't have to install anything! For your convenience, prebuilt binaries for Linux, OSX and Windows are provided here that should run without any dependencies. Additionally, there is a web version at

It's compatible with FreeBSD, Linux, macOS, Windows 10 (it needs a recent Windows 10 to get ANSI support) and most modern web browsers that support WebAssembly.

On FreeBSD: You don't have to do anything special here. Just run

pkg install genact

On Linux: Download genact-linux from the releases page and run

chmod +x genact-linux

On macOS: Download genact-osx from the releases page and run

chmod +x genact-osx

A homebrew package is also available. To install it this way, run

brew install genact

On macOS, you can also install via MacPorts:

sudo port install genact

On Windows: Download genact-win.exe from the releases page and double click it.

It is also available on Scoop:

scoop install genact

With Cargo: If you have a somewhat recent version of Rust and Cargo installed, you can run

cargo install genact


To see a list of all available options, you can run

./genact -h


cargo run -- -h

or (on Docker)

docker run -it --rm svenstaro/genact -h


A nonsense activity generator

Usage: genact [OPTIONS]

  -l, --list-modules
          List available modules
  -m, --modules <MODULES>
          Run only these modules [possible values: download, simcity, ansible, bruteforce, botnet,
          mkinitcpio, weblog, rkhunter, memdump, bootlog, cc, cryptomining, docker_build,
          docker_image_rm, cargo, julia, kernel_compile, composer]
  -s, --speed-factor <SPEED_FACTOR>
          Global speed factor [default: 1]
      --exit-after-time <EXIT_AFTER_TIME>
          Exit after running for this long (format example: 2h10min)
      --exit-after-modules <EXIT_AFTER_MODULES>
          Exit after running this many modules
  -h, --help
          Print help information
  -V, --version
          Print version information

Web usage

In the web version, you can run specific modules by providing them as ?module parameters like this:

You can also provide a ?speed-factor like this:


You should have a recent version of rust and cargo installed.

Then, just clone it like usual and cargo run to get output:

git clone
cd genact
cargo run --release


This is mostly a note for me on how to release this thing:

  • Make sure is up to date.
  • cargo release <version>
  • cargo release --execute <version>
  • Releases will automatically be deployed by GitHub Actions.
  • Update Arch package.
