features

Everything Task Manager should have shipped with.

Six things it does well, in the order you'd actually reach for them.

Grouped, searchable, sortable

Multi-instance apps collapse into one row — expand "Google Chrome (5)" to see every tab process. Filter by name, sort any column.

core

Right-click to end a task

A real context menu on every row and sub-row — no more hunting for the toolbar button.

core

Efficiency mode

Collapse row height when you just need to scan a long process list, not read it.

Live CPU, memory, disk & network charts

A 60-second rolling history per metric, sampled straight from the OS every 1.5 seconds.

performance

One native window, three OSes

Built on Tauri: the UI is a system webview, not a bundled Chromium — no 150 MB install for a process list.

tauri

Rust reads the numbers

sysinfo polls the kernel directly for CPU, memory, disk and network — the frontend only renders what it's told.

rust

terminal ui · otm

The same task manager, in your terminal.

otm is the terminal version: the same seven tabs and the same Rust data as the desktop app, driven by keyboard or mouse. Handy over SSH, on servers, or anywhere you'd reach for htop.

~ $ otm

Install it in a minute.

On Linux, every package installs both: the desktop app (Open Task Manager in your app menu) and otm for the terminal.

Ubuntu, Debian, Linux Mint, Pop!_OS (apt)

Add the signed repository once, then updates arrive with the rest of your system via sudo apt upgrade. Needs Ubuntu 22.04+ or Debian 12+, x86_64.

curl -fsSL https://sabaoongfx.github.io/Open-Task-Manager/KEY.gpg \
  | sudo gpg --dearmor -o /usr/share/keyrings/open-task-manager.gpg
echo "deb [signed-by=/usr/share/keyrings/open-task-manager.gpg] https://sabaoongfx.github.io/Open-Task-Manager stable main" \
  | sudo tee /etc/apt/sources.list.d/open-task-manager.list
sudo apt update && sudo apt install open-task-manager

Arch Linux, Manjaro, EndeavourOS (pacman)

A signed pacman repository, built natively on Arch. Add it once, then sudo pacman -Syu keeps it updated.

curl -fsSL https://sabaoongfx.github.io/Open-Task-Manager/KEY.gpg | sudo pacman-key --add -
sudo pacman-key --lsign-key "Open Task Manager packages"
printf '\n[open-task-manager]\nServer = https://sabaoongfx.github.io/Open-Task-Manager/arch/$arch\n' \
  | sudo tee -a /etc/pacman.conf
sudo pacman -Sy open-task-manager

macOS

Pick your Mac's chip (Apple menu → About This Mac), open the .dmg and drag the app to Applications.

Apple Silicon (M1 and newer) Intel Mac

The app isn't notarized yet, so the first time you open it, right-click it and choose Open.

Fedora, openSUSE and other distributions

All links always give the newest version, x86_64. The .rpm and .deb include otm; the AppImage is the desktop app only.

AppImage (any distro) .rpm (Fedora, openSUSE) .deb

For the AppImage, make it executable and run it:

chmod +x Open-Task-Manager-x86_64.AppImage
./Open-Task-Manager-x86_64.AppImage

For the .rpm: sudo dnf install ./Open-Task-Manager-x86_64.rpm (or zypper install on openSUSE).

Just `otm`, the terminal UI

For servers and minimal installs: no desktop app, no webview. Each download is a single otm binary in an archive, always the newest version.

Linux x86_64 macOS Apple Silicon macOS Intel Windows

On Linux, straight from the terminal:

curl -fsSL https://github.com/sabaoongfx/Open-Task-Manager/releases/latest/download/otm-x86_64-unknown-linux-gnu.tar.gz | tar xz
sudo install otm-*/otm /usr/local/bin/
otm

Or build it with Rust:

cargo install --locked --git https://github.com/sabaoongfx/Open-Task-Manager otm
otm
