Installation

WinGet (Recommended)

winget install marlocarlo.pstop

Chocolatey

choco install pstop

Cargo (crates.io)

cargo install pstop

Don't have Rust/Cargo? Install it in seconds: https://rustup.rs

From GitHub Releases

Download the latest .zip from GitHub Releases, extract, and add to your PATH.

From Source

cargo install --git https://github.com/psmux/pstop

Build Locally

git clone https://github.com/psmux/pstop.git
cd pstop
cargo build --release
# Binary at: target/release/pstop.exe + target/release/htop.exe

All methods install both pstop and htop commands. Yes, you can just type htop on Windows.

Features

🖥️ Per-Core CPU Monitoring

Real-time CPU usage bars for every logical core, color-coded by usage type (user / system / virtual), exactly like htop. CPU columns auto-adjust based on core count (2/4/8/16 columns) and terminal size — just like htop's calcColumnWidthCount.

📊 Memory, Swap, Network & GPU Bars

• Mem bar: shows used (green), buffers (blue), cached (yellow)
• Swap bar: swap usage with color threshold
• Net bar: live RX/TX throughput in the header
• GPU bar: overall GPU utilization percentage (shown on GPU tab, or on any tab when added via F2)
• VMem bar: dedicated video memory usage (shown on GPU tab, or on any tab when added via F2)

🌳 Tree View

Press F5 or t to toggle process tree view — see parent-child relationships with ├─ / └─ tree connectors, collapsible nodes with +/-.

🔍 Search & Filter

• F3 - Incremental search: jumps to matching process
• F4 - Filter: hides all non-matching processes in real-time

📋 Five Tab Views

• Main - Full process table (PID, USER, CPU%, MEM%, TIME+, Command...)
• I/O - Disk read/write rates per process
• Net - Per-process network bandwidth (live download/upload rates with auto-scaling B/s, KB/s, MB/s, GB/s) plus active connection counts. No admin required.
• GPU - Per-process GPU engine utilization and dedicated/shared video memory usage via PDH performance counters
• WSL - Linux processes inside every running WSL/WSL2 distribution: distro, PID, user, state, CPU%, MEM%, RES, threads, TIME+ and full command line. Sampled on a background thread by reading /proc inside the distro (works with Ubuntu, Debian, Fedora, Alpine, Docker Desktop, ...). F9 sends the chosen Linux signal to the selected process.

⚙️ F2 Setup Menu (Full htop Parity)

Press F2 to open the setup menu with 4 categories:

• Meters - Configure header layout (CPU, Memory, Swap, Network, Tasks, Load, Uptime)
• Display Options - 16 toggleable settings (tree view, highlight basename, shadow other users, show threads, detailed CPU time, vim keys, Irix mode, and more)
• Colors - Choose from 23 built-in color schemes with live preview
• Columns - Add/remove/reorder visible columns

⌨️ Keyboard Shortcuts

Familiar htop keybindings — zero learning curve if you know htop.

💾 Persistent Configuration

All settings auto-save to %APPDATA%/pstop/pstoprc and restore on next launch. Your color scheme, display options, column choices, sort preference... everything persists.

⚡ Performance

• ~1 MB single binary (release build with LTO + strip)
• 50ms event polling for instant keyboard response
• Configurable refresh rate (200ms–10s)
• Native Win32 API calls for I/O counters, process priority, CPU affinity
• Zero runtime dependencies

Keybindings

Key	Action
F1 / ?	Help screen
F2	Setup menu (meters, display, colors, columns)
F3 / /	Search processes
F4 / \	Filter processes
F5 / t	Toggle tree view
F6 / >	Sort by column
F7 / F8	Decrease / Increase process priority (nice)
F9 / k	Kill process
F10 / q	Quit
Tab	Switch between Main / I/O / Net / GPU / WSL views
Space	Tag process
c	Tag process and children
U	Untag all
u	Filter by user
p	Toggle full command path / process name
H	Toggle show threads
K	Toggle hide kernel threads
+ / -	Expand / collapse tree node
e	Show process environment
l	List open handles (lsof equivalent)
a	Set CPU affinity (arrow keys/hjkl move, Space toggles, a all, i invert, mouse click toggles)
I	Invert sort order
Arrow keys	Navigate
PgUp / PgDn	Page through process list
Home / End	Jump to first / last process

Vim Mode (opt-in)

Enable via F2 > Display Options > Vim-style keys, or set vim_keys=1 in your config file. Off by default.

Process CPU% above 100

Like htop, the CPU% column counts one fully busy core as 100%, so a busy multi-threaded program (a VM, a compiler) can show 300% or more. The ceiling is 100% times the number of logical CPUs. If you prefer Task Manager style, where the whole machine is 100%, turn off F2 > Display Options > Irix mode, or set irix_mode=0 in your config file.

Key	Vim Mode Action	Replaces
j	Move down	(new — default mode has no bare j)
k	Move up	k = kill in default mode
g	Jump to first process	Home
G	Jump to last process	End
Ctrl+d	Half page down	(new)
Ctrl+u	Half page up	(new)
x	Kill process	k / F9
/	Search	(unchanged, works in both modes)
?	Help	(unchanged, works in both modes)

What changes in vim mode:

• k becomes move up instead of kill — use x or F9 to kill
• h no longer opens help — use ? or F1 instead
• j/k work as bare keys (no Alt modifier needed)
• All other keys (F1–F10, Space, u, t, e, l, a, etc.) remain unchanged

What stays the same:

• Arrow keys, PgUp/PgDn, Home/End still work
• All F-key shortcuts (F1–F10) still work
• / for search, \ for filter
• q to quit, Ctrl+C to quit
• All sorting keys (P, M, T, N, I, <, >)
• Tree view (t/F5), tags (Space/c/U), user filter (u)

Color Schemes

All 23 schemes affect every UI element: header bars, process table, footer, tabs, popups. Each scheme provides a cohesive color palette optimized for readability and visual hierarchy.

The original 7 htop schemes remain the core collection, with 16 Windows Terminal schemes added for users who want consistency across terminal applications.

Quick Reference:

• Need dark mode? Try Default, Dark+, One Half Dark, or Solarized Dark
• Need light mode? Try Light Terminal, One Half Light, Solarized Light, or VSCode Light Modern
• Retro vibes? Try CGA, IBM 5153, Campbell, or Vintage
• High contrast? Try Dark Vivid, Monochrome, or VSCode Dark Modern

Change schemes live: F2 > Colors > select > Enter. Preview updates in real-time.
