A CLOSER LOOK
From a busy core to the process behind it. One clear place to explore your machine.
Expand process families, follow their combined CPU and RAM, and keep matching children in context as you search.
Process trees, search, filters & pinningSee utilization, memory and the diagnostics your graphics driver exposes. Choose an adapter and go deeper.
Apple silicon, AMD & NVIDIA · driver dependentYour essential readings and busiest processes, a click away in the menu bar. Jump straight from a process to its inspector.
One sample, pause state & theme across windowsType :3000 or port:443 to find a local TCP listener or bound UDP socket. Socket scans run only when you ask.
Keep bare numbers for process IDsCPU cores, memory breakdowns, graphics adapters, mounted volumes and network interfaces. Inspect the reading behind the number.
Six resource views, with useful detailsNative process icons, clear controls, saved preferences and a refresh pace you choose. The ghost fills in when an icon is unavailable.

Explore individual cores, inspect a short history and follow the readings that matter.
Charts keep roughly two minutes in memory. Gaps show paused or missing readings. GPU diagnostics depend on your driver.
Catppuccin, front and center. Light, dark, colorful and retro when you want a change. The themes you love, with consistent controls and a searchable gallery.

GOOD TO KNOW
Official v1.3.0 builds send a basic app-open count and version without a persistent identifier. Optional feature usage is off by default in Settings → Privacy. Process and system readings stay local. See the Privacy link for details; website analytics is separate.
NeoHtop is free, MIT-licensed and open source. Local desktop monitoring requires no account or cloud subscription. Pro is postponed and is not available to buy or install.
GPU support depends on your operating system and driver. NeoHtop reads macOS IORegistry, AMD sysfs and NVIDIA NVML, with DXGI/DRM inventory for other adapters. Missing counters stay unavailable. Per-process GPU engine accounting is limited to supported Linux DRM drivers.
Yes. The original themes remain, including Catppuccin, Dracula, Nord, Tokyo Night, light palettes, retro choices and High Contrast. Glassy needs supported native effects on macOS or Windows.
It shows CPU, RAM, GPU, network, free storage and the five busiest processes. It shares samples, pause and themes with the main window, and stops polling while hidden. Tray behavior varies by Linux desktop.
Version 1.3.0 includes expandable families with combined CPU/RAM and explicit :3000 or port:443 searches. Family RAM may double-count shared pages, and socket visibility depends on OS permissions. Older releases can differ.
Desktop is the Rust/Tauri/Svelte graphical app. NeoHtop CLI is a separate Go/Charm terminal application. Both are local, open-source monitors with independent feature sets and releases.
NeoHtop Pro is postponed. This release is the free local desktop app.
