About
NeoHtop is a free, open-source system monitor for macOS, Linux, and Windows that requires no account. You can expand process families to see their combined CPU and RAM, search for processes, use filters and pinning, and find which local TCP listener or bound UDP socket is using a port by typing a search like :3000. GPU support depends on your operating system and driver. Where available, it shows utilization, memory, and driver diagnostics, and you can choose an adapter to inspect.
The main window also lets you open cards for CPU cores, memory, graphics adapters, storage volumes, and network interfaces to see more detail and a short history of readings. NeoHtop offers 24 themes, including Catppuccin, Dracula, Nord, Tokyo Night, and High Contrast, and it is built with Rust, Tauri, and Svelte.
A menu-bar companion shows CPU, RAM, GPU, network, free storage, and the five busiest processes, and it shares samples, pause state, and themes with the main window. It stops polling while hidden. Official v1.3.0 builds send a basic app-open count and version without a persistent identifier, and optional feature usage is off by default in Settings.
