Übersicht vs Nexus

Übersicht is a free macOS app that places the output of system commands on the desktop in small widgets. Widgets can present information as tables, charts, or graphs, adapt to screen sizes, and are written in HTML5, JavaScript, and React JSX. The app includes a gallery and installation instructions for community widgets, spanning categories such as system monitoring, clocks, calendars, weather, RSS feeds, networking, and media. For development, Übersicht watches the widget directory and updates the display when files change. Commands run at a configurable interval, once per second by default, or can be set not to refresh automatically. A built-in local proxy supports Ajax requests to external sites, and AppleScript scripting is available. The download page specifies macOS 12 or later, and the app is released under the GNU General Public License version 3 or a later version at the user's option. Widgets can execute arbitrary code, so the maker advises checking their source; malicious code cannot be ruled out.

Nexus combines PC hardware monitoring, fan and pump control, and RGB lighting in one free app. It shows live CPU, GPU, memory, network, disk, fan, and temperature readings, with per-game FPS history on Windows. Its GPU-rendered lighting engine offers screen sync, audio sync, and Game Sync. Users can set fan and pump curves from any system temperature sensor or leave selected devices on BIOS or firmware settings. Nexus uses its own device drivers and a bundled OpenRGB build; hardware support depends on the exact model. A phone browser can act as a remote panel, using an encrypted relay outside the home network and switching to a direct connection when possible. The app works locally and offline without an account, while optional anonymous telemetry can be controlled in settings. Nexus runs on 64-bit Windows 10 or 11, Apple Silicon Macs, and x86-64 Linux. It has no builds for Windows on ARM, Intel Macs, or ARM Linux. Companion iOS and Android apps are not yet in the app stores.
