About COGext : System Monitor

COGext transforms system data into an elegant, accessible dashboard. It provides a high-level or detailed overview of your environment with a single click. The objective is to be comprehensive and complete while remaining simple and clear. CPU, memory, battery, and network: the essentials are exposed through a streamlined interface that prioritizes utility and ease of use. Disclaimer: some features may not work depending on your OS and permissions. Key Features - 4-Monitor Grid & 9 Data Cards: The interface exposes real-time data for CPU usage, memory, battery status, and network connectivity. Deep-dive cards provide additional information on processor architecture, thermal sensors, display resolutions, and more system information. - NEW zoom mode. - Universal Accessibility: Built to meet WCAG 2.2 AAA standards. The dashboard provides full support for keyboard, touch, and screen readers (including optimized semantic audio for ChromeVox). - Global Support: Available in 23 languages. - Personalized Experience: Select your preferred temperature unit, toggle the zoom or between light/dark modes, and set the interface color from 5 distinct tones. - Efficiency: Engineered for maximum responsiveness with a minimal footprint to ensure your browsing experience remains smooth. Privacy & Security - Permissions We Ask: “Storage” & “Management” are required only to expose your Drives and Chrome extensions. Requests to api.ipify.org (up to 0.03Hz) and clients3.google.com (0.2Hz) are performed only to provide your public IP and network latency. - What We Do With Your Data: Your system data and extension usage are NEITHER recorded NOR transmitted in any way. All session data is cleared as soon as the extension is closed. - Fully Auditable: COGext is Open-Source (GPLv3).
