COGext : System Monitor

Tracking since Apr 17, 2026.

Changelog

• Jun 6, 2026
  description

  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.
  
  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.
  - 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 17 languages.
  - Personalized Experience: Select your preferred temperature unit, toggle between Light/Dark modes, and set the interface color from 5 distinct themes.
  - 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 (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).
  
  Based on the original concept by François Beaufort; modernized and maintained by François Bacconnet.

  V 2.2: Accessibility & Reliability
  - Optimized for screen readers (WCAG 2.2 AAA).
  - Improved latency tracking.

  V 2.1: Refinement & Personalization
