Overview

Your system, as Chrome sees it — presented in a modern, lightweight, and open-source dashboard.

COGext provides a high-level or detailed overview of your system with a single click in your favorite browser. CPU, memory, battery, and network: monitor the essentials at a glance, with further details tucked into a clean, customizable interface. Key Features: * Card-Based Design: An intuitive dashboard layout that keeps the four primary monitors visible while offering simplified access to deep-dive data. * Detailed Views: Real-time load tracking for individual CPU cores, sensor temperatures, display information, Chrome extensions, and storage units (external only for ChromeOS). * Customizable Experience: Choose your preferred temperature unit, toggle between Light/Dark modes, and set your UI "mood" color. * Pure Performance: Built with 100% vanilla JavaScript for maximum responsiveness and minimal resource footprint. * Universal Access: Fully compatible with keyboard, mouse, or touch input. Available in 17 languages. Privacy & Security: - Minimal Permissions: Only 'storage' and 'management' permissions are required. - Network Transparency: A lightweight request is performed every 30 seconds to retrieve your public IP and monitor network latency. This is the only "online" interaction; no personal data or telemetry is ever transmitted or stored. - Privacy First: Your system data stays on your device. Period. - Fully Auditable: COGext is Open-Source (GPLv3). Based on the original concept by François Beaufort; modernized and maintained by François Bacconnet. Changelog: V 2.1: Refinement & Personalization - Code cleanup and optimizations. - Bug fixes. - Added "Moods" (color themes), Sparklines, and latency tracking. - Added support for 15 additional languages. V 2.0: From List to Dashboard - Complete architectural rewrite (MVC). - UI overhaul and new system metrics. - Performance and accessibility improvements. - Full internationalization (i18n) support. V 1.2: Windows bug fixes and icon adjustments. V 1.1: Packaging optimization (integrated fonts). Sources : https://github.com/tchoa91/cog-ext Site : https://ext.tchoa.com
