Overview

PauseCat is a professional-grade Windows utility engineered in Rust and powered by WebView2 to provide a seamless, non-intrusive break experience. Designed for high-performance workstations, it ensures consistent health intervals without interrupting productivity with inefficient or flickering overlays.

Key Features

Advanced Visual Engine

• High-Fidelity Overlays: Utilizes a GDI-based screen capture and pure Rust Gaussian blur implementation for instantaneous, flicker-free break transitions.

• Glassmorphic UI: Hardware-accelerated WebView2 host providing a modern, semi-transparent interface with smooth animations and interactive components.

• Native UX Hardening: Comprehensive protection against accidental gestures and system-level input interference to maintain application focus.

Intelligent System Integration

• Session Awareness: Monitors Windows Terminal Services (WTS) notifications to detect session locks, unlocks, and system sleep states, automatically pausing and resuming the timer.

• Media Control Synchronization: Integration with System Media Transport Controls (SMTC) to intelligently manage background media playback during active break sessions.

• Theme Synchronization: Real-time synchronization with Windows system theme preferences for a cohesive desktop experience.

Technical Excellence

• Optimized Performance: Low-overhead Rust implementation resulting in a minimal memory footprint and a compact binary size of less than 2.5 MB.

• Reliable State Management: Event-driven architecture powered by a central state machine to ensure consistent behavior across complex system events.

• Automated Update Pipeline: Integrated update engine for secure version management and automated deployment via GitHub Releases.

• Robust Input Validation: Enforced configuration limits and sanitization for work and break durations to ensure application stability.
