Introduction to Vectrace

Vectrace is an ultra-fast, pure-software vector screen marker and drawing overlay designed for Linux. It provides presenters, educators, content creators, and developers with an instant drawing canvas over their active desktop.

Core Value Proposition

• No GPU Overhead: Built entirely with tiny-skia for predictable performance across low-end and high-end hardware.
• Display Server Agnostic: Operates seamlessly under X11 (via unmapped input shapes) and Wayland (via wlr-layer-shell or XDG protocols).
• Non-Intrusive: Toggle click-through mode anytime (Ctrl+Alt+A or Space) to interact with underlying windows without losing your annotations.
