miru

miru is a lightweight Wayland zooming daemon designed to fill the ecosystem gap for a reliable screen magnifier. It runs quietly in the background to handle smooth zooming interactions via keybinds, and includes miructl—a platform-agnostic companion CLI for seamlessly toggling modes on the fly. Beyond standard scaling, miru features a dedicated spotlight mode that highlights your cursor while dimming the surrounding area for a distraction-free, focused viewpoint. Fully customizable via a TOML configuration file, you can fine-tune parameters such as your preferred zoom factor, zoom step, spotlight radius, and dimming intensity to suit your workflow. It also has an annotation mode which allows users to draw shapes like rectangles, ellipses, circles and even type text.
