Eww vs Mango Mirror

Eww is a free, MIT-licensed widget system for Linux. It lets you build desktop widgets that work with any window manager, without depending on that manager. You define widget structure, window geometry, behavior, state, and data in the Yuck language. Styling uses CSS or SCSS through GTK’s CSS engine, whose web-CSS support is incomplete for some animations and layout properties. Built-in variables can expose CPU, RAM, disk, battery, network, and time information. Polling variables rerun shell scripts repeatedly, while listening variables update when script output produces a new line. Available widgets include labels, buttons, images, inputs, progress displays, calendars, graphs, tooltips, overlays, stacks, and layout containers. Documentation shows xprop and playerctl integrations. Separate build commands cover X11 and Wayland. Building requires Rust, Cargo, GTK3, Pango, Cairo, and GLib. Window arguments remain constant after opening.

Mango Mirror turns screens into live displays for calendars, weather, photos, news, tasks, menus, and business dashboards. A drag-and-drop editor arranges widgets; users can make multiple pages and schedule content changes by time. Displays can be managed in a browser on a phone, laptop, or tablet, with changes appearing on screen within seconds. Free includes two screen licenses, custom layouts and pages, clock, news, weather, background images, and quotes. Pro supports calendar sources including Google, Outlook, Apple iCal, Cozi, and ICS, plus task and photo services. Business adds office files, PDFs, video, website embeds, and browser snapshots. Enterprise adds Power BI, linked displays, Microsoft 365 group calendars, Teams shared calendars, and advanced snapshots. Supported screens include Samsung and LG TVs, Android/Google TV, Fire TV, tablets, Echo Show, Windows PCs, browsers, and Raspberry Pi. Pro costs $5.99 a month, Business $19.99 a month, and Enterprise $49 a month; each includes three screens. Business includes priority live chat and a 99.9% uptime SLA.
