Eww vs Monitor Flows

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.

Monitor Flows provides customizable desktop widgets that stay visible while users switch between apps. Its library has more than 50 widgets across nine categories, with examples including weather forecasts, terminal emulators, color pickers, and 3D globes. A drag-and-drop editor arranges and resizes widgets, while settings adjust opacity, blur, accent colors, themes, and backgrounds. Video can keep playing, radio can keep streaming, and web pages can stay loaded as users switch pages. The listed integrations include Spotify, Google Assistant, Philips Hue, Discord, YouTube, GitHub, Twitch, Steam, Slack, Gmail, Yahoo Mail, WLED, and OpenWeather. The app supports Windows 10 and 11, including Home and Pro editions; macOS and Linux support are being explored for the 2026 roadmap. Free includes 15 core widgets, three pages, and five themes, with no time limit or credit card. Pro costs $3 a month; Max costs $49 a year. The FAQ says credentials and configurations are stored locally and that the product collects no telemetry, usage analytics, or personal information.
