Ribbon

Ribbon is a scrolling window manager for Mac. Most window managers fight clutter by shrinking things; Ribbon keeps every window at the width you gave it and lines them up side by side on one strip that runs past the edges of your display. Open another app and it joins the strip as a new column. To get around, swipe with three or four fingers (the strip follows your fingers) or use Control+Option shortcuts. It brings the niri and PaperWM way of working to macOS as a native app, with stacked and tabbed columns, preset widths, a strip per display and per Space that survives restarts, a clickable strip indicator, per-app float rules and a real settings window. Needs only the Accessibility permission, no SIP changes, no account, no telemetry. macOS 13+ on Apple silicon. One-time purchase from $9.99 with lifetime updates.
