Arc-like sidebar with nested folders for organizing links

Arc-like sidebar with nested folders, pinned shortcuts, and open tab management for Chrome, Brave, and Edge. Tired of flat bookmarks? Arcsider brings Arc Browser's best feature to any Chromium browser — a persistent sidebar where you organize links in nested folders, pin your most-used pages as a favicon grid, and manage open tabs with drag & drop. What you get: - Unlimited nested folders to organize links by project, client, or topic - Pinned grid — your top links as clickable favicon squares, always visible - Open tabs section — see all tabs and drag them into folders to save - Smart tab focus — clicking a saved link activates the existing tab instead of opening a duplicate - Drag & drop everything — reorder links, move between folders, drag tabs into your tree - Right-click context menus — add any page or link directly from the browser - Export & import — backup your sidebar as JSON, share it across devices - Arc Browser import — migrate your spaces, folders, and pins from Arc's StorableSidebar.json - Keyboard shortcut (Alt+S) to toggle the panel - Dark theme inspired by Arc Zero tracking. Zero analytics. Your data stays in your browser. Open source: https://github.com/jparrill/arcsider
