SidebarX

About

Take control of your bookmarks with SidebarX - the fast, lightweight, and completely private bookmarks manager built for modern web browsers. Whether you're a power user with thousands of saved links or just tired of digging through cluttered bookmark menus, SidebarX gives you instant, native-feeling access to your entire bookmark tree without ever leaving your current page.

What SidebarX Does?
Persistent Side Panel: A dedicated, resizable sidebar docks to your browser - no popups, no floating windows, no losing your place. Toggle it open or closed with a single click or keyboard shortcut.
Instant Search: Type to filter your entire bookmark tree in real time, folders and all, so you find what you're looking for in seconds instead of scrolling through nested menus.
One-Click Folder Control: Expand or collapse every folder at once, or navigate individually, fully keyboard accessible, with dedicated shortcuts for expand-all, collapse-all, and jump-to-search.
Works Everywhere: Built on your browser's native side panel, SidebarX runs on every page, including internal browser pages, where most bookmark extensions simply can't load.

Why You Should Install It?
🚀 High Performance, Virtualized Rendering
SidebarX keeps your bookmark tree fast and responsive whether you have fifty bookmarks or fifty thousand.
🔒 100% Absolute Privacy
Most bookmark extensions demand broad "Host Permissions" to access every website you visit. SidebarX requires zero tracking permissions. All bookmark data is read directly from your browser's native storage and never leaves your device. We do not track, collect, upload, or monetize a single byte of your data.
⚡ Invisible, Set-and-Forget Simplicity
No accounts, no sync servers, no configuration screens. Install SidebarX, pin it to your toolbar, and get a cleaner, faster way to manage your bookmarks instantly.
💸 Completely Free
SidebarX is 100% free to use, with no premium tiers, no paywalls, and no in-app purchases. All features are unlocked from the moment you install it.
