SupaSidebar

Universal Browser Integration & Tab Syncing

SupaSidebar seamlessly integrates with all major web browsers, including Safari, Google Chrome, Arc, Firefox, and Brave. It aggregates your open tabs, browsing history, and bookmarks from every browser into a single, unified view. This real-time syncing feature eliminates the need to manually switch between browser windows to find a specific tab, effectively breaking down browser silos and providing a holistic overview of your web activity directly from the menu bar.

Global Keyboard Shortcuts & Command Panel

The application is built for efficiency with system-wide keyboard shortcuts that work instantly from any app. Users can save or copy the current website URL with dedicated shortcuts (Cmd+Ctrl+S / Cmd+Ctrl+C). The cornerstone is the powerful Command Panel (activated via Cmd+Ctrl+K), a spotlight-like interface that allows for rapid searching and launching of any item within the sidebar—be it a file, folder, website, or application—dramatically speeding up workflow navigation.

Native macOS Design & Local-Only Data

SupaSidebar is not a web wrapper or an electron app; it is built as a true native macOS application. This ensures exceptional performance, low system resource usage, and deep integration with macOS aesthetics and behaviors, such as natural swipe gestures. Crucially, all user data—links, files, and organizational structures—is stored exclusively on the user's local machine. Nothing is transmitted to external servers, guaranteeing complete privacy and data security.

Intelligent Organization with Spaces & Recents

The sidebar offers sophisticated organization through a system of "Spaces," allowing users to categorically separate work, personal, or project-specific resources. The "Recents" feature automatically tracks and surfaces every website visited across all browsers within the last 48 hours, acting as a powerful short-term memory aid. Users can also pin favorite items to the top of any list for instant access, ensuring critical resources are always immediately available.

SupaSidebar

Cross-Browser Research and Academic Work

Researchers, students, and analysts often work with dozens of open tabs across multiple browsers for literature review, data collection, and citation management. SupaSidebar consolidates all these disparate tabs and bookmarks into one searchable sidebar. This allows for instant retrieval of any source material without hunting through separate browser windows, significantly streamlining the research process and maintaining a coherent workflow.

Creative and Development Workflow Management

Developers, designers, and content creators juggle project files, design briefs, documentation, and communication tools. SupaSidebar acts as a project dashboard, where users can organize links to Figma files, GitHub repos, documentation, and local project folders into dedicated Spaces. The global command panel allows for launching apps or opening project assets mid-task without leaving the creative flow, enhancing productivity.

Power User and Multitasking Efficiency

For power users, consultants, and managers who multitask extensively across communication apps, web tools, and internal systems, constant app-switching is a major productivity drain. SupaSidebar mitigates this by providing a persistent, always-accessible hub. Keyboard shortcuts enable saving important links on-the-fly, and the unified view allows for quick context recovery, making it ideal for handling rapid-fire tasks and information requests.

Focused Work and Context Preservation

Professionals engaged in deep work sessions, such as writers or programmers, require minimal distractions. SupaSidebar supports this by allowing users to save relevant reference links, documents, or tools to the sidebar for later access without keeping distracting browser tabs open. When needed, the resource can be retrieved instantly via the menu bar or keyboard, helping to maintain a clean desktop and a focused mental state.
