SupaSidebar

Universal Menubar Sidebar

SupaSidebar transforms your macOS menubar into a powerful, Arc-inspired command center. This elegantly designed panel provides instant, one-click access to your saved links, files, folders, and open browser tabs from any application. It consolidates disparate elements of your workflow into a single, distraction-free interface, eliminating the need to hunt through Finder windows or browser bookmarks. The sidebar is always accessible but never intrusive, living discreetly in your menubar until summoned.

Global Keyboard Shortcuts

The app is built for speed, powered by a suite of intuitive global keyboard shortcuts that work from anywhere on your Mac. Save the current website link with CMD+CTRL+S or copy it with CMD+CTRL+C directly to the sidebar. Instantly open the search panel with CMD+CTRL+K to find any file, folder, website, or app. These shortcuts are designed to minimize mouse travel and context switching, allowing you to execute commands and retrieve information without breaking your concentration or leaving your current application.

Privacy-First, On-Device Storage

SupaSidebar is engineered with a fundamental commitment to user privacy. All your data—every saved link, file path, and organizational structure—resides securely on your Mac. Nothing is sent to external servers or cloud storage unless you explicitly choose to sync via iCloud. This approach ensures your sensitive work materials, research, and personal references remain completely under your control, offering peace of mind alongside powerful functionality.

Intelligent Organization with Spaces & Recents

Organize your digital assets into customizable "Spaces" for different projects, contexts, or workflows. The free plan includes 3 spaces, perfect for daily use, while Pro unlocks unlimited organization. Furthermore, the "Recents" feature automatically tracks every website you've used in the last 48 hours, creating a dynamic, searchable history that helps you instantly find work you were just viewing, preventing valuable links from getting lost in a tab avalanche.

SupaSidebar

The Multitasking Professional

For professionals juggling multiple projects, clients, and communication platforms, SupaSidebar acts as a central nervous system. Quickly switch between project-specific spaces containing relevant documents, dashboards, and communication links. Use global search to pull up a contract, a Slack channel, and a project management board in seconds, all without leaving your email client. This drastically reduces costly context-switching and keeps all project assets organized and immediately accessible.

The Researcher and Creator

Researchers, writers, and content creators who constantly gather sources, references, and assets will find SupaSidebar indispensable.

The "Recents" feature is a lifesaver for retracing your digital steps through hours of research, ensuring no critical source is ever lost in a sea of tabs.

The Tab-Hoarder and Bookmark Collector

For users who habitually have dozens of browser tabs open or maintain a sprawling, unmanageable bookmark bar, SupaSidebar offers liberation. It provides a structured way to save important links without the performance hit of keeping tabs open. Pin favorite items to the top for daily use and let less urgent links reside in an organized, searchable list. This clears mental and digital clutter, leading to a calmer, more focused computing experience.

The Efficiency Enthusiast

Anyone looking to streamline their Mac workflow and reduce repetitive actions will benefit. SupaSidebar eliminates the tedious process of manually navigating to frequently used files or typing out often-visited URLs. By making these resources accessible via consistent keyboard shortcuts from any app, it turns complex navigation tasks into simple, muscle-memory commands, saving countless clicks and minutes throughout the day.
