SupaSidebar

Universal Capture with Global Shortcuts

This is the killer feature that makes SupaSidebar indispensable. No more tedious right-clicking or dragging. From any browser—Safari, Chrome, Firefox, Brave, or Arc—you can instantly save or copy the current webpage's URL using configurable global keyboard shortcuts (like Cmd+Ctrl+S to save). It works system-wide, meaning you're never more than a keystroke away from capturing important information without breaking your flow. This seamless integration is what transforms SupaSidebar from a passive storage app into an active productivity powerhouse.

SupaSidebar brilliantly keeps track of your activity. The "Recents" section automatically logs every website you've visited in the last 48 hours, acting as a perfect short-term memory for when you inevitably close a tab too soon. More impressive is the universal search (triggered by Cmd+Ctrl+K). This isn't just for your saved items; it's a blazing-fast conduit to find any file, folder, website, or application on your Mac instantly. It eliminates the friction of switching between Finder and your browser, centralizing access in one focused command palette.

Spaces for Organizational Freedom

Moving beyond a simple list, SupaSidebar introduces "Spaces"—separate, organized lists to categorize your work. The free plan includes 3, which is perfect for dividing personal, work, and research tasks. The Pro plan unlocks unlimited Spaces, allowing for meticulous organization by project, client, or topic. This structure ensures your sidebar remains clean and relevant to the task at hand, preventing it from becoming a digital junk drawer. It’s the organizational layer that makes the tool scalable for power users.

Native Mac Design & Privacy-First

SupaSidebar feels like a natural part of macOS. It's not a clunky port or a web wrapper; it's built specifically for the Mac ecosystem, with smooth animations and intuitive interactions like natural swipe gestures. Crucially, it operates on a staunch privacy-first principle: all your data—links, files, metadata—stays locally on your Mac. Nothing is sent to external servers. You get the convenience of cloud-like organization with the absolute security and privacy of local storage, which is a rare and commendable combination.

Use Cases

Mailopoly

Managing Busy Schedules

For professionals juggling multiple responsibilities, Mailopoly simplifies life management by organizing emails related to meetings, deadlines, and tasks. You can effortlessly track important commitments, ensuring you never miss a critical appointment or deadline again.

Efficient Side Hustle Management

Entrepreneurs balancing side hustles alongside full-time jobs will find Mailopoly invaluable. The platform allows users to manage communications from different accounts in one place, streamlining workflow and making it easier to respond to clients and partners promptly.

Simplifying Personal Finances

Mailopoly can assist users in keeping track of bills and invoices. By extracting financial details directly from emails, it helps you stay on top of your payments and ensures you are well-informed about upcoming expenses, thereby reducing financial stress.

Stress-Free Travel Planning

Travelers will appreciate Mailopoly’s ability to compile booking confirmations, flight details, and itinerary changes in one accessible location. With automatic reminders and updates, it eliminates the hassle of searching through multiple emails for travel-related information.

SupaSidebar

The Academic Researcher

For anyone writing a paper or thesis, SupaSidebar is a game-changer. You can instantly save source articles from various databases and browsers into a dedicated "Research" Space. Use the Recents feature to jump back to a statistical tool or journal website you used yesterday. Keep PDFs and data folders pinned for quick access. It turns the chaotic process of literature review and source management into a streamlined, centralized operation, saving hours of tab-hopping.

The Content Creator & Digital Marketer

Creators constantly collect inspiration, draft social posts, manage assets, and track analytics. SupaSidebar allows you to pin your Canva dashboard, YouTube Studio, and brand assets folder. Save competitor links or inspiration from around the web with a single shortcut. Use different Spaces for different clients or platforms (e.g., "Client A - Instagram," "Blog Ideas"). The universal search lets you pull up a brand logo or a draft document mid-task without ever leaving your creative flow.

The Multi-Browser Power User

Many of us use different browsers for different purposes—Chrome for work, Safari for personal, Firefox for testing. SupaSidebar eliminates the friction between them. No matter which browser you're in, your universal sidebar remains constant. You can save a link from your work browser and access it instantly while browsing personally in another. It creates a cohesive layer above your browser choice, making your workflow browser-agnostic and far more efficient.

The Project Manager or Consultant

Juggling multiple clients or projects means context switching is a major productivity killer. With unlimited Spaces (on Pro), you can have a dedicated Space for each client or project, containing all relevant links to project management tools (Asana, Trello), shared drives, communication apps (Slack, Teams), and key documents. Switching mental contexts becomes as simple as clicking a different Space in your sidebar, keeping everything you need neatly compartmentalized and instantly accessible.

SupaSidebar FAQ

Is SupaSidebar a browser extension?

No, and that's part of its genius. SupaSidebar is a standalone macOS application that lives in your menu bar. It works independently of your browser, which is how it achieves universal compatibility with Safari, Chrome, Firefox, Brave, Arc, and others. It uses system-level accessibility features to capture the active browser tab's URL, meaning you don't need to install a separate extension for each browser you use.

Which browsers does SupaSidebar work with?

SupaSidebar is designed to work seamlessly with all major browsers on macOS. This includes Safari, Google Chrome, Mozilla Firefox, Brave, and Arc. The application detects the frontmost window, so as long as you're using one of these browsers (or most other modern browsers), the global keyboard shortcuts will capture the current page's URL correctly.

Where is my data stored?

All your data is stored locally on your Mac. SupaSidebar operates on a strict privacy-first model. Your saved links, files, folders, and organizational structures never leave your computer and are not synced to any cloud server unless you choose to use iCloud or another service to sync the application's data folder yourself. This ensures complete privacy and security.

Is there a free trial?

Yes, absolutely. You can download and use SupaSidebar for free forever with a feature-rich free plan that includes 3 Spaces. Furthermore, the "Pro" features are available to everyone on a full, no-credit-card-required 7-day trial. This lets you test drive unlimited Spaces and all premium capabilities to see if the upgrade is right for your workflow before making any financial commitment.

SupaSidebar Alternatives

SupaSidebar is a Mac-focused productivity tool designed as a sleek sidebar for instantly saving and accessing links, files, and folders. It falls squarely into the category of workflow and tab management software, aiming to reduce digital clutter and streamline your daily computer use.
