SupaSidebar vs SureThing.io

Universal Browser Integration

SupaSidebar works flawlessly with every major browser you use, including Safari, Chrome, Firefox, Brave, and Arc. This universal compatibility means you can save the current webpage link directly to your sidebar from any browser instantly. No more switching contexts or manually copying and pasting URLs between applications. It creates a unified hub that sits above your browser choice, ensuring your workflow remains consistent and uninterrupted regardless of which window you're in.

Lightning-Fast Global Keyboard Shortcuts

Take control with powerful, system-wide keyboard shortcuts that work anywhere on your Mac. Press CMD+CTRL+S to instantly save the current website link directly to your sidebar.

Intelligent Recents & Pinned Favorites

Never lose your work again. SupaSidebar's "Recents" feature automatically tracks every website you've visited in the last 48 hours, giving you a chronological lifeline back to your research or browsing session.
