Mono Tab

One tab at a time. A calm side panel to organize and navigate your tabs without overwhelm.

Mono Tab keeps you focused by enforcing a simple rule: one tab at a time. When you open a new tab, your previous tab is automatically "parked" — saved and closed, but not gone. All your parked tabs live in a searchable sidebar, ready to restore with one click. KEY FEATURES: • One-Tab Focus Mode Toggle mono-tab enforcement on/off anytime. When ON, opening a new tab automatically parks your current one. Turns off when you close the sidebar. • Favorites Star any tab to pin it to the top. Favorites are protected from auto-parking and always accessible. • Smart Search Instantly find any tab across your open tabs, parked tabs, and recent browsing history. • Time-Grouped Organization Tabs organized by Today, Yesterday, This Week, and Older — so you always know where to look. • Privacy First All data stays local on your device. Nothing is sent to external servers. Your browsing stays private. HOW IT WORKS: 1. Open the sidebar and toggle Mono Tab ON 2. Open a new tab → your current tab gets parked 3. Find your parked tab in the sidebar → click to restore 4. Star important tabs → they stay open and always visible 5. Close the sidebar → Mono Tab turns off automatically Perfect for researchers, writers, and anyone drowning in tabs who wants a calmer browser.
