TabStacks is a free Chrome extension that silently organizes your open tabs into collapsible stacks by domain and injects a lightweight switcher bar so you can jump between contexts without the chaos.

• Auto-group by domain — every tab is automatically assigned to a collapsible stack. Ten GitHub tabs? One neat group.
• Switcher bar overlay — jump between stacks instantly without hunting through a sea of favicons.
• Keyboard shortcuts — navigate stacks without touching your mouse.
• Tab search — find any open tab by title or URL. Stop re-opening tabs you already have.
• Theme support — matches your Chrome theme in dark or light mode.
• Fully private — no accounts, no telemetry, no network requests. All state stays on your device.
