Have you ever noticed your computer lagging, your laptop battery draining, or your system fans screaming like a jet engine? Most of the time, the culprit isn't your computer—it's the dozens of forgotten browser tabs running quietly in the background.
tabDelta turns your browser into a clean performance dashboard. It acts just like a computer task manager, showing you exactly which tabs are eating up your computer's speed and where your active time is going.
Best of all? It is 100% private. All data stays entirely on your own device and never touches the cloud.

You shouldn't have to guess why your computer is suddenly running slow. tabDelta constantly watches your open tabs in the background.
- Custom Thresholds: You set the performance limits that match your computer.
- Instant Notifications: The exact moment a background tab goes rogue—like a heavy social media feed or a hidden video streaming in the background—tabDelta sends you a direct desktop notification.
- Speed Up Your PC: Instantly know exactly which specific tab to consider closing to free up your memory and recover your computer's speed.
Traditional tools just track your passive history links, which doesn't tell the true story. tabDelta intelligently maps out your actual human focus.
- Active Engagement: It measures real interaction (like active scrolling, typing, or moving your mouse).
- Automatic Background Pausing: The exact second a tab is hidden or pushed into the background, its attention tracking drops to zero.
- Focus Badges: Easily view your time cleanly split into Deep Work, Focus, or Idle so you can see where your energy is actually going.
Ever wonder why your internet data is running out so fast? tabDelta features a visual internet monitoring panel.
- See exactly how many Megabytes (MB) each tab downloads and uploads during your browsing session.
- Automatically organizes website traffic into helpful buckets like Streaming Video, Images, or Hidden Tracking Scripts so you can spot bandwidth hogs.
tabDelta was built for personal insight, not surveillance. Because your data belongs to you, our architecture follows a strict Local-First design:
- Zero Cloud Servers: We maintain no remote servers, require no user accounts, and have no login screens.
- No Data Selling: Because your data never leaves your physical machine, it is physically impossible for us to track, share, or sell your browsing history to third-party advertisers or data brokers.
- Safe Cleanups: The extension features an automatic 90-day cleanup loop to keep your local drive light, alongside a one-click "Clear Data" button to hard-wipe everything instantly.
