Find what's slowing your browser. Fix it in one click.
What it does
Health Score
Instant 0-100 score based on your extension load, orphaned entries, and permission sprawl.
Heavyweight Detection
Flags extensions using aggressive permissions like webRequest, all-URL host access, and sideloaded installs.
Orphan Scanner
Finds leftover entries from extensions you uninstalled months ago that are still cluttering your browser config.
Deep Clean
Full-screen guided cleanup: clears HTTP and Service Worker caches, disables bloat, and shows live progress.
Protected Extensions
Password managers, security tools, and your browser's built-ins are automatically safeguarded from cleanup.
Benchmark
Before-and-after DOM and JS benchmarks so you can see the actual performance difference.
How it works
Scan
Click the icon. Get your health score and a breakdown of every extension's impact.
Deep Clean
One button clears caches, flags heavyweight extensions, and lets you disable them in bulk.
Finish with Pro
Pro runs a verified native tool to remove orphaned config entries and disk-level caches extensions can't touch.
Deep Clean Pro
Extensions are sandboxed. They can't touch browser config files or disk-level caches. Pro runs a verified native tool that finishes what the extension started.
