BrowserVet scans every Chrome extension you have installed, analyzes their permissions, and gives you a clear trust score so you know which ones are safe — and which ones are a threat.
BrowserVet gives you complete visibility into what your Chrome extensions can access and whether you should be concerned.
Every extension gets a composite score based on 6 weighted security factors. See at a glance which extensions you can trust and which you should investigate.
Get notified instantly when an extension silently adds new permissions after an update. Never get caught off guard by permission scope creep.
Extensions are categorized into Low, Medium, High, and Critical risk tiers based on the sensitivity of their requested permissions.
Disable or remove risky extensions directly from the BrowserVet dashboard. No need to dig through chrome://extensions.
Schedule scans every 1-24 hours. BrowserVet monitors your extensions continuously and alerts you of any changes — even when the popup is closed.
Export detailed security audit reports as PDF with full trust score breakdowns, permission analysis, and risk assessments for every extension.
No accounts. No setup. Just install and click scan.
Add BrowserVet from the Chrome Web Store. It requests only 4 minimal permissions — all justified and transparent.
BrowserVet analyzes every installed extension, checks permissions, computes trust scores, and identifies risks in seconds.
Review your results, disable risky extensions with one click, and export a PDF report. Background scans keep you protected 24/7.
Each extension is evaluated across multiple dimensions for a comprehensive risk assessment.
| Factor | Weight | What It Measures |
|---|---|---|
| Permission Scope | 30% | How sensitive are the permissions this extension requests? |
| Publisher Trust | 20% | Is the developer verified, reputable, and well-known? |
| Update Recency | 15% | Is the extension actively maintained with recent updates? |
| Permission Justification | 15% | Do the permissions make logical sense for the extension's purpose? |
| User Base | 10% | How many users have installed and trusted this extension? |
| Review Sentiment | 10% | What do other users say in their ratings and reviews? |
BrowserVet is built with a strict privacy-first architecture. We believe a security tool should never be the thing you need security from.
All data is processed entirely inside your browser. Nothing ever leaves your device. Not even metadata.
BrowserVet makes no HTTP requests, no WebSocket connections, and no calls to any server. Verify in DevTools.
Remove the extension and all data is gone instantly. No traces, no hidden files, no residual tracking.
We request the absolute minimum: management, storage, alarms, and notifications. Every single one is justified.
