Browse our directory of reviewed Chrome extensions. Safety scores, permission analysis, and detailed reviews for thousands of extensions.
244,000+ Privacy-Reviewed Extensions
Zovo maintains the most comprehensive Chrome extension safety database available. Every extension in the Chrome Web Store has been analyzed for permissions, data access patterns, update history, and developer reputation — producing a safety score from 0 to 100 that gives you an instant read on trustworthiness.
Unlike the Chrome Web Store, Zovo shows you what is actually happening under the hood. We surface hidden risks, flag excessive permissions, and identify extensions that collect more data than they need for their stated purpose.
How Safety Scores Work
Permission Audit
Every permission is classified by risk level — from low-risk storage access to high-risk permissions like reading all website data or modifying network requests.
Data Access Analysis
We review what data each extension can read, modify, or transmit, and flag patterns inconsistent with the extension's stated functionality.
Update Frequency
Extensions that are regularly updated score higher. Abandoned extensions with stale code and unpatched vulnerabilities are flagged.
Developer Reputation
Developers with a portfolio of well-maintained, low-risk extensions earn higher trust scores. First-time publishers are flagged for additional scrutiny.
