Extension Health Checker

Extension Health Checker scans every extension you've installed in Chrome or Edge and tells you — in plain English — what each one can actually access on your computer. **One-click audit** Instantly see every extension's permissions translated into everyday language: "This extension can read everything you type on any website" instead of "host_permissions: <all_urls>". A clear SAFE / CAUTION / DANGER rating for each one. **2026 risk intelligence** Flags extensions that were silently upgraded from Manifest V2 (the legacy system Google disabled on August 31, 2026) — these often arrive with wider permissions than the original. Warns about extensions with the same "read and change all your data on all websites" permission as known malicious ones that stole millions of users' data this year. **Safer replacements** For every risky extension, the checker suggests a safer, lighter, open-source alternative that does the same job with fewer permissions. **Change Monitor (Pro, one-time $4.99)** Runs a weekly scan in the background. The moment a silent update adds a new dangerous permission — webRequest, proxy, cookies, debugger — you get a notification with exactly what changed. You can revert or uninstall from the popup. **Pre-install scanner (Pro)** Paste any extension's Chrome Web Store URL before you click Add to Chrome. The checker pulls its declared permissions and tells you whether to trust it — before it ever touches your browser. **What you get** - One-click audit of every installed extension - Risk ratings with the reasoning behind them - Plain-English permission translations - Curated safer replacements - Optional weekly monitoring for new dangerous permissions - Optional pre-install scanner so you never install a surprise No account.
