Extension Health Checker

Audit Chrome extensions in one click. See risky permissions in plain English, get risk ratings, and clean up fast.

Ever wondered what your browser extensions can actually see and do? Extension Health Checker audits every installed extension in one click — translating technical permissions into plain English, rating security risk, and helping you clean up with a single click. WHAT IT DOES: • Full security audit — every extension rated High / Medium / Low risk based on the permissions and site access it actually holds • Permissions in plain English — technical permissions like "webRequest" or "cookies" explained in human terms ("Can observe all network traffic, including passwords"), so you finally understand what you've installed • Over-permission detection — highlights extensions that request far more access than their features need (a simple tool asking to read every website?) • Deprecated add-on check — flags outdated Manifest V2 leftovers and suggests modern alternatives from a built-in database of 120+ extensions • Known-extension lookup — cross-references installs against a curated database of 200+ known extensions • One-click actions — enable, disable, or uninstall any extension directly from the results • Search, sort & filter — find extensions instantly, sort by risk level or permission count PRO FEATURES (one-time $4.99 upgrade, no subscription): • Change monitor — get alerted when an extension silently gains new risky permissions after an update (a common way once-trusted extensions turn invasive) • Bulk operations — disable or uninstall multiple extensions at once • Weekly auto-scan — automatic health checks with desktop notifications • Extension history — complete log of installs, updates, uninstalls & permission changes • Pre-install scanner — look up an extension against the security database BEFORE you install it All scanning runs locally in your browser.
