Utility tool to safely install, test, and manage local CRX extension files in Chrome with permissions review

Chrome restricts direct installation of local CRX files for security reasons. This extension provides a safe, user-friendly way for developers and power users to sideload and test Chrome extensions from local CRX files while reviewing their declared permissions before installation.

1. User selects or uploads a local CRX file via the extension's installer UI (installer.html). 2. Extension uses JSZip to unpack and parse the CRX archive. 3. The extension analyzes and displays the manifest permissions for user review. 4. User confirms installation and the extension installs the unpacked extension into Chrome. 5. The webcrx.io website can also trigger actions via externally_connectable messaging.

Target users: Chrome extension developers / Power users who sideload extensions / QA testers testing unpacked/local extensions

Source code is heavily minified/bundled (Vue.js app), making exact logic flow harder to trace but paid/login patterns are definitively absent.
The connection to webcrx.io could potentially be used for additional features not visible in the current source snapshot, but no evidence of gated functionality.

Monetization

No paid features detected

No evidence of paid features, subscriptions, or payment infrastructure. The 'pro' keyword hits are false positives from minified Vue.js library code (variable names like 'process'). The 'license' hits are open-source license declarations for bundled libraries (JSZip MIT/GPL, pako MIT). No 'premium', 'subscription', 'stripe', 'price', or 'payment' keywords found. The 'upgrade' hit is in generic CommonJS module loader code.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: No login, account creation, or authentication flow detected anywhere in the extension source. The 'auth' keyword hits are all false positives from bundled third-party libraries (loglevel logger, browser-polyfill). No 'login', 'account', or 'sign-in' keywords found. The extension operates entirely locally to install CRX files.

Permission risk

Medium-risk permissions

This estimate uses declared permissions and host permissions to assess access scope and sensitivity.
