Auto Freedium Redirect for Medium (0-Interaction)

Chrome extension (Manifest V3) that automatically redirects Medium "Member-only story" articles to https://freedium.cfd/<full-original-url> on whitelisted domains.

Demo

Whitelisted domains

• medium.com and subdomains
• infosecwriteups.com

How to install (developer mode)

1. Open Chrome at chrome://extensions/.
2. Enable Developer Mode (top-right).
3. Click "Load unpacked" and select this project folder.

Settings UI

Click the extension icon in the toolbar to open the settings popup where you can:

• View current whitelisted domains
• Add new domains to the whitelist
• Remove domains from the whitelist
• Settings are automatically saved and synced across devices

How it works

• A content script observes the DOM (including SPA dynamic loads) and looks for the text "Member-only story".
• When detected, it redirects once to https://freedium.cfd/<full-original-url> using location.replace and adds the ?freedium-redirected=1 flag to the original URL to avoid loops.

Notes

• The script only runs on whitelisted domains declared in manifest.json.
• It does not collect data or modify content, it only redirects when necessary.
