Hey everyone 👋 I'm Alexandre, and I built CookieGhost because I was tired of the privacy tool tradeoff: block cookies and half the web breaks, or delete them and get re-tracked 30 seconds later. So I tried a different approach — what if we let cookies exist, but replace their values with convincing fakes? Here's how it works: When a tracker like Google Analytics, Facebook Pixel, or Hotjar drops a cookie, CookieGhost intercepts it before it hits storage and swaps the value for a randomly generated one that's format-correct. A fake _ga value looks exactly like a real one. The tracker accepts it. The website works. But the profile they're building? Pure fiction. What it doesn't touch: Your login sessions, authentication tokens, CSRF protection — all safe. CookieGhost only targets confirmed tracking cookies. A few things I'm proud of: 60+ tracking cookie formats supported (GA, FB, TikTok, LinkedIn, Hotjar, HubSpot, and more) Three protection modes: Aggressive, Balanced, and Gentle Works on Chrome and Firefox (including mobile) Fully open source (MIT), zero data collection, no accounts, no servers The philosophy is simple: don't hide from surveillance — feed it garbage. I'd love your feedback. Try it, break it, tell me what's missing. And if you have a tracker cookie format I should add, open an issue on GitHub.
