Ghostery — open-source browser extension for blocking ads and trackers.
Ghostery is a fully free, open-source tracker and ad blocker that gives users unusually granular visibility into who is tracking them on any given page. The DB listed it as 'Freemium-Free' and flagged VPN/anti-phishing as paid features — both are outdated: Ghostery discontinued paid tiers entirely, removed user accounts in October 2025, and dropped its standalone mobile browser to focus exclusively on free, account-free browser extensions. Funding is now entirely via voluntary community donations.
Ghostery earns its place by combining best-in-class tracker transparency with zero cost and zero account requirements. The October 2025 account removal and full open-source pivot removed the last meaningful trust concerns for privacy purists.
Default settings are intentionally conservative — users must manually enable stricter blocking to get maximum protection. YouTube and some heavily-scripted sites occasionally break. Firefox performance trails uBlock Origin on pure blocking efficiency.
