Shield — Ad Blocker
Block ads, popups & trackers on every site.
About Shield — Ad Blocker
Shield is a free, lightweight ad blocker for Chrome that removes ads, popups, banners and trackers from every website you visit. It uses 60+ community filter networks to stop intrusive advertising before it loads — so pages open faster, use less data, and stop following you around the web.
Unlike heavy ad blockers, Shield runs entirely in your browser. There is no account to create, no server to talk to, and nothing about your browsing ever leaves your device. Toggle protection on or off in one click, pause it for a specific site you want to support, and watch the counter tick up as it blocks trackers in real time.

Frequently asked questions
Is Shield really free?
Yes — Shield is 100% free, with no account, no subscription and no paywalled features. It's a Codaiman product built to stay free for users.
What does Shield block?
Shield blocks display ads, pop-ups, sticky banners and common ad and tracker networks across the web. It focuses on standard web advertising — some platforms actively fight ad blockers, so results can vary by site.
Will it slow my browser down?
No. Shield is intentionally lightweight and blocks ads before they load, which usually makes pages faster, not slower.
Does Shield collect my data?
Never. There is no login and no server — your browsing and settings stay on your device and are never sent to Codaiman.
How do I allow ads on a site I want to support?
Open the Shield popup on that site and tap “Pause on this site”. Blocking resumes everywhere else automatically.
