Open Ad blocker is a free open source browser extension that filters ad-delivery requests before ads load on a website. Instead of modifying pages, it stops the underlying ad calls, reducing interruptions and page clutter.

Open Adblocker works at the network level, identifying and blocking ad-delivery requests before they reach the browser. Since it is open-source, updates are pushed frequently when websites adjust their ad systems.

Some websites rely on advertising and may restrict access or show notices when an ad blocker is detected. Open Adblocker avoids page modification, but websites can still choose to limit content. You can always pause the ad blocking ability at all times.

Open Adblocker is open-source, meaning its code is public and reviewable. Users and developers can inspect how it works at all times on Github.
