WebAPI Blocker

Easily block (nullify) undesired Web API(s) and improve your privacy.

WebAPI Blocker is a lightweight Chrome extension designed to give users control over their browsing experience by allowing them to block or nullify specific Web APIs. Through a user-friendly popup UI, you can select undesired APIs from a dropdown list and add them to a block list. Items can be deactivated, removed, and managed efficiently, ensuring granular control over which APIs are active.

Additionally, the extension offers a whitelist for particular domains, allowing flexibility to retain API functionality where needed. A reload button helps apply changes instantly. While this extension enhances privacy by limiting potentially invasive browser APIs, users are advised to research before disabling APIs, as blocking some can affect website functionality. Bugs can be reported on the official homepage.

User reviews

Like the concept and the effort. But need to have some pre-prescribed settings to make things easy for non-techies. Disabling for say 5 min as an option to switching on and off. Also, some indicator showing that it is this extension that may be breaking or blocking the site. Thanks.

some website like keycombiner has a timer while practicing. so, i use this extension to block the settimeout api, but then the website just stops loading the page. it would have been worked if it had an option to stop an web api while working instead of blocking from the start, then the page would start normally and would worked correctly.
