Tool and Usage

Decentraleyes is a small browser extension. It increases your privacy by blocking specific requests to content delivery networks.

Why this tool?

Most websites consist of HTML show the structure of a website. Together with CSS for styling, and JavaScript for interactive functionality, the website can provide value for its visitors. Some of the used JavaScript libraries are heavy on bandwidth, so website owner may use a content delivery network (CDN). The primary goal for a CDN is to get data closer to the end-user, which results in faster downloads and increasing the performance of the website.

Some common JavaScript libraries are used on many websites. As not every single website creator can pay the costs of a CDN, bigger companies might actually sponsor bandwidth on their CDN edge servers. While this is great from a cost perspective, it also introduces a privacy concern. The owner of the CDN can exactly see what websites a user is visiting by looking at the related requests to the CDN and the related referrer. This is where Decentraleyes comes into place, by intercepting requests to content delivery networks (CDN).

How it works

Decentraleyes looks into the returned HTML data. It replaces external requests to CDNs if it discovers a known JavaScript library. This way the CDN never receives the request. It actually may increase the speed of some websites, yet the main benefit is increased privacy.

Additional information

At this time, Decentraleyes works on Chrome and Firefox.
