Silk

Silk Browser is Amazon's proprietary web browser, developed for its Fire devices, including the Fire tablets and Fire TV. First introduced in 2011, it is built to offer a fast and smooth browsing experience on Amazon's hardware. Silk Browser is unique because it uses a cloud-based architecture, where certain web content is processed and rendered on Amazon’s servers before being sent to the user’s device. This can speed up page load times, especially on lower-end devices, by reducing the load on local processing power. This is considered a security and privacy risk by some.

Silk Browser integrates tightly with Amazon’s ecosystem, providing features like easy access to Amazon services, Kindle content, and a customizable home screen. It also supports standard features like tabbed browsing, private browsing, and password management. While it is designed for Amazon devices, Silk is also available on Android, though it is more commonly used on Amazon's own hardware. Despite being less popular than mainstream browsers like Chrome or Firefox, Silk remains an integral part of the Fire OS experience.
