AnyLink is a cloud-based emulation service that allows users to simulate different network conditions for web browsing. Developed by AnyLink, this free Chrome add-on is designed to help developers and testers understand how their websites perform under various network scenarios.

With AnyLink, users can forward their traffic through different network links, such as a 3G connection or a DSL connection, to accurately replicate real-world browsing experiences. By doing so, developers can identify and address any performance issues that may arise in different network conditions.

AnyLink utilizes Facebook's Augmented Traffic Control to accurately emulate network links, ensuring that the emulation is as close to reality as possible. The add-on also makes use of network cookies to express which link to use for the emulation.
