Blink is the web browser rendering engine used by Google Chrome.
Google announced Blink in 2013 as a fork of WebKit, the rendering engine Chrome had previously used. The change allowed Google and the Chromium project to develop the engine with a different architecture and set of implementation priorities.
Blink is used not only by Google Chrome but also by many Chromium-based browsers, including Microsoft Edge and Opera. It works with Google’s V8 JavaScript engine, although the rendering engine and JavaScript engine are separate components.
A common mix-up is answering Chromium, which is the open-source browser project, or Chrome, which is Google’s branded browser. WebKit was Chrome’s earlier rendering engine and remains associated with browsers such as Apple’s Safari.
