In short, the answer is no. Google does not use NextJS for its web applications. Google has its own web development stack, which includes technologies like Angular, Dart, and Polymer, in addition to its own web service platform, App Engine. That said, Google does use React for some of its web applications, but not NextJS.
Google has its own web development stack and is focused on using technologies that it has full control over. NextJS is an open-source framework, which means that Google would have no control over the changes that are made to the framework. Additionally, Google is focused on developing its own technologies, such as Flutter and Angular, which it can control and use to create web applications that are tailored to its needs.
NextJS is used by many companies, including Airbnb, Amazon, Dropbox, and GitHub. These companies use NextJS because it is an easy-to-use and powerful framework that allows them to quickly build and deploy web applications. Additionally, NextJS is optimized for performance, making it a great choice for companies that need to create fast and secure web applications.
To conclude, Google does not use NextJS for its web applications. Google has its own web development stack, web service platform, and technologies like Angular, Dart, and Polymer. Meanwhile, NextJS is an open-source React framework that is used by many companies due to its ease of use and performance optimization.
