You're already using GraphQL if you use Facebook, Twitter, or other popular services that rely on it. Its popularity is growing rapidly due to its ability to solve real-world problems faced by developers, such as handling multiple clients, mobile development, and microservices architecture. REST cannot provide the same level of abstraction and clean layer between servers and clients that GraphQL offers. As a result, companies like Twitter, Intuit, and Drupal are adopting GraphQL to improve their APIs and developer experience. With GraphQL, developers can enjoy a cleaner API, reduced communication overhead, and better tooling, making it easier for new engineers to learn and use the technology.
