Gatsby has undergone significant advancements since 2019, addressing several misconceptions about its capabilities. The introduction of server-side rendering (SSR) and deferred static generation (DSG) in Gatsby v4 now allows for dynamic functionalities like A/B testing and personalization, dispelling the myth that Gatsby doesn't support dynamic content. Additionally, the platform's ability to handle large-scale sites is evident, as demonstrated by several high-profile websites utilizing Gatsby Cloud to manage over 100,000 pages with rapid build times. Contrary to the belief that Gatsby can't handle live data, it efficiently processes updates from CMS sources like Contentful in seconds and supports live data queries for real-time information, thanks to Gatsby Functions. Moreover, Gatsby Cloud has been optimized specifically for faster build speeds than other hosting services, with recent enhancements like Incremental Deploys further improving performance.
