Traditionally, developers had to pick between Static Site Generation (SSG), which creates pages at build time for maximum speed, or Server-Side Rendering (SSR), which generates content on demand for freshness and accuracy. Both methods offer clear benefits: SSG is highly performant, while SSR ensures real-time data. <\/span>[\/vc_column_text][vc_column_text css=&#8221;.vc_custom_1758876594233{padding-top: 5px !important;padding-bottom: 5px !important;}&#8221;]<span style=\"font-weight: 400;\">In practice, most applications need a mix of both speed and up-to-date information. Incremental Static Regeneration (ISR) is applicable in such scenarios.
