SSG vs ISR: Optimizing Next.js Page Delivery

2026-07-17 • 1 min read

Next.js offers distinct page rendering strategies to balance server performance and database loading constraints.

Static Site Generation (SSG) compiles pages into static HTML files during project build steps, delivering instant page loads.

Incremental Static Regeneration (ISR) lets you update static pages in the background after deployments without rebuilding the entire site.

Choose SSG for marketing homepages, pricing grids, and privacy policies that change infrequently.

Select ISR for blogs, product listings, and dynamic client pages where content updates need to show quickly.
