What are the alternatives to server-side rendering (SSR)?

• CSR (Client-Side Rendering): All rendering logic occurs in the user's browser using JavaScript. Initially, an empty HTML document is received, which is then filled with content. Suitable for SPAs with high interactivity, but suffers from low SEO and slow initial load.

• SSG (Static Site Generation): Pages are pre-generated on the server as static HTML files during the application's build process. These files are served to the user's browser without additional server processing during the request. Ideal for content that rarely changes (blogs, documentation), providing excellent SEO and speed.

• ISR (Incremental Static Regeneration): Combines the advantages of SSG and SSR. Pages are generated statically but can be incrementally regenerated (in parts) in the background or upon request when new data arrives. Allows updating statically generated content without rebuilding the entire site.

• Pre-rendering: Similar to SSG but usually used for specific pages rather than the entire site. During build, static HTML files are generated for key pages. Other pages are rendered on the client.

Method	SEO	Performance (First Load)	Development Complexity	Interactivity
CSR	Low	Low	Medium	High
SSG	High	High	Low/Medium	Low (client-dependent)
ISR	High	High	Medium	Medium/High
Pre-rendering	Higher than CSR	Higher than CSR	Medium	Medium/High
