The answer lies in how your website’s content is rendered, and that’s where the SSR vs SSG 2025 debate stars.
- Server-Side Rendering (SSR) means your website’s content is generated on the server every time someone visits.
- Static Site Generation (SSG) builds your website pages in advance, turning them into ready-to-serve static files.
Both are powerful methods, but they work very differently, and that difference directly affects scalability and user experience.
Google values both speed and interactivity, so selecting between server-side rendering vs static site generation is a strategic business decision.
This blog is for you to decide which rendering approach fits your next web solution to help your business deliver faster, smarter, and more optimized digital experiences.
What Is Server-Side Rendering (SSR)?
Server-Side Rendering (SSR) is one of the most common and reliable ways to serve content dynamically.
In server-side rendering, every time a user requests a page, the server generates the complete HTML page on the fly and sends it to the browser.
The user immediately sees fully rendered content, and then JavaScript takes over to make the page interactive.
Consider SSR as a web solution that is dynamic and personalized.
SSR Benefits
- Perfect for dynamic content & personalization: Since pages are built in real-time, it’s great for websites showing live data, user profiles, or dashboards.
- Best for frequent content updates: No need to rebuild the entire website whenever content changes.
SSR Drawbacks
- Higher server load: Since each page request triggers a new render, the server works harder under heavy traffic.
- Slightly slower first response on complex pages: Generating pages in real time can delay the initial page load if not optimized well.
We suggest server-side rendering for businesses that rely on dynamic web solutions, such as eCommerce, social platforms, or personalized content websites.
It ensures your users always see fresh content while maintaining great SSR performance with smart caching and CDN strategies.
What Is Static Site Generation (SSG)?
Static Site Generation (SSG) is the approach that powers many lightning-fast modern websites.
In static site generation, pages are pre-built at build time, not on the server for every request.
Tools like Next.js & Gatsby create your web pages ahead of time and store them as static HTML files.
SSG Benefits
- Ultra-fast load times: Since pages are pre-built and served directly from a CDN, users experience near-instant loading.
- Cost-effective hosting: No need for powerful servers; static files can be hosted cheaply or even for free.
- More secure and stable: Fewer moving parts mean fewer vulnerabilities or server failures.
SSG Limitations
- Poor fit for highly dynamic content: If your website content changes often (like product inventory or live news), rebuilding pages repeatedly can be time-consuming.
- Requires rebuilds for frequent updates: Any content change means you must re-generate the static files.
In our experience, static site generation shines for blogs, documentation, marketing sites, and portfolios, where speed matters most, and updates aren’t constant.
When combined with techniques like Incremental Static Regeneration (ISR), SSG can even handle real-time updates while keeping its best performance.
SSR vs SSG: The Core Comparison
The debate around Server-Side Rendering vs Static Site Generation has evolved & it’s no longer just about how you render pages, but how fast & scalable your web solution is.
At Seven Square, we often get asked: “Which one performs better: SSR or SSG?” The truth is, both shine in different ways.
Performance Benchmark: Speed, Caching & Scalability
1. Speed
- SSG wins the speed race because pages are pre-built and served directly from a CDN, making load times almost instant.
- SSR, though slightly slower on first load, offers dynamic, real-time updates that users love.
2. Caching
- SSR relies on smart caching to maintain speed under load, while SSG’s static nature means everything is already cached by default.
3. Scalability
- SSG scales smoothly, no server strain, no database bottlenecks.
- SSR can scale too, but requires strong infrastructure and optimization to handle heavy traffic spikes.
Cost, Maintenance & Infrastructure
- SSR: Needs powerful servers to handle real-time requests, increasing maintenance and hosting costs.
- SSG: Requires less backend management and can be hosted cheaply or on CDNs, making it cost-effective for static or semi-dynamic sites.
If your web solution demands constant updates or personalization, SSR is worth the cost. But if your goal is lightning-fast speed & lower expenses, SSG is the smart choice.
SSR vs SSG Comparison
| Feature | SSR (Server-Side Rendering) | SSG (Static Site Generation) |
|---|---|---|
| Speed | Slightly slower (depends on server response) | Super-fast (pre-built static pages) |
| Scalability | Needs server scaling | Scales easily via CDN |
| Hosting | Requires server setup | CDN or static hosting |
| Content Updates | Real-time updates supported | Needs rebuilds or ISR |
We believe the real winner isn’t SSR or SSG alone, but the right balance between them.
Our web experts often use hybrid rendering, combining SSR’s flexibility with SSG’s speed to build SEO-friendly, scalable, and cost-efficient web solutions.
Real-World Use Cases: When to Use SSR or SSG?
Choosing between SSR and SSG depends on your website’s purpose and audience.
We help businesses choose the best rendering method for their web app based on how often their content changes and how personalized it needs to be.
Use SSR When:
- Building e-commerce sites with frequent updates: Inventory, pricing, and offers change often, & SSR ensures users always see real-time content.
- Personalizing user experiences: For dashboards, profiles, or news feeds, server-side rendering delivers user-specific data efficiently.
- Developing real-time apps: If your app relies on live updates (analytics dashboards, trading platforms, etc.), SSR is the perfect fit.
Use SSG When:
- Creating marketing or blog websites: Pre-rendered static pages mean ultra-fast load times and great performance.
- Building documentation or product pages: Documentation sites like GitHub Docs use static site generation to handle massive traffic with minimal server load.
- Designing portfolios or company websites: SSG provides unmatched speed, security, & stability, ideal for brands that want reliable performance.
