In the digital age, the distinction between static and dynamic websites is pivotal in shaping the website experience. Understanding static vs dynamic generation, especially in the context of NextJS, is crucial for web developers and designers. This post, inspired by Gosia Widomska’s presentation, dives deep into these concepts, elucidating the key differences, pros and cons, and optimal use cases of static and dynamic sites.

Static Websites: The Bedrock of the Web

Defining Static Web Pages

A static website consists of fixed content delivered to the user exactly as stored. Each page is a separate HTML file, meaning the content remains the same unless manually updated by the webmaster.

Advantages of Static Sites

  • Speed and Reliability: Static sites load faster and are less prone to server-side issues.

  • Security: Less susceptible to cyber-attacks due to the absence of database or complex CMS interactions.

  • Simplicity in Hosting and Scaling: Easier to deploy and handle traffic surges.

Disadvantages of Static Pages

  • Limited Interactivity: Static websites offer less dynamic content and user interaction.

  • Manual Updates: Content updates require manual HTML editing, which can be time-consuming.

Ideal Use Cases Static sites, also known as brochure sites, are perfect for businesses requiring a web presence with the same content for all visitors. Static website design focuses on simplicity and speed, making it ideal for portfolios, digital resumes, and small business websites.

Dynamic Websites: A Leap into Interactivity

Exploring Dynamic Web Pages

Dynamic websites are powered by a server-side language like JavaScript and a database. These sites generate content in real-time, offering a personalized website experience for each visitor.

Advantages of Dynamic Sites

  • Personalization: Tailors content for individual users, enhancing user engagement.

  • Scalability: Easier to manage large sites with a CMS.

  • Real-Time Content Updates: Content can be updated dynamically from a backend system.


  • Complexity: More complex to set up and maintain.

  • Performance Concerns: May load slower than static pages due to real-time content generation.

Ideal Use Cases Dynamic sites shine in scenarios requiring real-time data updates, user personalization, and interactivity. E-commerce sites, social networks, and forums are classic examples of dynamic website design.

Static vs Dynamic Rendering in NextJS

In the realm of web development, particularly when using Next JS, understanding the nuances between static and dynamic rendering is crucial. Here’s a deeper look at how these two types of websites and pages differ in NextJS:

Content Generation Strategy:

  • Static Generation (Static Sites): In NextJS, static generation refers to the process where HTML pages are generated at build time. This means that the page is pre-built and served to each user, identical across requests. Static pages are fast and efficient, ideal for content that doesn't change often, like blog posts or documentation.

  • Server-Side Rendering (Dynamic Sites): Dynamic sites in Next JS utilize server-side rendering. Here, pages are rendered on each request, allowing for personalized and up-to-date content. This method suits scenarios where each user might see different content, like in a user dashboard or a news site with frequently updating stories.

Data Fetching and Handling:

  • Static Sites: Data fetching in static sites is typically done at build time. This means the data used to generate the pages is fixed and remains unchanged unless a rebuild occurs. Static sites are often used when the data doesn’t change frequently, ensuring that the web pages are always ready to be served quickly.

  • Dynamic Sites: Dynamic sites, on the other hand, fetch data on each request. This allows for dynamic content, tailored to individual users or situations. This real-time data fetching is essential for pages that rely on user interactions or live data feeds.

Use of APIs and Databases:

  • Static Sites: In static sites, APIs and databases can be used at build time to source content. However, once the site is built, the content remains static unless the site is rebuilt.

  • Dynamic Sites: Dynamic sites frequently interact with APIs and databases in real-time, allowing for a more interactive and dynamic web page experience. This constant interaction is crucial for sites that require up-to-date information or user-specific data.

Deployment and Caching:

  • Static Sites: Deploying static sites in NextJS is straightforward and often more scalable, as the pre-rendered pages can be served from a global CDN. This results in lower server costs and faster delivery of content.

  • Dynamic Sites: Dynamic sites may require more sophisticated server infrastructure and caching strategies, as they need to handle varied and potentially large numbers of requests, each generating unique content.

SEO and Performance:

  • Static Sites: Generally, static sites have an edge in SEO as search engines can easily index the pre-rendered content. Additionally, they usually have faster load times due to the pre-built nature of the pages.

  • Dynamic Sites: While dynamic sites can be optimized for SEO, it often requires more effort to ensure that dynamically rendered content is search engine friendly. Performance can also vary depending on the server’s response time and the complexity of the data being processed.

Flexibility and Complexity:

  • Static Sites: These sites offer simplicity and are easier to maintain, but they lack the flexibility to provide personalized experiences out-of-the-box.

  • Dynamic Sites: Offer greater flexibility and can provide highly personalized experiences, but they come with increased complexity in terms of development and maintenance.

NextJS and hybrid approach to rendering

With the release of NextJS 13 and the introduction of the app router, parts of our code can be rendered on the server or the client. This flexibility enables the creation of a tailored website experience, leveraging the advantages of both static and dynamic rendering.

Dynamic Rendering Unveiled

What is Dynamic Rendering?

Dynamic rendering, in contrast, is about generating pages on-the-fly, at the time of the user's request. This approach is particularly beneficial for personalized content or when real-time data is paramount.

Benefits of Dynamic Rendering

  • Personalization: Tailors content based on user data.

  • Freshness: Displays up-to-date content.

  • Flexibility: Adapts to user interactions and data changes.

Use Cases

Dynamic rendering shines in scenarios involving user-specific data, such as user profiles or real-time stock prices.

Dynamic Functions and Data Caching in NextJS

Adaptive Rendering Techniques

Next JS intelligently adapts its rendering strategy based on the usage of dynamic functions or requests for uncached data. Dynamic functions depend on information only accessible at the time of a request, such as user cookies, current request headers, or the search parameters in the URL. This adaptability ensures optimal performance and data freshness.

Data Caching Strategies

Understanding when to fetch data, cache, or revalidate is crucial. NextJS offers robust caching and rendering mechanisms, striking a balance between speed and data accuracy.

Best Practices for Static and Dynamic Rendering in Next JS

  • Identify Content Nature: Determine if your content is static or dynamic in nature. Static for unchanging content, dynamic for personalized or real-time data.

  • Leverage On-demand or Time-based Revalidation: Revalidation in NextJS allows you to update static content incrementally or after user interaction without rebuilding the entire site.

  • Optimize Dynamic Rendering: Use server-side rendering or static generation with client-side data fetching for dynamic content to optimize performance.

  • Cache Strategically: Implement caching for static resources and API responses where feasible to reduce load times. By default, NextJS will cache the results of all data fetches, improving performance

  • Monitor and Analyze: Regularly monitor your site’s performance and adjust your rendering strategy accordingly.

Static Website Design: Crafting Timeless Elegance

Static website design, often perceived as the simpler approach to web development, is about creating web pages that deliver the same content to every visitor. However, this simplicity doesn't equate to a lack of depth or potential. In the context of static design, particularly in the realm of NextJS, we see a blend of timeless elegance and modern efficiency.

Fundamentals of Static Design:

  • HTML-Centric Approach: Static sites primarily rely on HTML. This straightforward approach to coding ensures maximum compatibility across browsers and devices.

  • CSS for Styling: Cascading Style Sheets (CSS) play a crucial role in static website design, allowing for aesthetic customizations while keeping the site's static nature.

  • Limited Use of JavaScript: While JavaScript can be used, it's often limited to basic functions like menus or simple animations, maintaining the site’s static character.

Characteristics of Static Website Pages

The world of static website pages is marked by a charming simplicity and uniformity. Each page, meticulously crafted in HTML, delivers the same content to every visitor, creating a sense of consistency and reliability. This consistency is not just in the content but also in the overall user experience, where every interaction feels familiar and intuitive. The speed and performance of static pages stand out, as they load quickly without the need for complex server-side processing or database interactions. This efficiency translates into a more seamless and enjoyable user experience, as visitors can access the information they need without unnecessary delays.

Another defining characteristic of static website pages is their reliability. The straightforward nature of static sites, with fewer moving parts and dependencies, results in a robust platform that's less prone to errors and downtime. Users can count on these pages to be available and functional, providing a dependable source of information or interaction.

Design Principles for Static Sites

In the realm of static website design, a few key principles stand at the core. The first principle is minimalism and clarity, which emphasizes the importance of a clean and uncluttered design. This approach not only makes the website aesthetically pleasing but also ensures that the content is easily accessible and the message clear. Such a design strategy not only enhances user engagement but also aids in the overall usability of the site.

Responsive design is another crucial aspect of static websites. In an age where users access the web from a myriad of devices with varying screen sizes, ensuring that static sites are responsive is paramount. This adaptability guarantees that the user experience remains consistent and high-quality, regardless of the device used.

Lastly, optimization for SEO is a critical design principle for static sites. Their straightforward structure makes them inherently SEO-friendly, as search engines can easily crawl and index their content. By focusing on SEO optimization, static sites can achieve better visibility and reach, making them more accessible to a broader audience.

Advantages in the Context of NextJS

  • Pre-rendering for Performance: Next JS enhances static site performance by pre-rendering pages, ensuring content is quickly accessible to users.

Use Cases and Examples

  • Brochure Sites: Ideal for businesses needing an online presence that provides information without the need for frequent updates.

  • Portfolios and CVs: Professionals can showcase their work and skills effectively using static designs.

  • Event or Product Launch Pages: For pages with a singular focus, static design ensures fast, reliable, and effective information delivery.

Challenges and Considerations

  • Scalability: While static sites are easy to scale in terms of traffic, updating content across multiple pages can be labor-intensive.

  • Dynamic Features: Incorporating dynamic features like contact forms or search functions requires additional tools or services.

Dynamic Website Design: The Art of Real-Time Engagement

Dynamic website design is a journey into the realm of interactivity and personalization. It's where the static elements of traditional web design meet the ever-changing and responsive nature of user interactions and real-time data. In dynamic website design, each page is not just a display of content but a living, breathing entity that reacts and evolves based on user actions and data inputs.

The Essence of Dynamic Design

At the heart of dynamic website design is the use of server-side languages like JavaScript, PHP, or Python, and the integration with databases. This combination allows dynamic sites to generate unique content for each user, creating a personalized experience that static sites can't match.

Responsive and Adaptive

Dynamic sites are inherently responsive, not just in terms of device compatibility but also in responding to user behaviors and preferences. They adapt in real-time, displaying content that aligns with user interactions, such as browsing history or user profiles. This level of adaptability ensures a more engaging and relevant user experience.

Interactive Features

One of the hallmarks of dynamic websites is their interactive features. From complex forms and user forums to e-commerce functionalities and social media integrations, dynamic sites offer an array of interactive elements that engage users actively. This engagement is key to building a loyal user base and improving the overall website experience.

Real-Time Data Handling

Dynamic websites excel in handling real-time data. Whether it's live sports scores, stock market updates, or social media feeds, dynamic sites can update content instantaneously without the need for a page refresh. This capability is essential in today's fast-paced digital environment, where up-to-date information is not just a convenience but often a necessity.

Design Considerations for Dynamic Sites

When designing a dynamic website, several key considerations come into play. The user interface (UI) and user experience (UX) design must cater to dynamic content. This means layouts and elements need to be flexible and adaptable to varying content lengths and types. Navigational elements should be intuitive, allowing users to find their desired content with ease, even as the site's content changes.

Dynamic Content and SEO

Dynamic website design also comes with its set of challenges, especially in terms of SEO. Since content can change frequently, it's essential to implement strategies that ensure search engines can crawl and index dynamic content effectively. Techniques like server-side rendering or progressive enhancement can help in making dynamic content SEO-friendly.

Technology and Tools

Modern website builders and content management systems (CMS) have made it easier to create dynamic websites without deep technical knowledge. These tools offer templates and modules that can be customized to fit various needs, from blogs and news sites to online stores and corporate websites.

Examples of Dynamic Website Design

Examples of dynamic websites are everywhere. E-commerce platforms like Amazon and eBay, social media sites like Facebook and Twitter, and news portals like CNN and BBC are all dynamic sites that cater to individual user experiences.


While static sites offer simplicity and speed, dynamic sites provide interactivity and personalization. As a developer, you do not need to choose between static vs dynamic website and rendering, as NextJS will automatically choose the best rendering strategy for each route based on the features and APIs used. Instead, you choose when to cache or revalidate specific data, and you may choose to stream parts of your UI.
