In this blog, we’ll dive into five real-world applications that leverage the power of Next.js and unpack valuable lessons you can apply to your own projects.
Introduction
When it comes to web development in 2025, performance, scalability, and user experience are non-negotiable. The Next js Framework was designed with all of these in mind. It combines the best of static and dynamic rendering with intuitive routing, built-in image optimization, and SEO-ready architecture.
However, understanding its potential isn’t just about reading documentation real-world applications give you context. By exploring how companies like Netflix, Notion, and TikTok implement Next.js, you can uncover practical insights that go far beyond theory.
Why Real-World Examples Matter
You’ve probably seen tutorials or blog posts about how to set up a Next.js project. But real-world implementations show how teams scale those projects to support millions of users.
Here’s why real-world examples are valuable:
Practical Use Cases: They showcase how actual businesses solve problems using the Next js Framework.
Scalable Architecture: They offer insight into structuring your app to handle real-world traffic.
Performance Benchmarks: You learn how to keep pages fast and efficient under heavy load.
Learning from real companies helps you avoid common mistakes and adopt battle-tested solutions.
Top 5 Applications Built with the Next js Framework
1] Netflix Jobs
What It Is:
Netflix’s career site, jobs.netflix.com, is a globally accessed platform for potential hires to browse roles, read about teams, and apply for jobs.
Why They Use Next.js:
SEO Optimization: Since job listings need to appear in Google searches, server-side rendering ensures each page is crawlable and indexed correctly.
Consistent Performance: With thousands of listings and dynamic content, using static generation where possible ensures the site loads fast even with a large content base.
Internationalization: Netflix hires worldwide, and Next.js’s built-in i18n routing allows the site to easily support multiple languages and regions.
What You Can Learn:
If you’re building a site with content that needs to be discoverable by search engines and consumed globally, the Next is Framework offers scalable internationalization and SEO out of the box. You can use static generation for pages that don’t change often and revalidate them periodically with Incremental Static Regeneration (ISR).
2] Notion
What It Is:
Notion is a popular all-in-one productivity app for note-taking, team collaboration, databases, and more. They use Next.js for their marketing pages and documentation.
Why They Use Next.js:
Fast Iteration for Content Teams: Next.js makes it easy for non-developers to push updates to static content without rebuilding the entire application.
Optimized Asset Handling: With the built-in Image component, Notion ensures quick loading of illustrations, screenshots, and icons without needing to manually compress them.
MDX & Static Export: Their documentation is built using MDX, allowing developers to write docs in Markdown and embed React components when needed.
What You Can Learn:
You don’t need to build an entire app in Next.js use it for your documentation, landing pages, or help centre. The framework’s support for Markdown and component reusability makes it ideal for developer-friendly content platforms.
3] TikTok Web
What It Is:
While TikTok is mostly known as a mobile app, its web version (especially landing pages, user profiles, and video links) uses the Next js Framework.
Why They Use Next.js:
Dynamic Routing at Scale: Each user profile or video has a unique URL. Next.js’s file-based routing makes creating millions of individual, SEO-friendly pages seamless.
Incremental Static Regeneration (ISR): TikTok benefits from ISR to pre-render pages at build time and then update them in the background as new content is posted.
Optimized Performance: TikTok needs pages to load instantly. Next.js ensures that by only sending the JavaScript necessary for the current page (thanks to automatic code splitting).
What You Can Learn:
If your app involves lots of user-generated content, you’ll benefit from the flexibility of dynamic routing and ISR in Next.js. Instead of pre-rendering every page on each deploy, you can regenerate only the ones that change, improving efficiency.
4] Hashnode
What It Is:
Hashnode is a blogging platform that allows developers to publish articles directly on custom domains, while offering features like syntax highlighting, GitHub integration, and analytics.
Why They Use Next.js:
Multi-Tenant Architecture: Each user gets a unique blog with a subdomain or custom domain (like yourname.dev). Next.js's dynamic routing and API routes make this setup possible.
SEO for Every Blog: Each article benefits from SEO metadata, social sharing tags, and structured data all supported by Next.js’s SSR and Head API.
Custom Markdown Support: Writers use Markdown or MDX, enhanced with custom components like callouts, code blocks, and embedded tweets.

Using the Next js Framework, you can build highly personalized user experiences like individual dashboards, blogs, or storefronts without sacrificing performance. Dynamic routing, server rendering, and customizable metadata make it all seamless.
5] IGN
What It Is:
IGN is a high-traffic gaming and entertainment news site that uses the Next js Framework for content delivery across its editorial and media-heavy sections.
Why They Use Next.js:
Scalable Publishing Workflow: Writers can push new content that’s instantly available and pre-rendered for fast viewing.
CMS Integration :IGN connects its headless CMS to Next.js to pull and serve articles via static generation, ensuring fast load times even for older content.
Advertising and Analytics: Next.js enables script control to avoid performance bottlenecks caused by third-party ad tags or tracking scripts.
What You Can Learn:
When handling a content-rich website or blog, integrating Next.js with a headless CMS such as Contentful, Strapi, or Sanity allows you to scale efficiently while maintaining strong performance. Plus, you have full control over third-party scripts to prevent bloat.
Key Takeaways for Developers
1. Prioritize Performance from Day One
All of these applications leverage the Next.js Framework to deliver quick and responsive user experiences. Static generation, SSR, and image optimization contribute to superior user experience. This proves that performance isn't just a bonus it's essential.
2. Build for Global and Scalable Use
From Netflix's multilingual job site to TikTok’s millions of dynamic URLs, the Next js Framework proves it's capable of handling both scale and complexity. Its i18n and routing features let you expand globally without rearchitecting your app.
3. Content + SEO = Growth
Every app here leverages SEO benefits, especially for landing pages and blogs. Next.js makes this easy with SSR, and dynamic metadata capabilities.
4. Integrate with Headless Tools
Headless CMSs are the future, and Next.js fits right in. From content and e-commerce to analytics, you can seamlessly incorporate top-tier tools to build a flexible, modular architecture.
5. Flexibility is Key
You don’t have to build everything dynamically or statically Next.js allows you to mix both. Apply static generation for pages that don’t change often, and opt for dynamic rendering when real-time data or user-specific content is required.
Conclusion
Next.js is more than just a frontend framework it's a robust solution for building high-performance, scalable web applications designed to meet real-world requirements. The achievements of platforms such as Netflix, Notion, TikTok, and Hashnode highlight the powerful results that can be achieved with the right development strategy.
Exploring these applications helps you go beyond basic features and gain practical insight into how to use them successfully.
