Introduction
Next.js has been the go-to framework for building production-grade React applications for years. From startups to tech giants, developers have praised its seamless support for server-side rendering (SSR), static site generation (SSG), and its file-based routing system.
However, recent developments have raised concerns over longer development server boot times, slower builds, and even frequent crashes during development.
In fact, a recent migration case study from Flightcontrol noted: Every 20 minutes or so, you have to restart the dev server because it crashes. And before it crashes, it progressively gets slower as you make more changes.”
In this blog, we’ll be highlighting the major Next.js vulnerabilities and why major companies are considering moving out of Next.js.
7 Reasons Why Companies are Thinking of Moving Off Next.js!
1️⃣ Complexity with App Router and React Server Components
The introduction of the App Router and React Server Components (RSC) in Next.js aimed to enhance performance and developer experience. However, these features have become next.js vulnerabilities because of their complexity, and some developers find them challenging.
For instance, the App Router’s handling of server and client components can lead to confusion, especially when dealing with navigation and data fetching. Additionally, the mental model required to effectively use RSCs differs significantly from traditional React practices, leading to a steeper learning curve.
2️⃣ Performance Concerns
Despite Next.js’s reputation for performance, some developers have reported Next.js issues with performance, particularly with development server speed and build times. The integration of new features like RSCs and the App Router has, in some cases, led to slower builds and increased memory usage.
For example, developers have noted that the development server can become sluggish, requiring frequent restarts due to memory leaks. This hampers productivity and can be frustrating during development.
Did you know, as per Github, Dynamic routes in App Router are reportedly 4x slower to load than those in the older Pages Router
3️⃣ Limited Flexibility and Customization
Next.js provides a set of conventions and built-in features that streamline development. However, these conventions can sometimes limit flexibility, making it challenging to implement custom configurations or workflows.
For companies with unique requirements or those needing fine-grained control over their applications, this Next.js vulnerability can be a hindrance. Customizing aspects like routing, data fetching, or build processes may require workarounds or significant effort.
4️⃣ Vendor Lock-In Concerns
Next.js is developed and maintained by Vercel, and while it’s open-source, some developers express problems with Next.js’s potential vendor lock-in. Features like Image Optimization and Middleware are tightly integrated with Vercel’s platform, which can make migrating to other hosting providers more complex.
This tight coupling may deter companies seeking to maintain flexibility in their infrastructure choices.
5️⃣ Unstable Development Experience During Migration
Companies that began adopting the new App Router and RSC model mid-project often report a disjointed developer experience. Many teams find themselves working with both the old Pages Router and the new App Router simultaneously, creating inconsistencies in routing logic, layout handling, and data-fetching methods.
This next.js issue of hybrid state makes it harder to onboard new developers or maintain code consistency, especially in larger teams.
6️⃣ Increased Debugging and Tooling Challenges
The abstraction and complexity introduced by RSCs and server/client boundaries also pose challenges for debugging and observability. Standard browser dev tools often fall short in offering meaningful stack traces or a clear separation of server vs. client components.
Additionally, another problem with Next.js is that many popular monitoring and logging tools still lack deep integration with the latest Next.js features. This disconnect can slow down bug fixing and result in longer QA cycles, increasing the overall cost of development.
7️⃣ Over-Optimization for Specific Use Cases
Next.js’s evolution seems increasingly aligned with Vercel’s product vision, which can be frustrating for companies with different infrastructure goals. For example:
- Features like Edge Middleware, Incremental Static Regeneration (ISR), and Image Optimization are tailored to Vercel’s edge network.
- Running these on platforms like AWS, Netlify, or your own servers often leads to degraded performance or extra setup overhead.
This has nudged companies toward agnostic frameworks like Next (for Vue), Remix, and SvelteKit, which emphasize developer freedom and adaptability.
Conclusion
Next.js remains a powerful tool for building React applications, and its features continue to evolve. However, due to some complex features and Next.js vulnerabilities, many companies are considering moving out of Next.js.

Frequently Asked Questions(FAQs)
Many companies that have moved off Next.js or are considering it are choosing frameworks like Remix, Astro, Vite, and SvelteKit. These alternatives offer better flexibility, simpler mental models, and often faster development experiences, which address some of the Next.js issues raised by the community.
You can prevent unnecessary renders in React by using React. Memo, useCallback, useMemo, and ensuring proper state management help improve overall app performance.
Yes, many developers find that moving away helps. The problem with Next.js often lies in its opinionated structure and Vercel-specific optimizations. Alternatives like Remix or Astro allow more control over routing, server-side logic, and infrastructure decisions, improving app flexibility.
Definitely. With features like Incremental Static Regeneration (ISR), dynamic server functions, and middleware, hosting costs for complex Next.js apps can spike, especially on non-Vercel platforms. Server costs and Next.js vulnerabilities when it comes to performance have been a major factor in why companies are moving away from Next.js.
