Next.js features and specs

  • Server-Side Rendering (SSR)
    Next.js supports SSR, allowing pages to be rendered on the server-side before being sent to the client. This results in improved SEO and faster initial page loads.
  • Static Site Generation (SSG)
    Enables pre-rendering pages at build time, which can further improve performance and scalability while allowing for dynamic generation when needed.
  • API Routes
    Next.js allows you to build API endpoints directly in the application, simplifying the process of creating back-end services and endpoints.
  • File-Based Routing
    Offers a simple file-based routing mechanism where the file structure maps directly to the app’s routes, making it easier to manage and understand.
  • Automatic Code Splitting
    Automatically splits code at the page level, reducing the initial load time and improving performance by only loading necessary JavaScript.
  • TypeScript Support
    Built-in support for TypeScript, allowing developers to use static type checking and other TypeScript features easily.
  • Developer Experience
    Provides a great developer experience with features like fast refresh, hot reloading, and detailed error reporting.
  • Rich Ecosystem
    Benefiting from the rich ecosystem of the React community and integrating well with other libraries and tools.
  • Internationalization
    Built-in support for internationalization helps developers build multilingual applications with ease.
  • Community and Support
    Strong community and extensive documentation provide ample support and resources for new and experienced developers alike.

Possible disadvantages of Next.js

  • Learning Curve
    The robust feature set of Next.js can present a steep learning curve for developers who are new to React or server-side rendering concepts.
  • Configuration Overhead
    Although Next.js aims for simplicity, complex projects may still require significant configuration and customization.
  • Performance Overhead
    SSR can introduce additional server load and latency compared to static site generators, especially under high traffic conditions.
  • Deployment Complexity
    Deploying Next.js applications that leverage SSR or API routes may be more complex and could require more sophisticated server infrastructure.
  • Vendor Lock-In
    If heavily relying on Next.js-specific features, moving away from the framework to another solution could require significant refactoring.
  • Bundle Size
    Without careful optimization, client-side bundle sizes can become large, negatively affecting the application’s performance.
  • Build Times
    For large applications, build times can be significant, impacting the development cycle and deployment times.
  • Dependencies
    Next.js introduces its own set of dependencies and tooling, which might complicate version management and compatibility with other tools.

Fly.io features and specs

  • Global Deployment
    Fly.io enables developers to deploy applications geographically close to users, reducing latency and improving performance.
  • CLI and Git-based Deployment
    Fly.io offers a command-line interface and Git integration for quick and efficient application deployment.
  • Automatic SSL
    Fly.io provides automatic SSL/TLS certificates, simplifying secure traffic management.
  • Scalability
    Applications deployed on Fly.io can scale both vertically and horizontally to handle varying loads.
  • Built-in Storage
    Fly.io offers persistent storage solutions such as Fly Volumes, which seamlessly integrate with applications.
  • Integrated Monitoring
    Fly.io provides built-in monitoring tools to track application performance and health.

Possible disadvantages of Fly.io

  • Learning Curve
    New users may find the platform's concepts and deployment methods unfamiliar, requiring time to learn.
  • Documentation
    Users have reported that the documentation can sometimes be lacking in detail or difficult to navigate.
  • Cost
    While Fly.io offers a free tier, the cost can become significant as you scale your applications.
  • Limited Language Support
    Fly.io supports fewer runtime environments and languages compared to more established platforms like AWS or Azure.
  • Platform Maturity
    As a relatively new platform, Fly.io may lack some advanced features and ecosystem integrations offered by more mature competitors.
  • Debugging
    The debugging tools and processes can be less comprehensive compared to traditional cloud providers.

  • I replaced Next.js for my application with this module 🔥
    But I want to say that this topic is clearly not new in 2025, I will not reveal anything supernatural here. HTMX and Alpine.js have already fully proven to everyone that this is not nonsense. I am just retelling everything, but with one interesting remark - this is the HMPL template language which is better than the previous two in some tasks. Next, I will describe why and how it will help you replace Next.js. - Source: dev.to / 5 days ago
