React Router is designed to work seamlessly with React applications, leveraging React's component-based architecture. It allows for declarative routing, enabling developers to define routes as part of the component tree, making it intuitive to manage navigation within the app.

Vue Router is tightly integrated with Vue.js, providing a smooth experience for managing routes within Vue applications. It utilizes Vue's reactivity system, ensuring that route changes trigger the appropriate updates in the UI.

Single-SPA is framework-agnostic and can integrate multiple frameworks (like React, Vue, Angular) in a single application. This flexibility allows teams to adopt new technologies incrementally, making it suitable for large organizations transitioning to micro-frontend architectures.

React Router supports advanced routing features such as nested routes, route parameters, and dynamic routing. It allows developers to create complex navigation structures easily, enabling better organization of components and views based on the application state.

Vue Router offers features like named routes, route guards, and lazy loading of components. These features enhance security and performance by allowing developers to control access to routes and load components only when needed.

Single-SPA focuses on loading and unloading applications based on the current URL. It does not provide traditional routing features but allows for routing at the application level, enabling different micro-apps to handle their own routing internally while being part of a larger system.

React Router has a moderate learning curve, especially for developers already familiar with React. Its API is intuitive, but understanding concepts like route nesting and hooks may require some time for beginners.

Vue Router is relatively easy to learn for those familiar with Vue.js. Its API is straightforward, and the integration with Vue's reactivity model makes it easy to understand how routing affects the application state.

Single-SPA has a steeper learning curve due to its unique approach to micro-frontends. Developers need to grasp the concepts of application lifecycle management and how to orchestrate multiple frameworks, which can be complex for those new to micro-frontend architecture.

React Router is optimized for performance in React applications. It minimizes re-renders by leveraging React's reconciliation algorithm, ensuring that only the components that need to update are re-rendered when the route changes.

Vue Router enhances performance through lazy loading of routes and components. This means that only the necessary components are loaded when a route is accessed, reducing the initial bundle size and improving load times.

Single-SPA optimizes performance by allowing applications to load only when needed. This lazy loading approach reduces the initial load time and enhances the user experience, especially in large applications with multiple frameworks.

React Router has a large community and extensive documentation, making it easy to find resources and support. Its popularity within the React ecosystem ensures that it is continually updated and improved.

Vue Router benefits from the strong Vue.js community, providing ample resources, plugins, and support. Its close ties with Vue.js ensure that it evolves alongside the framework.

Single-SPA has a growing community focused on micro-frontend architecture. While it may not have as large a user base as others, it is gaining traction as more organizations adopt micro-frontend strategies.
