Stitches is a CSS-in-JS styling framework with near-zero runtime, server-side rendering (SSR) support, and multi-variant capabilities. It provides a powerful way to define and use design tokens, making it easier to maintain consistent styling across large applications. Stitches offers features like automatic critical CSS extraction, which can significantly improve initial load times. Its variant API allows for creating complex component variations with minimal code. Stitches also provides excellent TypeScript support, offering type safety for styles and themes. Its performance-focused approach and developer-friendly API make it a popular choice for projects where styling performance and flexibility are crucial.

Styled-components is a popular CSS-in-JS styling framework that utilizes tagged template literals in JavaScript to style React components. This library allows developers to write actual CSS code to style components, promoting a component-centric styling approach. It automatically generates unique class names, eliminating the need to manually manage class names and selectors. Styled-components offers features like dynamic styling based on props, theming support, and automatic vendor prefixing. This approach results in more maintainable and scalable code by keeping the styles tightly coupled with their components.

JSS (JavaScript Style Sheets) is an authoring tool for CSS that allows developers to use JavaScript to describe styles in a declarative, conflict-free, and reusable way. It provides a more powerful abstraction over CSS, enabling the use of JavaScript's full expressiveness in style definitions. JSS supports features like dynamic styling, theming, critical CSS extraction, and vendor prefixing. By bringing the power of JavaScript to CSS authoring, JSS offers increased maintainability and flexibility in styling complex applications, particularly useful in component-based architectures.
