Strapi is a popular headless CMS that offers built-in content management features, making it easy to create, edit, and manage content for various platforms. It provides an API-driven approach, ensuring fast and reliable content delivery with performance optimizations and scalability considerations. Strapi's plugin system and extendable API allow developers to customize its functionality to meet project needs. In contrast, back-end frameworks like Express.js, Django, and Laravel offer greater flexibility in designing custom application logic, integrating with external systems, and providing full control over development and architecture. The choice between Strapi and a back-end framework depends on factors such as project requirements, team expertise, budget, and resources. Strapi is suitable for content-heavy applications, multi-platform content distribution, and quick setup, while back-end frameworks are better suited for complex projects with custom logic, integration with external systems, or full control over development and architecture.
