Strapi
Open-source, API-first headless CMS built on Node.js. Separates content management from presentation, enabling delivery via REST or GraphQL APIs to any frontend.
Overview
Strapi is a developer-friendly headless content management system that eliminates the traditional coupling between backend and frontend. It provides a centralized content management interface while delivering content through APIs, allowing teams to use any frontend framework without vendor lock-in.

- Optional GraphQL API
- CRUD operations on all content types
- Customizable controllers, routes, services
- Lifecycle hooks (beforeCreate, afterUpdate, beforeDelete)
- Custom endpoint support
Plugin System
- Built-in plugins for common features
- Extensible architecture for custom functionality
- Business-logic specific plugins
- Integration with external systems
- Admin panel customization
- Backend feature extensions
Database Layer
- Flexible data relations

- Optimized SQL query generation
- Scalable architecture
Headless & API-First Design
What Makes It Headless
- Content-Presentation Separation: Backend operates independently from frontend
- No Vendor Lock-in: Use any frontend technology (React, Vue, Angular, Next.js, Svelte, etc.)
