Payload is a headless content management system and application framework that uses a code-first approach to define data schemas and administrative interfaces. By utilizing a centralized, type-safe configuration object, it automatically generates database schemas, API endpoints, and a fully customizable admin panel. The system is built on a database-agnostic architecture, allowing it to interface with various storage engines while providing a unified, type-safe API for server-side operations, REST, and GraphQL.

What distinguishes Payload is its deep extensibility and developer-centric design. It allows for the injection of custom React components, views, and widgets directly into the administrative interface, enabling tailored content-authoring workflows. The platform features a robust hook-based lifecycle system for executing custom logic, a comprehensive access control framework for granular field-level security, and a plugin-based architecture that supports complex features like ecommerce, multi-tenancy, and background job processing.

The system provides a broad capability surface, including built-in support for versioned document state management, internationalization, and automated database migrations. It also includes a rich text editor framework that supports custom blocks and markdown conversion, alongside tools for live content previews and media management with various cloud storage adapters.

Payload is designed for TypeScript-native development, automatically generating interfaces from the database schema to ensure type safety across the entire project. The system is configured through a single, fully-typed JavaScript object, and it supports deployment in production environments with features like database-less builds and security hardening.
