What is KeystoneJS?
KeystoneJS is an open-source, programmable content management system and application backend built on Node.js that provides a powerful GraphQL API and an auto-generated Admin UI from schema definitions. Keystone uses a declarative schema-driven approach where you define your data model, access control, and hooks in TypeScript, and the platform generates a complete GraphQL API, database schema (PostgreSQL or SQLite via Prisma), and a polished Admin UI. The Admin UI features rich text editing with a customizable Slate-based document field, relationship management, image and file uploads, and custom React components for field views. Keystone's access control system supports item-level and field-level permissions with filter-based access patterns. The platform includes session management and authentication out of the box. Virtual fields enable computed properties, and hooks (beforeOperation, afterOperation, resolveInput) provide lifecycle hooks for custom business logic. Keystone integrates with any frontend framework and can be deployed on any Node.js hosting platform.
