Keystone turns TypeScript schema definitions into a complete GraphQL API and React Admin UI automatically, eliminating the gap between data modeling and application scaffolding. Nearly 10,000 GitHub stars and over 270 contributors across a decade of development back a framework where list definitions map directly to Prisma models on PostgreSQL or SQLite, generating database migrations and exposing every field relationship through Apollo Server's GraphQL endpoint. Granular access control operates at the list, field, and operation level with filter-based restrictions that limit which records users can see, create, update, or delete based on session data and custom logic. The document field provides a structured WYSIWYG editor with content blocks, inline relationships, and custom React components that render consistently across the Admin UI and frontend applications. Event hooks fire before and after create, update, and delete operations for validation, side effects, and external service integration. Custom GraphQL queries and mutations extend the API beyond auto-generated CRUD for bespoke business logic. The Admin UI built with Next.js and the Keystar UI component library supports custom pages, branded navigation, and internationalized interfaces. OpenTelemetry tracing provides observability into operations, queries, and hook execution. Deploys via Docker or any Node.js host with Prisma managing schema evolution. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
