Keystonejs is an open-source Node.js framework for building content-heavy websites and web applications. It combines a GraphQL API, admin UI, and list-based content model, letting developers define schemas in code while non-technical users manage content.
Free open-source software under MIT. Core costs are self-hosted infrastructure: Node.js hosting, PostgreSQL or MongoDB database, file storage, CDN, and email. Optional managed hosting, cloud services, or enterprise support may add subscription or professional-services fees.
Open Source
Keystonejs is strongest when you need a developer-first CMS with a GraphQL API and full control over data models. Its admin UI and auth features accelerate content-driven sites, but it demands more engineering setup than no-code CMS platforms. It is best for JavaScript teams building custom marketing sites, portals, or headless applications. Choose it if extensibility and code-based content modeling matter more than turnkey hosting.
