Payload CMS
Exact Definition
Payload CMS is an open-source, TypeScript-native headless CMS built on Next.js that provides a fully customizable admin UI, flexible collection schemas, and API-first content delivery — without the per-seat pricing of Contentful or the plugin complexity of WordPress.
Architectural Deep Dive
Unlike WordPress (PHP-based, plugin-dependent) or Contentful (SaaS, per-seat pricing), Payload CMS is a code-first, TypeScript-native system where the content schema is defined as JavaScript objects. This means the CMS configuration lives in your version control, migrations are code-reviewed, and the entire system is self-hosted with zero recurring licensing fees. Payload generates a production-ready admin UI, REST API, and GraphQL API automatically from your schema definitions.
The ERPStack Approach
We implement Payload CMS for clients replacing WordPress or Contentful, hosting it within their existing Next.js application on Vercel — eliminating CMS subscription fees and providing complete content model ownership.
