Cmssy is a hosted, headless-only CMS: it serves the admin and the content API, and your own app renders the site. Page sections are defined in your code and edited visually in the admin.
Content - pages, data models and records, media, forms, i18n, draft preview, version history and editorial workflow.
Commerce - products with variants and inventory, carts, checkout, orders, discounts, refunds, fulfillment and customer accounts. Payments stay with your provider; Cmssy records the outcome.
APIs - GraphQL delivery API, webhooks, CLI and TypeScript types.
AI agents - an MCP server with 90+ tools and an in-admin assistant (bring your own key). Refunds, cancellations and page deletes wait for your confirmation.
