Prismic
Prismic is a headless content management system with developer tools and a visual page builder for websites built on an existing stack. Its Visual Page Builder supports live editing, drag-and-drop layouts and reusable slices; Slice Machine helps model content and generate TypeScript and component structure. Official integrations and SDKs are listed for Next.js, Nuxt and SvelteKit. Teams can localize content, configure custom roles, preview pages, review revision history and roll back changes. Imgix integration optimizes images, and each page includes schema support. APIs, webhooks and a Migration API support integrations and structured content migrations. Prismic runs as a single product across web and API platforms and connects to Claude, ChatGPT and other MCP-enabled AI tools. The free plan allows one user, two locales and 4 million API calls monthly; it includes 100 GB of monthly CDN bandwidth, and exceeding that allowance locks the project. Paid plans start at $10/mo (annual). Prismic was founded in 2013 and is headquartered in Paris, France.
