Contentful

Headless content platform enabling teams to create, manage, and deliver content across websites, apps, and digital channels via APIs. Content lives in a structured, channel-agnostic layer, so developers can consume it through REST or GraphQL for any frontend or channel.

Trusted by enterprises such as Atlassian, KFC, Docusign, Audible, Mailchimp, Kraft Heinz, and Notion. Contentful differentiates from traditional CMSs by being API-first and composable, letting teams pair it with any frontend, commerce platform, or third-party service without vendor lock-in. SDKs exist for JavaScript, Swift, and other runtimes.

Key capabilities:

• Content Delivery API and Content Management API for read and write operations
• Content modeling with reusable content types and rich text
• Multi-locale and media management out of the box
• UI Extensions SDK to build custom field editors in the web app
• Integrations with e-commerce, analytics, and headless frontends

Teams use Contentful for marketing sites, product docs, mobile apps, and e-commerce storefronts where content must be reused across channels. Developers integrate via the Delivery API for fetching published content, or the Management API for programmatic content updates, with optional webhooks for build triggers and cache invalidation.
