Contentful : everything you need to know about the Headless CMS

by Emmanuel Valluche 28 December 2025

Contentful, created in 2013 and used by over 100,000 digital platforms (with clients such as Spotify, Urban Outfitters, and Red Bull), is a leading decoupled content management platform (also called a headless CMS). It is an effective alternative to traditional CMS’ thanks to its orientation as a “content hub” designed to feed all communication channels of the advertiser (digital platform, mobile application, e-commerce…) via robust and flexible APIs.

With over 22.8k deployed sites and its SaaS orientation, Contentful proves its ability to facilitate the rapid launch of projects, products, and experiences by allowing users to easily build and deploy their own applications without the constraints often associated with traditional content management systems.

Also designed to meet developers’ needs, thanks to its “developer first” approach, Contentful integrates easily with many tools and frameworks. Its platform handles over one billion API calls every day, ensuring consistent performance and availability. Kaliop has worked for many years and was the first French partner of the headless CMS Contentful.

    A composable content platform serving agile organizations

    Contentful is a composable content platform integrated into a composable or service-oriented application architecture.

    Indeed, this vision of “composable” applies at several levels :

    • Targeted “composable content”, Contentful allows fine structuring of the content (a title field, a text field, video, images, languages…) to be exposed, depending on business needs but also the targets and platforms to address.
    • Integrated into a “composable architecture” or service-oriented, Contentful is “API First,” so it is designed to natively exchange with other services organizing modern platforms: e-commerce, PIM, CRM, etc.

    At the heart of this dynamic is the idea of the Digital Factory, which promotes close collaboration between the company’s different functions, relying on flexible and modular systems.

    In this context, Contentful is the content management building block that developers integrate into the composable architecture in the programming language of their choice, while editorial teams benefit from an intuitive interface to add or modify content. This setup allows each team to maintain autonomy while working synchronously, thus avoiding dependency on isolated workflows.

    Contentful vs Strapi

    Though they have much in common (Headless CMS, API-First, content personalization), Strapi and Contentful differ in certain respects :

    • License model : Strapi is Open Source and can be self-hosted, offering full control over the infrastructure. Unlike Contentful, which is SaaS (Software as a Service) with a usage-based pricing model.
    • Infrastructure and hosting : Strapi requires hosting, which involves extra deployment and management effort and cost but offers greater flexibility and control in return. Contentful operates its Cloud platform, reducing infrastructure management load, guaranteeing high availability, enhanced security, and scalability.
    • Community and support : Strapi, as an Open Source project, benefits from an active community that contributes to its development, including community plugins, tutorials, and assistance via various community channels. Contentful offers professional support and consulting services for enterprises, with dedicated support plans.

    In summary, Strapi and Contentful are two CMS’ suited for ambitious service-oriented products/platforms.

    Contentful stands out for its maturity, “business accelerator” positioning, and reliability under high traffic, while Strapi is suitable for teams seeking strong interface or content customization, data localization on the territory of their choice (thus meeting sovereign cloud expectations), and budget control.
