Headless CMS comparison

A headless CMS manages content without imposing a presentation layer. It exposes data through APIs (REST or GraphQL) so any frontend can consume it: web, mobile app, kiosk or voice assistant. Compared to a traditional CMS like WordPress, the advantage is twofold: total frontend freedom and content reuse across multiple channels.

Headless CMS adoption has grown exponentially since 2022. Teams that once relied on rigid templates now build interfaces with React, Astro or Vue while editors manage content in an intuitive, decoupled panel.

Strapi is the most popular open-source headless CMS. It installs on your own infrastructure (or on Strapi Cloud) and provides an admin panel automatically generated from your data model. It supports REST and GraphQL, has a granular role system and an active community with hundreds of plugins.

Its main advantage is total control: you do not depend on a third party to host your data and are not subject to usage limits. The trade-off is the responsibility of maintaining infrastructure and updates. Ideal for technical teams that want maximum flexibility without vendor lock-in.

Contentful was one of the first headless CMS platforms on the market and remains a reference in the enterprise segment. It is a fully managed SaaS: there is no infrastructure to manage, and its global CDN guarantees low latency in any region. It stands out for its content modelling system, environment management (staging, production) and native integrations with tools like Vercel, Netlify and Gatsby.

The weak point is pricing: the free plan is very limited (25,000 records, 2 locales) and paid plans scale quickly. For small projects it can be expensive; for large organisations with governance and multi-language needs, it is one of the most robust options available.

Sanity stands out for its real-time data model and its portable WYSIWYG editor (Portable Text) that stores content as structured data. Its studio is fully customisable with React, enabling bespoke editorial experiences. Pricing is usage-based (API calls, datasets, users) with a generous free tier for small projects.

Directus is an open-source headless CMS that connects to any existing SQL database (PostgreSQL, MySQL, SQLite, MariaDB). It does not create its own schema: it generates an API layer and admin panel on top of your database. It is ideal when you already have data in a relational DB and want to expose it as an API without migration. Its approach is pragmatic and backend-developer oriented.

There is no universally superior headless CMS. The choice depends on factors such as team profile, editorial requirements, budget and project scale. A technical team that wants total control and no vendor lock-in will gravitate towards Strapi or Directus. An enterprise organisation that needs SLA, support and governance will prefer Contentful or Sanity.

Other relevant factors include localisation support (multi-language), documentation quality, community size and ease of integration with your frontend stack. Before deciding, build a prototype with two or three options and evaluate the real development and editing experience.

Strapi is free when self-hosted; Strapi Cloud starts at $29/month. Contentful has a limited free tier and its Team plan costs $300/month. Sanity charges by usage (API calls, bandwidth, users) with a generous free tier. Directus is free self-hosted, with Directus Cloud from $15/month.

For scalability, Contentful and Sanity manage infrastructure for you and scale automatically. Strapi and Directus require you to size and manage your own servers, although both run perfectly on platforms like Railway, Render or AWS. The key is to project total cost over 12–24 months, including infrastructure, development hours and support.
