Strapi
Open-source headless CMS with full API customization
Overview
Strapi is the most popular open-source headless CMS, giving development teams a content management layer that they fully own and control. Self-host on any infrastructure, customize the API to exact specifications, and provide content editors with an auto-generated admin panel.
The content type builder lets you define your data model visually, and Strapi automatically generates REST and GraphQL APIs, admin UI, and database schemas. This removes the boilerplate of building a content API from scratch while maintaining the flexibility to customize every aspect.
For teams with data sovereignty requirements or specific hosting needs, Strapi's self-hosted model means your content stays on your infrastructure. There is no vendor dependency, no surprise pricing changes, and no platform risk - your CMS is a codebase you own.
