Strapi is the world's most popular open-source headless CMS, built with Node.js and designed to be fully customizable with a self-hosted or cloud deployment model. Unlike SaaS headless CMS platforms, Strapi gives teams complete ownership of their content API — the schema, endpoints, authentication, and database (PostgreSQL, MySQL, SQLite) are all under the developer's control. It's used by teams who want the flexibility of a headless CMS without vendor lock-in or per-seat pricing. When a Strapi server directly serves a frontend, responses include x-powered-by: Strapi HTTP headers — the primary detection fingerprint. Strapi's REST API endpoints follow predictable /api/ patterns, and the admin panel is typically accessible at /admin. The open-source Community version is free to self-host, with Strapi Cloud managed hosting starting at $29/month.
