Common mistakes in the October 2026 CMS selection surge

Architecting for existing data versus new builds

Teams often mistake the architectural requirements of a new project for the needs of a legacy migration. Directus acts as a database-first engine that introspects existing SQL schemas to generate an admin UI and APIs without requiring schema rebuilding. Strapi follows a code-first philosophy where the CMS owns the database and manages migrations through its own schema definitions. This distinction means Strapi works best for greenfield projects where developers define content types from scratch, while Directus provides an ideal layer for wrapping existing PostgreSQL, MySQL, or MS SQL databases. You know the difference between a greenfield project and a legacy migration.

The Directus license requires a commercial license if an organization exceeds five million dollars in annual revenue or fifty employees, whereas Strapi provides an unconditional MIT license regardless of the size of the company. Strapi’s CLI wizard scaffolds a fully functional API in minutes by letting developers pick PostgreSQL or MySQL during setup. Directus offers a more affordable entry point through its Cloud service, which starts around $15 per month, though it provides a less opinionated hosting experience than Strapi Cloud. Strapi manages schema changes in version control to keep deployments predictable and CI/CD pipelines clean.

Performance bottlenecks and scale

Performance bottlenecks at scale represent a common failure in project planning. Directus struggles with complex relations, with documented cases showing 500 items with relations take 1,500ms to load. Loading 400,000 files can take over 45,000ms. In contrast, Strapi requires significant memory for its admin build process, often needing 2GB of RAM to prevent out-of-memory errors. Developers using Directus on platforms like App Platform or Kubernetes report sporadic permission errors and disconnections when running multiple instances without a shared Redis store. Does a lack of dedicated Redis instances cause these random 403 errors during schema updates?

Sanity provides a different experience by using a schema-as-code approach where developers define content types in JavaScript or TypeScript. Sanity’s real-time synchronization allows multiple editors to work on the same document simultaneously with live cursors. However, Sanity’s pricing relies on a per-seat model, where the Growth tier costs $15 per occupied seat per month and charges for usage overages. Sanity’s Content Lake replication provides near-zero read latency regardless of the deployment region.

Directus supports a wider range of databases including OracleDB, CockroachDB, and MariaDB. Strapi supports PostgreSQL, MySQL, MariaDB, and SQLite. Sanity remains a proprietary SaaS platform that manages the infrastructure for the user. Directus also faces connection pool crashes under load, specifically when handling 200 row inserts.

Permission models and editorial workflows

The decision between a CMS and a data platform often fails during the editorial workflow transition. Strapi builds its value through a massive plugin marketplace with hundreds of community packages for SEO and workflow automation. Directus includes more features in its core, such as Flows for automation and built-in dashboarding, which reduces the need for third-party extensions. Strapi users experienced significant pain during the v4 to v5 migration due to changes in the REST response shape and the replacement of the Entity Service with the Document Service.

Permissions models also create friction for teams with strict security needs. Directus includes filter-based row-level permissions on all tiers, which gives teams advanced control without reaching for a paid plan. Strapi restricts advanced role-based access control and single sign-on to its paid tiers. Sanity provides field-level translations through its document structure, but published and draft states are per-document, not per-locale.

Strapi uses a React-based admin panel, while Directus uses a Vue.js-based interface. Sanity allows developers to customize the editing environment using React components. Strapi manages schema changes in version control, which keeps deployments predictable and CI/CD pipelines clean. Directus applies schema changes instantly through the Admin UI.
