Open-Source & Self-Hosted Alternatives to Contentful & Sanity Headless CMS
Proprietary headless CMS providers that lock content schemas behind expensive tier paywalls and API call quotas.
Why Migrate Away from Contentful & Sanity Headless CMS?
Commercial headless CMS platforms monetize by limiting your content models, localization locales, and API request quotas. Self-hosting an open-source headless CMS like Strapi or Directus gives you unlimited content entries, custom database schemas, unrestricted API traffic, and direct SQL access for real-time joins.
