Frequently Asked Questions
Should I choose Strapi or Payload CMS in 2026?
Choose Strapi (`strapi/strapi`, 65.2k stars) when you want a mature visual admin UI, a rich community plugin marketplace, and standalone server separation for non-technical content editors. Choose Payload CMS (`payloadcms/payload`, 28.5k stars, 100% MIT) when building modern Next.js/React applications where you want your CMS to live directly inside your Next.js project with zero extra servers, automatic TypeScript types, and direct database queries.
How do Strapi and Payload eliminate $2,500+/month Contentful and Sanity bills?
Commercial headless CMS platforms like Contentful ($1,995-$4,995/month) and Sanity.io ($949+/month) charge aggressive fees based on user seats, content record limits, API request counts, and asset bandwidth. Deploying open-source Strapi or Payload CMS on standard cloud instances or serverless edge hosts handles 1M+ monthly API calls and unlimited content records for ~$145/month (-94.2%) with zero asset bandwidth taxes.
