## 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.
