Sentinel Next.js + Strapi is a production-ready cybersecurity SaaS theme that combines the power of Next.js 16’s App Router with Strapi’s headless CMS. Built for security companies, SaaS platforms, and tech startups, it features a dark-first design language with 13 fully built pages including a blog system, pricing tables, integration showcase, and more.

The theme uses a fetch-based Strapi REST API client with full TypeScript types and automatic fallback to local JSON data files. This means the theme works out of the box without any CMS setup — just run npm install && npm run dev and you have a complete, working site. When you’re ready to connect Strapi, simply add your API URL and token to the environment variables and all content will be pulled from your Strapi instance.

Every page is built as an async React Server Component that fetches data at build time, producing a fully static site that can be deployed to any hosting platform. The architecture is clean and predictable: each data function in src/lib/strapi.ts tries the Strapi API first, then falls back to the corresponding local JSON file, ensuring zero-downtime builds even if the CMS is temporarily unavailable.
