Sentinel React Sanity is a professionally crafted cybersecurity SaaS theme that combines the power of React 19, Tailwind CSS v4, and Sanity CMS. Designed for security companies, SaaS startups, and tech businesses that need a modern, content-managed web presence.

Built as a headless CMS variant of the popular Sentinel theme, this version replaces static JSON files with Sanity GROQ queries while maintaining a seamless fallback system. The theme works out of the box without any CMS configuration — simply run npm install && npm run dev and all pages render with built-in fallback data. When you’re ready, connect your Sanity project and manage content through the Sanity Studio.

The theme ships with 14 fully designed pages including a homepage with hero, social proof, feature showcase, pricing tables, testimonials, and CTA sections. The blog system supports both local markdown files and Sanity Portable Text, giving you flexibility in how you manage content. Every component is built with TypeScript, follows accessibility best practices, and is optimized for performance with Lighthouse scores above 90.

With a dark-first design system, custom font loading (Space Grotesk + Inter), and a comprehensive Tailwind CSS v4 token system, Sentinel React Sanity delivers a premium look that’s easy to customize. The complete Sanity schema documentation is included in the README, making setup straightforward for developers of any experience level.
