Sentinel for React is a premium cybersecurity SaaS theme built from the ground up with Vite, React 19, and Tailwind CSS v4. Designed dark-first with a cyan/violet color palette, geometric aesthetics, and glassmorphism effects, it delivers the polished look that enterprise security products demand — while being fully adaptable to any SaaS niche.

What’s Included

Sentinel ships with 13 production-ready pages: Home, About, Features, Pricing, Blog (listing + individual posts), Contact, Integrations, Reviews, Changelog, Elements (UI kit), Privacy Policy, Terms of Service, and a custom 404 page. Every page is fully responsive across mobile, tablet, and desktop breakpoints with intentional dark and light mode designs — not an afterthought toggle, but two carefully crafted visual experiences.

The theme features hand-crafted SVG dashboard mockups throughout — a full cybersecurity dashboard in the hero section and six unique feature illustration variants (data vault, identity management, incident response, compliance dashboard, threat intelligence, and API security gateway). These are inline SVGs that adapt to the theme’s color system and dark/light modes automatically, with zero external image dependencies.

Built with Modern React

Sentinel uses Vite for blazing-fast development and builds, React 19 for the latest React features, and React Router for seamless client-side navigation. The theme is a single-page application (SPA) that can be deployed to any static host — Netlify, Vercel, GitHub Pages, or any CDN. Blog posts are loaded from Markdown files using Vite’s import.meta.glob with a custom lightweight frontmatter parser and markdown renderer — no Node.js dependencies in the browser.

Developer-Friendly Customization

All content is externalized into JSON data files — swap out the company name, navigation links, features, pricing tiers, team members, testimonials, FAQ items, integrations, and changelog entries without touching component code. A single site-config.json controls the site identity, social links, and footer content. The design system is defined entirely in CSS custom properties within index.css, making color and typography changes a single-file edit.

SEO and Performance

Every page updates the document title and meta description dynamically via a custom useMeta hook. The theme ships with Open Graph meta tags in the HTML entry point. Built with Vite for optimized production bundles with automatic code splitting and tree shaking.
