Sentinel for Next.js is a premium cybersecurity SaaS theme built from the ground up with Next.js 16, 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 for Modern Next.js

Sentinel uses Next.js 16’s App Router with React Server Components by default and client components only where interactivity is needed (theme toggle, pricing toggle, mobile menu, integration filters). The theme is configured for static export (output: "export"), making it deployable to any static host — Netlify, Vercel, GitHub Pages, or any CDN. Blog posts are loaded from Markdown files with gray-matter frontmatter parsing and a custom lightweight renderer.

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 globals.css, making color and typography changes a single-file edit.

SEO and Performance

Every page includes unique meta tags via Next.js Metadata API, with Open Graph and Twitter card support. The theme ships with static export for maximum performance and easy deployment. Built as fully static output with no server-side runtime required.
