Ideal for b2b saas, ai tools, plataformas de desenvolvedores, landing pages tech, startups, apis e sdks. AI-ready template. The dark SaaS hero didn't emerge from nowhere — it's the logical endpoint of a decade-long shift away from the friendly, white-space-heavy interfaces that dominated early SaaS. When Stripe went dark in 2018, it signaled that developer tools could look like luxury goods. The rest of the industry followed. Dark backgrounds became shorthand for technical sophistication. Liquid glass is the latest evolution of this lineage. It borrows from Apple's visionOS material language and the frosted-glass experiments that Figma and Linear popularized, but pushes further — introducing refraction, caustics, and fluid distortion that make UI elements feel physically present. The video background underneath isn't decorative; it's structural. It provides the light source that makes the glass effect legible. What makes this pattern distinct from generic glassmorphism is intentionality. The glass isn't slapped on a gradient. It reacts to content beneath it, creating depth hierarchy without relying on drop shadows or borders. It's a post-flat, post-neumorphic approach that finally treats the screen as a volumetric space rather than a stack of cards. - Density: 5/10 — Balanced - Variance: 4/10 — Moderate - Motion: 8/10 — Cinematic - **Style:** Dark SaaS, Liquid Glass, Video Background, Marquee Social Proof - **Keywords:** dark SaaS, liquid glass, video background, hero section, marquee, social proof, green accent, backdrop blur, glass morphism, navbar pill, announcement badge, CTA buttons - **Era:** 2025-2026 SaaS/AI Startup - **Light/Dark:** ✗ None / ✓ Full ## Colors - **Primary** (#87FB89) — Primary accent, CTAs and interactive elements ## Typography - **Display / Hero:** Geist Sans — Weight 700, tight tracking, used for headline impact - **Body:** Geist Sans — Weight 400, 16px/1.6 line-height, max 72ch per line - **UI Labels / Captions:** Geist Sans — 0.875rem, weight 500, slight letter-spacing - **Monospace:** JetBrains Mono — Used for code, metadata, and technical values Scale: - Hero: clamp(2.5rem, 5vw, 4rem) - H1: 2.25rem - H2: 1.5rem - Body: 1rem / 1.6 - Small: 0.875rem ## Layout - **Grid:** CSS Grid primary.
