antivibe.dev
A dark, editorial pre-launch waitlist for a design-led agency workflow platform with AI agents.

antivibe.dev is a pre-launch waitlist site for a SaaS platform aimed at web agencies and design-led freelancers. The product promise is one integrated place to research, design, communicate, and deliver client work, with named AI agents carrying context through each stage. The site is a single-page conversion experience, not a full product demo.
Agency workflows are fragmented across research, design, client comms, and delivery. Generic AI tools add speed but rarely preserve process or client-facing polish. The site had to qualify interest, build a waitlist, and communicate product depth without overwhelming detail, while feeling premium to a visually literate audience sceptical of another AI wrapper.
A narrow coal, paper, and smoke palette with no bright brand colour. Instrument Serif handles headlines, agent names, and the footer wordmark; Inter carries body and UI. Generous spacing, glass surfaces, and serif-led type create an editorial, Apple-adjacent dark UI. Feature cards use bespoke inline product mockups rather than stock photography.
Research.
Instrument Serif - DisplayOne platform for agency workflow
Inter - Body & UIA single scroll narrative: hero proposition, waitlist signup above the fold, six-card bento proof, named AI agents, then a monumental footer wordmark. One-field email capture with inline validation, hash deep-linking to #waitlist, and a calm success state. Trust is built through demonstration (pipeline UI, comms feeds, agent roles) rather than claims.
React 19, Vite 6, TypeScript, Tailwind, Framer Motion, Lenis smooth scroll, Three.js point-cloud heading, and canvas-confetti on signup. Splash loader awaits fonts and critical assets; prefers-reduced-motion disables Lenis, blur strips, and long animations. Waitlist posts to a Make.com webhook; SEO includes Organization, WebSite, and SoftwareApplication schema.
Built across breakpoints.
