What is an interactive website?
An interactive website responds to the visitor. Instead of a column of text and stock photos, the page reacts: a product turns as you scroll, a scene shifts with your cursor, a headline assembles itself, a section pins in place while a story plays through it. The visitor stops reading at the page and starts exploring it.
That matters because attention is the scarce thing. A good interactive website design gives people a reason to keep scrolling, and every extra second they spend is a second they spend with your product. Done badly, it is slow and confusing. Done well, it feels effortless, and that is the part we obsess over.
Interactive does not mean heavy.Every site we ship is tested on a mid-range phone, respects reduced-motion settings and keeps text as real, crawlable HTML so Google can read it.
What we build
3D website designCustom three.js and WebGL scenes, product models, reflective water, particles and camera moves driven by scroll.
Scroll-animated storytellingPinned sections, scrollytelling, image sequences and video that plays as you scroll, the way Apple product pages work.
Interactive product pagesRotate, zoom and recolour a product in the browser. Configurators that let buyers build their own version.
AI-assisted design and buildWe use AI for concepts, 3D models and first-draft code, then hand-finish every detail. Faster timelines, same craft.
Cursor and micro-interactionsMagnetic buttons, custom cursors, hover reveals and sound, the small touches that make a site feel alive.
Redesigns that keep your SEOWe rebuild static sites as interactive ones while keeping your URLs, metadata and rankings intact.

Frequently asked questions
What makes a website interactive?
An interactive website reacts to what the visitor does: scrolling, hovering, clicking or dragging. Common techniques are scroll-driven animation, 3D scenes, cursor effects, pinned storytelling sections and product configurators.
How much does an interactive website cost?
Our projects run from $2,000 for a one-page site or 3D hero to $15,000 for a multi-page site with several 3D scenes or a configurator. Most clients choose the Signature package at $4,500 to $8,000. Estimate your project.
Do interactive websites hurt SEO or speed?
They do not have to. We keep all text as real HTML, lazy-load 3D and video, compress models and test on mid-range phones against Core Web Vitals targets.
How long does it take to build an interactive website?
Two to three weeks for a Spark project, four to six weeks for Signature and six to ten weeks for Flagship, from signed scope to launch.
Which technology do you use?
React, TypeScript, Vite and Tailwind CSS, with three.js and WebGL for 3D. We can also hand over to Webflow or Framer for simpler pages.
Do you work with clients outside the US?
Yes. Scrollhaus is fully remote and works with clients worldwide. Calls are scheduled across time zones and quotes are in US dollars.
