How much does a 3D website (Three.js / Spline) cost in 2026?

You saw an « Apple-style » site with a 3D scene reacting to scroll, and you’re wondering if it’s realistic for your budget. Short answer: a 3D hero scene starts around €1,000, a 3D product configurator rather €3,000 to €8,000, and a full immersive experience beyond. The rest of this article explains what moves the price, and above all, when it’s worth it.

What « a 3D website » actually means (3 levels)

The word « 3D » covers three very different things, and their prices have nothing in common.

1. The 3D hero scene : a 3D object or set in your first section, moving on scroll or following the mouse. The most accessible « wow » effect.

2. The 3D product configurator : your product spinnable in 360°, with options (colours, materials). Ideal for e-commerce or industry.

3. The immersive experience (scrollytelling) : a whole journey told in 3D as you scroll. The most spectacular, and the most expensive.

What it costs, level by level

3D hero scene: from €1,000. One object, one interaction (scroll or hover), HD exports. Timeline: 5 to 10 days.

3D product configurator: €3,000 to €8,000. Modelling, dynamic options, integration on your site. Price rises with the number of variants and material realism.

Immersive experience: €8,000 and up. Several scenes, synchronised scroll animations, custom shaders, a tight performance budget.

What drives the bill up: custom shaders, CMS hookups, the number of product variants, and the performance requirement (60 fps on mobile is earned).

Three.js, Spline or no-code: which to choose

Spline: fast, visual, no code. Perfect for a simple scene delivered quickly, editable by a non-technical team.

Three.js: full control, shaders, performance, custom interactions. The choice when the experience must be unique and hold up under load.

No-code (Webflow + embed): viable to drop a Spline scene into an existing site without touching code.

Simple rule: Spline to go fast, Three.js to go far.

When a 3D site is worth it (and when it isn’t)

3D isn’t an end in itself. It’s worth it when it does a job:

• Demonstrating a complex product (industry, hardware, e-commerce) that photos can’t convey.
• Making an impression before a raise: a site that breathes craft makes the team credible.
• Standing out on a B2B site in a sector where everyone looks alike.

Conversely, if your priority is fast conversion on a simple offer, heavy 3D can hurt. A fast, clear site wins then.

Performance, SEO and mobile: the pitfalls

Badly integrated 3D tanks performance, and therefore SEO. Best practices: load the scene after the text, compress models (meshopt, LOD), provide a static fallback for `prefers-reduced-motion` and low-end mobile, and keep critical content (headings, offer) in plain HTML. Done right, your 3D site stays fast and indexable.
