Spline

Overview

Spline is a 3D design tool that runs entirely in the browser, built for designers who want to add depth and interactivity to the web without learning a heavy 3D suite. Where tools like Blender target film and games, Spline targets product and web design: hero visuals, animated icons, interactive backgrounds and playful product showcases. It lowers the barrier to 3D so a UI designer can model a scene, animate it and ship it in an afternoon.

The appeal for a studio like BeBranded is that Spline sits between design and code. You build the scene visually, then hand off a lightweight embed or a component that a developer drops into the page, so 3D stops being a specialist silo and becomes part of the normal design workflow.

How it works

You start from a blank scene and add primitives (cubes, spheres, planes) or import models, then shape them with familiar controls for position, material, lighting and camera. Because it is web native, collaboration works like a shared document: several people can edit the same scene in real time. Interactions are set up with an events system, so an object can react to hover, click or scroll without a single line of code.

When the scene is ready you export. Options include a public embed link, React or vanilla code, a video, or a flat image. For a Webflow or custom site you usually paste the embed or the generated code, and Spline streams the 3D runtime so visitors see the interactive scene in their browser.

Key features

• Browser based 3D editor: model, texture and light scenes with no install.
• Real time collaboration: multiple designers edit one scene together.
• Interactions and events: hover, click, scroll and drag behaviours without code.
• Animation timeline: keyframe movement, materials and cameras.
• Flexible export: embed link, React or vanilla code, video or image.
• AI and physics helpers: generate textures and add basic physics to objects.

Use cases

Spline shines on hero sections that need to feel alive, on product pages that show an object the visitor can rotate, and on landing pages where a subtle 3D background raises perceived quality. Agencies use it to differentiate a client site from flat template competitors. Product teams use it for onboarding illustrations and animated mascots. It is also a strong tool for pitches and mockups, because an interactive scene communicates a concept faster than a static slide.

In a BeBranded engagement, Spline typically adds one signature interactive moment to a Webflow build, a detail that makes the site memorable without a full custom WebGL project.

Pros

• Very approachable: designers reach usable 3D far faster than with traditional suites.
• No code interactions that map cleanly onto web behaviours like scroll and hover.
• Real time collaboration that fits modern design teams.
• Multiple export paths so the same scene serves web, video and images.
• Strong for differentiation: 3D still feels premium on most marketing sites.

Cons

Spline is powerful but it is not free of trade offs. The biggest is performance: 3D scenes are heavier than images, and a complex Spline embed can hurt load time and Core Web Vitals if you are not careful, especially on mobile and low end devices. You have to budget for that and optimise, or the wow factor costs you conversions. The tool is also less deep than dedicated 3D software, so advanced modelling, precise topology or film grade rendering are out of scope. There is still a learning curve around materials, lighting and the events system, and results can look amateurish without design taste. Pricing moves to a subscription once you need private projects and higher export limits, and heavy reliance on the hosted runtime means your scene depends on Spline staying available. Used deliberately, on one or two focal elements rather than everywhere, it is an excellent way to make a site stand out.
