Eleken vs Spline: Which Is Better in 2026?

Eleken is a UI/UX design agency that specializes in SaaS and software products, offering ongoing product design through a simple subscription model. Instead of one-off projects or the overhead of hiring in-house, you get dedicated designers who work as an extension of your team, handling everything from interface design and design systems to improving usability and the overall experience of your product. By focusing specifically on SaaS, Eleken brings relevant expertise to the particular challenges of designing software that users navigate every day.

Its strengths are SaaS specialization, a dedicated team and a flexible subscription approach. Because they concentrate on software products, Eleken's designers understand the realities of complex interfaces, user flows and design systems that real applications require, rather than treating every project like a brochure site. The subscription model gives you predictable access to ongoing design work without the cost and commitment of full-time hires, which suits the continuous, iterative nature of building and improving a SaaS product. For founders and product teams, that combination of expertise and flexibility is genuinely useful.

Eleken is a great fit for SaaS startups, software companies and product teams that need ongoing, high-quality UI/UX design but do not want to hire in-house or manage one-off projects. It sits alongside other product-design studios in the design-services space, distinguished by its SaaS focus and subscription model. If you are building or improving a software product and want dedicated, experienced product designers working with you continuously and predictably, Eleken is a capable design partner worth considering to make your product look and work its best.

Spline is a design tool that brings 3D and interactivity to the web in a way that's approachable for ordinary designers rather than just specialists. Traditionally, creating 3D graphics required complex, intimidating software and deep technical knowledge, which kept three-dimensional visuals out of reach for most product and web designers. Spline changes that by offering a browser-based, collaborative environment where you can model, animate, and add interactivity to 3D scenes with a friendliness closer to a modern 2D design tool — opening up a whole dimension of creative expression to people who would never have touched traditional 3D software.

With Spline you can create 3D objects and scenes, apply materials and lighting, animate elements, and — crucially — make them interactive, responding to clicks, hovers, scroll, and other events. The results can be exported and embedded directly into websites and apps, so the 3D you design becomes a living part of a real interface rather than a static render. It supports real-time collaboration so teams can build scenes together, and it continues to add capabilities, including AI-assisted creation, that lower the barrier even further. The emphasis throughout is on making 3D feel like a natural extension of design work instead of a separate, arcane discipline.

Spline is used by web and product designers, creative developers, and brands that want to stand out with engaging, modern visuals — interactive 3D heroes, animated product showcases, playful UI elements, and immersive landing pages. As websites increasingly compete on experience and distinctiveness, the ability to add tasteful interactive 3D is a real differentiator, and Spline makes it attainable without a specialist or a steep learning curve. For designers who want to push beyond flat layouts and create something that feels dynamic and memorable, Spline provides a uniquely accessible gateway into 3D, turning what used to be an expert-only capability into a creative tool that a much wider range of people can actually use and enjoy.
