Spline (https://spline.design/) is a 3D design collaboration software platform that enables users to easily create, iterate, and publish 3D content for multiple platforms directly in the browser. Spline's main value lies in making 3D design accessible and collaborative for designers, developers, and teams, supporting real-time editing and production-ready results without the steep learning curve of traditional 3D tools.
Leveraging browser-based technology, Spline allows users to model, animate, apply textures, and build interactive 3D experiences collaboratively. The platform is designed to simplify the creation of 3D assets for web, product prototypes, AR applications, and other digital experiences. Its real-time collaboration features enable multiple designers to work simultaneously, streamlining feedback and speeding up iteration cycles. This positions Spline as a modern alternative to legacy CAD and 3D modeling tools, with a specific focus on accessibility and team workflows.
What technology enables Spline's 3D collaboration?
Spline stands out by delivering complex 3D design capabilities through a web interface, removing the need for heavyweight desktop installations. The platform supports interactive modeling, animation, and texture editing—all from the browser. Its real-time collaboration and cloud-based workflow allow distributed teams to co-create, review, and publish 3D projects efficiently, making it well-suited for remote or hybrid work environments. Spline also integrates with multiple platforms, supporting embedded 3D experiences across web and mobile applications.
Who uses Spline?
Spline primarily serves designers, developers, product teams, and creative professionals looking to rapidly build and refine 3D assets or interactive experiences. Its user-friendly design appeals to startups, agencies, and businesses investing in digital product design, AR/VR content, and web interactivity. The platform’s collaborative features make it valuable for teams that require iterative feedback and shared editing capabilities.
Who are Spline's competitors?
Spline operates within the broader 3D design and collaboration software market. Notable competitors and alternative platforms include:
- RealityMAX: A 3D collaboration platform for real-time teamwork on complex 3D projects.
- Autodesk: Offers advanced 2D/3D design and collaboration tools, widely used in architecture, engineering, and construction.
- SOLIDWORKS: Provides professional CAD design and collaboration, especially for manufacturing and engineering sectors.
