Spline
3D design tool for the web with real-time collaboration and easy export to web formats.
Overview
Spline is a 3D design tool for the web with real-time collaboration and easy export to web formats. It handles 3d design, web export, interactions, and real-time collab, and it's best suited for designers who want 3d on the web. It has been around since 2020, giving it a 6-year head start in building out integrations and refining the product.
The free plan is free for 2 projects — enough for most people to evaluate whether it fits. It's designed for small teams, striking a balance between simplicity and collaboration features.
Strengths
- Browser-based 3D design — no heavy software install required
- One-click export to web formats (HTML, React, iframes) for production use
- Free for 2 projects — generous enough for most small teams to get real work done
- Includes interactions alongside the core feature set — fewer separate tools needed
Weaknesses
- Free plan exists but key features are locked behind the paid upgrade
- Fewer built-in features means you may need additional tools to cover gaps
- Output quality depends on your design skills — templates only go so far
- Limited team/admin features if your organization eventually scales up
