The official also states that it provides an AI design agent (3D Design Agent) and an interactive design canvas called Hana, which help transform ideas directly into deliverable 3D experiences. For teams working on web pages and product displays, it brings 3D production capabilities to the browser.
Who is it for?
- Web designers and front-end developers building interactive official websites and product displays who want lightweight 3D experiences.
- Brand and product teams that need to create 3D logos, 3D icons, and 3D mockups for a unified visual identity.
- Creators of gamified experiences and animated characters for rapid prototyping.
- Teams engaged in industrial and manufacturing visualization and brand marketing 3D content creation, building illustrative scenes.

How to use Spline
- 1Start with community templates called "remix" to understand interaction and material settings faster than from a blank scene, avoiding detours.
- 2For real-time collaboration, pay attention to accounts and permissions. For team projects, define the version and sharing scope in advance to avoid conflicts.
- 3The browser version has performance limits for complex scenes; for heavy scenes, export them as separate modules and then combine them to ensure smoothness.
- 4Pay attention to the scope of authorization when referencing models and materials; for commercial use, it shall be subject to the official instructions, and paid assets need to be confirmed.
- 5Official features and quotas may be adjusted. Check the current terms again before official use to confirm coverage of entitlements.
