Spline
3D design tool in the browser with real-time collaboration
Spline is a browser-based 3D design platform for building real-time interactive experiences, combining 3D modeling, animation, materials, and interactivity with an AI agent that works alongside the designer. It also includes Hana, a collaborative 2D canvas for interactive interfaces and motion, and supports shipping experiences to the web, iOS, and Android through integrations with Webflow, Framer, Wix Studio, HTML/JS, React, Next.js, Swift, and Kotlin.
Key capabilities include real-time rendering, primitives and 3D modeling, layer-based materials, states and events, timeline animation, physics and particles, and variables, webhooks, and APIs for real-time data. The 2D editor offers an infinite canvas, frames and auto layout, vector networks, visual effects, and AI-assisted image generation, background removal, and upscaling. Security features include TOTP verification, optional SAML SSO and 2FA for enterprises, encryption in transit and at rest, multi-region backups, and SOC 2 and ISO 27001 certifications.
Spline is available as a free plan with limited personal files, watermarked web exports, and access to the library. Paid editions—Hobby, Pro, and Max—are priced per seat, with monthly credit allowances that scale by plan and optional credit add-ons. Enterprise offers custom pricing, centralized licensing, SAML SSO, code and self-hosted exports, team libraries, file version history, and priority support, with a trial available on request.
