    About

    In practice. What you can do with Spline.

    Spline lets teams model, texture and animate 2D and 3D scenes together in the browser, then publish them as interactive content that reacts to clicks, scroll and other input directly on a website. AI-assisted generation can produce textures or assets inside the editor, metered by monthly credits.

    The free plan covers light personal use with a watermark; paid seats start at $12/month billed annually and add unlimited files plus AI credits, with export formats such as iOS, Android, GLTF and USDZ unlocking progressively on higher tiers. Code export and self-hosting are reserved for the custom-quoted Enterprise plan.

    Spline becomes worthwhile when
    • You use it at least once a week
    • The monthly cost ($12) is small next to the time it saves you

    Challenge if

    Spline's billing traps

    Before you pay

    AI credits are a separate metered cost on top of the seat price, and annual billing is required to reach the lowest per-seat rate.

    Our verdict. What to know about Spline.

    Why this verdict

    Average

    Added value

    Paid seats start low ($12/month annually) and bundle real-time collaboration with interactive publishing, but AI credits are metered separately and can add unpredictable extra cost.

    Simplicity

    Neutral score: time and skill needed for a first useful result are not covered by the collected sources.

    Fit for purpose

    The tool delivers its stated promise of real-time collaborative 2D/3D creation and interactive publishing that reacts to user input, without a documented need for third-party tools.

    Performance

    Combines real-time 2D/3D modeling, texturing, animation, interactive publishing and AI-assisted media generation, with export to GLTF, USDZ, STL and native iOS/Android on higher tiers.

    Reversibility

    Code export and self-hosted deployment, the paths that avoid lock-in to Spline's own viewer, are reserved for the custom-quoted Enterprise plan and unavailable on Hobby, Pro or Max.

    The AI angle

    Spline vs AI

    AI augments this tool
    Go further with AI

    Spline added an AI texture and material generator, but remains a collaborative in-browser 3D design tool — 3D modeling and animation remain assisted manual creative work.

    Can AI replace it?

    Replace Spline with an AI? No: modeling and animating an interactive 3D scene with precise design intent remains creative work AI assists (generated textures) without replacing. Verdict: AI augments material creation, 3D modeling remains a human skill.
