bunpav vs Spline AI
bunpav vs Spline AI: game-ready meshes vs. interactive web 3D
Spline AI is an add-on subscription stacked on top of Spline's core interactive 3D web-design platform — you need two separate subscriptions before you can generate anything. bunpav is a standalone prompt-or-photo-to-mesh generator with one credit pool, built for game-engine export rather than interactive web scenes, but is still in private beta. Here's the honest breakdown.
quick answers
The short version
Is Spline AI a standalone 3D generator like bunpav?
No. Spline AI (Generate) is an add-on feature bolted onto Spline's core interactive 3D web-design platform — you need an active Spline Professional or Team plan before the AI add-on even applies. bunpav is a standalone prompt-or-photo-to-mesh generator with a single credit pool.
How many subscriptions does Spline AI actually require?
Two, stacked. A Spline plan (Starter $12/mo or Professional $20/mo, both billed yearly) to use the platform at all, plus a separate Spline AI add-on at $5/seat/month for 2,000 AI credits. bunpav's model is one subscription-free credit pool covering both text-to-3D and image-to-3D.
What is Spline actually good at that bunpav isn't?
Real-time interactive 3D scenes for the web, AR, and mobile — Swift code snippets for iOS, Kotlin/APK/AAB for Android, and embeddable web scenes. That's a fundamentally different use case than bunpav's GLB/FBX export pipeline aimed at game engines.
Which one can I actually sign up for right now?
Spline AI — it's publicly self-serve, assuming you're willing to pay for both the base Spline plan and the AI add-on. bunpav is currently in private beta behind a waitlist.
side by side
Full comparison
| Dimension | bunpav | Spline AI |
|---|---|---|
| Availability | Private beta, waitlist-gated | Publicly self-serve today, requires paid Spline plan |
| Core use case | Game-ready meshes for engine import (GLB, FBX, OBJ, USDZ, STL) | Interactive 3D scenes for the web, AR, and mobile apps |
| Subscription structure | One credit pool, no base platform subscription required | Two stacked subscriptions: base Spline plan + separate AI add-on |
| Paid pricing | Prepaid packs: $9/100, $39/550, $89/1,500 credits, no subscription | Starter $12/mo or Professional $20/mo (billed yearly) + AI add-on $5/seat/mo for 2,000 credits |
| Generation modes | Text-to-3D and image-to-3D, auto-rig in the same pass | Text-to-3D, image-to-3D, AI texture generation, AI style transfer, 4 variants per prompt |
| Rigging | Auto-rig humanoid/creature skeleton included in generation | Not a core feature — Spline is built for scene interactivity, not character rigging |
| Export/embed targets | GLB, FBX, OBJ, USDZ, STL files for engine import | Swift (iOS), Kotlin/APK/AAB (Android), embeddable web scenes |
A real Primitive Lab capture of a static, exportable mesh review — a genuinely different output than Spline AI's real-time interactive web scenes.
where bunpav wins
One credit pool, no stacked subscriptions
bunpav doesn't require a separate base-platform plan before its generation credits even apply. Spline AI needs an active Professional or Team Spline plan plus its own add-on subscription on top.
Built for game-engine export from the start
GLB, FBX, OBJ, USDZ, and STL target engine import and 3D printing directly, plus auto-rig in the same pass — Spline AI's outputs are optimized for interactive web scenes, not game-ready character pipelines.
where Spline AI wins
Real-time interactive web/AR/mobile export
Swift code snippets for iOS, Kotlin/APK/AAB for Android, and embeddable web scenes are Spline's core competency — a genuinely different and valuable use case than static game-engine meshes.
You can use it right now
Spline AI is publicly self-serve today, assuming you're willing to pay for both the base plan and the add-on. bunpav is still gated behind a private-beta waitlist.
who should pick which
Match the tool to the job
Pick Spline AI if
You're already building interactive 3D scenes for the web, AR, or mobile in Spline, and generating quick 3D assets to drop into that same interactive scene is more valuable to you than a static game-engine mesh.
Join the bunpav waitlist if
You need game-ready meshes with auto-rig for Unity, Unreal, or another engine, want one credit pool instead of two stacked subscriptions, and can wait on beta access.
faq
Questions, answered
What is the main difference between Spline AI and bunpav?
Spline AI is an add-on feature inside Spline's interactive 3D web-design platform, aimed at real-time web, AR, and mobile scenes — it requires a base Spline subscription plus a separate AI add-on. bunpav is a standalone generator focused on game-ready meshes with auto-rig, using one credit pool and no base-platform subscription, but is still in private beta.
Do I need to already be a Spline user to use Spline AI?
Yes. Spline AI (Generate) only works with an active Professional or Team Spline plan — it's not sold as a standalone product. That's a real cost and workflow gate to know about before comparing it head-to-head against a standalone tool like bunpav.
How much does Spline AI actually cost all-in?
At minimum, a Starter Spline plan ($12/mo billed yearly) plus the AI add-on ($5/seat/month for 2,000 credits) — two line items stacked together. Check Spline's current pricing page directly, since add-on terms and credit allotments can change.
Can I use Spline AI output in a game engine like Unity or Unreal?
Spline is built around real-time interactive scenes for the web and mobile apps (Swift, Kotlin/APK/AAB, embeddable web scenes) rather than static GLB/FBX exports for game engines. If your target is a game-engine pipeline specifically, that's a different use case than what Spline AI is optimized for — check Spline's current export options before assuming engine compatibility.
Which is better for a solo indie dev building a game, not a website?
If your deliverable is game-engine-ready character and prop meshes, bunpav's focus (auto-rig, GLB/FBX/OBJ/USDZ/STL export) is the closer fit conceptually, though it's still in private beta. If your deliverable is an interactive 3D web experience or AR app, Spline AI's stack is purpose-built for that instead.
