bunpav vs Fast3D
bunpav vs Fast3D: 10-second generations vs. a full export range
Fast3D is built for speed and price — generations in roughly 10 seconds, no login required, and subscriptions starting at $10/month. The catch: free-tier output carries a CC BY 4.0 public license. bunpav trades that speed for a wider raw export range and no license restriction, but is still in private beta. Here's the honest breakdown.
quick answers
The short version
Is Fast3D or bunpav faster for iterating on props?
Fast3D, by a wide margin — both its text-to-3D and image-to-3D generation run in roughly 10 seconds, with no login required to start. bunpav hasn't published a comparable generation-speed benchmark.
Can I use Fast3D's free tier in a commercial game?
Not safely — Fast3D's free tier caps you at 1,000 monthly credits, 1 concurrent task, 2 downloads a day, and the output is licensed CC BY 4.0. That's a public, attribution-required license, the same restriction pattern as Meshy's free tier — it rules out confidential or exclusive commercial use without paying.
How does Fast3D's pricing compare to bunpav's credit packs?
Fast3D runs cheap monthly subscriptions: Pro at $10/mo ($7/mo billed yearly, 10,000 credits, PBR textures), Max at $20/mo ($14/mo billed yearly, 30,000 credits), and a custom Max Unlimited tier. bunpav sells prepaid credit packs with no recurring commitment instead — Starter $9/100 credits, Studio $39/550, Pro $89/1,500.
Which one has the wider export range?
Fast3D covers GLB/GLTF, FBX, OBJ/MTL, and STL — close to bunpav's five formats (GLB, FBX, OBJ, USDZ, STL), with the difference being bunpav's USDZ support for Apple AR Quick Look.
side by side
Full comparison
| Dimension | bunpav | Fast3D |
|---|---|---|
| Availability | Private beta, waitlist-gated | Publicly self-serve today, no login required for the free tier |
| Generation speed | Not benchmarked publicly against Fast3D | Text-to-3D and image-to-3D both generate in roughly 10 seconds |
| Texturing | Textured output on every generation | PBR texture generation with seamless tiling and style transfer (Pro tier and above) |
| Rigging | Auto-rig humanoid/creature skeleton in the same generation pass | Not part of the documented feature set |
| Free tier terms | Welcome credits; product still waitlist-gated | 1,000 monthly credits, 1 concurrent task, 2 downloads/day — output is CC BY 4.0 licensed |
| Paid pricing | Prepaid packs: $9/100, $39/550, $89/1,500 credits, no subscription | Pro $10/mo ($7/mo yearly, 10,000 credits), Max $20/mo ($14/mo yearly, 30,000 credits), Max Unlimited (custom) |
| Export formats | GLB, FBX, OBJ, USDZ, STL | GLB/GLTF, FBX, OBJ/MTL, STL — no USDZ |
A real Primitive Lab capture of a quick, simple prop — the class of asset where Fast3D's near-instant generation speed matters most.
where bunpav wins
No public-license trap on the free tier
bunpav's welcome credits don't carry a CC BY 4.0 requirement the way Fast3D's free tier does — a real constraint if the asset needs to stay private or exclusive.
USDZ export for Apple AR
bunpav's five export formats include USDZ for AR Quick Look; Fast3D's documented list (GLB/GLTF, FBX, OBJ/MTL, STL) stops short of it.
where Fast3D wins
It's the fastest tool in the category
Roughly 10-second generations, no login required to try it, and a genuinely usable free tier for prototyping — hard to match while bunpav is still gated behind a waitlist.
Cheap paid tiers with a lot of credits
$10/month for 10,000 credits (or $7/month billed yearly) is aggressive pricing for teams that generate often and don't mind a subscription.
who should pick which
Match the tool to the job
Pick Fast3D if
You need a tool right now, want the fastest possible iteration loop, and either accept CC BY 4.0 output on the free tier or budget for a cheap paid plan.
Join the bunpav waitlist if
You want USDZ export for AR alongside game formats, prefer prepaid credits over a subscription, and can wait on beta access without a license restriction attached.
faq
Questions, answered
What's the main trade-off between Fast3D and bunpav?
Fast3D optimizes for raw speed and price — roughly 10-second generations, a no-login free tier, and subscriptions starting at $10/month. bunpav optimizes for a wider raw export range and auto-rig in the same pass, with no CC BY 4.0 restriction to navigate, but is still in private beta.
Is Fast3D's free tier good enough for a real game?
Only for prototyping. Free-tier output on Fast3D is CC BY 4.0 licensed — publicly attributed and not exclusive — which most commercial games can't ship with as final assets without upgrading to a paid tier.
Does bunpav generate as fast as Fast3D's ~10 seconds?
There's no independent benchmark comparing the two directly. Fast3D specifically advertises ~10-second generation for both text-to-3D and image-to-3D; bunpav hasn't published a comparable public speed claim.
Which is cheaper for a solo indie dev generating steadily?
If your usage is steady and monthly, Fast3D's Pro tier ($10/mo, or $7/mo billed yearly, for 10,000 credits) is very aggressive pricing. If your usage is bursty — a jam weekend, then nothing for two months — bunpav's prepaid packs avoid paying for idle months.
Can I sign up for bunpav today the way I can with Fast3D?
Not yet. bunpav is in private beta behind a waitlist at bunpav.com. Fast3D requires no login at all for its free tier — that's a real, current gap worth knowing before you plan a project timeline around bunpav.
