How to choose for the same task
Both sides belong to the 3D Generation category. The conditionals below come from this site's directory records: first check which side's suitability fits your task and which side's exclusions affect you less; if both fit, decide by pricing basis and by how well platforms and formats line up. Prices appear only where a record has been verified; where it has not, no number is given.
Spline AI
Fact sourceWhen to pick it Choose Spline AI when an interactive 3D scene has to run in the browser and the export set has to include USDZ, STL, or GLTF with colour and texture: on that page those exports, like the Apple and Android exports and code export, need the Pro tier at the lowest (25 USD per seat per month billed yearly, 30 monthly).
When to skip it Free shows a cross in the Included AI Credits row, its file count is Limited Personal Files and web exports carry a watermark; Hobby has 2,000 credits but still no USDZ, STL, colour GLTF, or Apple and Android exports, and self-hosted export and multi-team organisation stop at Enterprise. For parametric templates that output clean-topology game assets, the closer directory record is Sloyd; to pull the weights local and batch-generate assets, the closer record is Microsoft TRELLIS. This is not a ranked review.
Verified price: Free 0 — USD / month; Hobby 12 (billed annually) or 15 (monthly); Pro 25 (billed annually) or 30 (monthly); Max 60 (billed annually) or 70 (monthly) — USD / seat / month; Enterprise Custom Pricing, billed yearly. AI credits: Free not included; Hobby 2,000 / month; Pro 3,000 / month; Max 10,000 / month; Enterprise Custom. (region: not stated, checked 2026-10-12). Annual prices are not converted to monthly.
Official sourceWorld Labs Marble
Fact sourceWhen to pick it Choose Marble when a walkable 3D world is needed for previz or greyboxing and splats or meshes must be exported into an existing pipeline: the Standard tier already gives splat and low-resolution collider mesh export, and Pro gives high-resolution textured meshes.
When to skip it Commercial rights appear only on the Pro tier and above, not on the Free and Standard feature lists, and high-resolution textured mesh export likewise starts at Pro while Standard keeps low-resolution collider meshes. For measurement and floor plans from scanned real spaces, the closer directory record is Polycam; for single-camera markerless mocap from one phone on a monthly subscription, the closer record is Move AI. This is not a ranked review.
Verified price: Free 0 / month (7,000 credits); Standard 20 / month (20,000); Pro 35 / month (40,000); Max 95 / month (120,000) — USD / month; credit packs 5 USD / 5,000 credits, 20 USD / 22,000, 50 USD / 63,000 (region: not stated, checked 2026-10-12). Annual prices are not converted to monthly.
