Spline — Browser-based 3D design from $12 a month — where the free tier’s watermark on web exports, not the credit count, is what forces the upgrade.
Short answer: Spline is a browser-based 3D design tool. Free provides limited personal files, unlimited file viewers, web exports with a watermark and library access. Hobby is $12 a month billed annually, or $15 monthly, with 2,000 monthly credits, unlimited 3D and 2D files and no watermark. Pro is $25 annually, or $30 monthly, with 3,000 credits, video export and app exports. Max is $60 annually, or $70 monthly, with 10,000 credits plus 10,000 AI credits.

Verdict at a glance
Overall rating: 4.0/5 ★★★★☆
Standout: Real 3D design in a browser with no installation. Spline makes interactive 3D accessible to designers who would never open a traditional 3D application.
Watch out: Free web exports carry a watermark, so anything client-facing needs Hobby at $12 regardless of how few credits you consume.
Spline brings interactive 3D design into the browser, and its real achievement is accessibility — it makes 3D usable by designers who would never open Blender or Cinema 4D, and outputs work that runs on the web rather than requiring a render pipeline. For product pages, landing pages and interfaces wanting depth beyond flat layouts, that combination is genuinely enabling. The free tier provides limited personal files, unlimited file viewers, web exports and access to the Spline Library, but exports carry a watermark. Hobby is $12 a month billed annually, or $15 monthly, providing 2,000 monthly credits, unlimited 3D and 2D files, video upload, higher-resolution image exports, material and audio library access and — the decisive part — no watermark on web exports. Pro is $25 annually, or $30 monthly, with 3,000 credits, unlimited folders and projects, video export, unlimited scenes per file, Apple and Android app exports and no watermark on web embeds. Max is $60 annually, or $70 monthly, with 10,000 monthly credits plus 10,000 AI credits, enhanced media generation five times weekly and higher tool call limits. The watermark is what actually determines your entry point: any client-facing work needs Hobby regardless of credit consumption.

Overview
Spline is a 3D design tool that runs entirely in the browser, and its significance is accessibility rather than raw capability. Traditional 3D software demands a substantial learning investment before producing anything useful; Spline lets a designer who works in flat interfaces produce interactive 3D that ships to the web. For product pages, landing pages and interfaces wanting depth, that lowers the barrier from months of learning to an afternoon.
The free tier provides limited personal files, unlimited file viewers, web exports and access to the Spline Library — but exports carry a watermark. Hobby is $12 a month billed annually, or $15 monthly, and provides 2,000 monthly credits, unlimited 3D and 2D files, video upload, no watermark on web exports, higher-resolution image exports and access to the material and audio library. Pro is $25 annually, or $30 monthly, with 3,000 credits, unlimited folders and projects, video export, unlimited scenes per file, Apple and Android app exports, audio upload, unlimited variables, APIs and webhooks, and no watermark on web embeds. Max is $60 annually, or $70 monthly, with 10,000 monthly credits plus 10,000 AI credits included, enhanced media generation five times per week, 100MB maximum video size and higher tool call limits. Enterprise is custom, adding centralised billing, multi-team support, SAML SSO, code exports, version history and priority support.
The variable that actually determines your entry point is the watermark rather than the credit allowance. Free-tier web exports are watermarked, so any client-facing or commercial work requires Hobby at $12 regardless of how few credits you consume — a designer producing one 3D element a month still needs to pay if that element appears on a live site. Above that, credits and export formats drive the tiers: Pro’s video export and Apple and Android app exports are the reasons to move from Hobby, and Max’s 10,000 AI credits are the reason to move again. Unlimited file viewers on every plan including free is a sensible touch, since stakeholders reviewing 3D work cost nothing.

⚠️ The watermark on free-tier web exports is what determines your entry point, not the credit allowance. Any client-facing or commercial work requires Hobby at $12 regardless of how little you produce — a designer shipping one 3D element a month still pays if it appears on a live site.
⭐ Unlimited file viewers are included on every plan including free, so stakeholders reviewing 3D work cost nothing. That is the same sensible decision Sketch makes, and it matters because reviewers usually outnumber creators considerably.
Above Hobby, export capability drives the tiers rather than credits: Pro’s video export and Apple and Android app exports are the reason to move up, and Max’s 10,000 AI credits alongside 10,000 monthly credits are the reason to move again.

Who it’s for
- Designers adding interactive 3D to web interfaces
- Teams producing product or landing pages wanting visual depth
- Anyone who wants 3D without learning a traditional 3D application
- Developers needing app exports for Apple and Android, at Pro
Who it’s not for
- Studios doing complex 3D modelling — a full suite is the right tool
- Anyone expecting free exports to be usable commercially
- Interface designers who need flat design tools — Penpot or Sketch
- Teams needing whiteboarding rather than 3D — that is Miro
Best use cases
- Adding an interactive 3D element to a product landing page
- Exporting clean, unwatermarked web 3D from the $12 Hobby tier
- Producing video exports of a 3D scene on Pro
- Building Apple and Android app exports from Pro
- Using 10,000 AI credits for generative 3D work on Max
Integrations
Spline exports to the web natively, which is the integration that matters — 3D that runs in a browser rather than requiring a render pipeline is the entire proposition. Pro adds unlimited variables, APIs and webhooks for driving scenes programmatically, and Apple and Android app exports for native targets, while Enterprise adds code exports. The export format you need therefore determines your tier more than credit consumption does.

Alternatives
Nothing else in this comparison does 3D — Penpot and Sketch are flat interface design tools, Miro is a whiteboard and Uizard generates interfaces with AI. Spline’s real alternatives are traditional 3D suites, which are far more capable and far harder to learn. For web-destined interactive 3D, it occupies its category largely alone.

Frequently asked questions
How much does Spline cost?
Free provides limited personal files with watermarked web exports. Hobby is $12 a month annually or $15 monthly with 2,000 credits and no watermark. Pro is $25 annually or $30 monthly with 3,000 credits and app exports. Max is $60 annually or $70 monthly with 10,000 credits plus 10,000 AI credits.
What forces an upgrade from Spline’s free tier?
The watermark on web exports, not the credit allowance. Any client-facing or commercial work needs Hobby at $12 regardless of how little you produce — a designer shipping a single 3D element a month still pays if that element appears on a live site. Credits matter only above that point.
When do I need Spline Pro rather than Hobby?
When you need video export, Apple and Android app exports, unlimited scenes per file, or unlimited variables, APIs and webhooks. Pro’s 3,000 credits against Hobby’s 2,000 is a modest increase — the export formats are the actual reason to move from $12 to $25.
What are Spline’s AI credits?
A separate allowance from monthly credits, included at 10,000 on the Max tier alongside 10,000 monthly credits, with custom amounts at Enterprise. Max also adds enhanced media generation five times weekly and higher tool call limits, so AI capability is the main reason to reach $60 a month.
Does Spline charge for people who only view 3D work?
No — unlimited file viewers are included on every plan including free. That matters because stakeholders reviewing 3D outnumber the people creating it in most organisations, and it mirrors the sensible decision Sketch makes with unlimited free viewers on its subscriptions.
Is Spline a replacement for traditional 3D software?
No, and it does not try to be. Complex modelling work belongs in a full 3D suite. Spline’s achievement is making interactive 3D that ships to the web accessible to designers who work in flat interfaces — a much narrower job, done well, in a browser with no installation.
Spline or Penpot?
They do entirely different things. Penpot is open-source interface design and prototyping, free for eight team members. Spline is browser-based 3D for the web. A team building a product would plausibly use both, with Penpot for the interface and Spline for any three-dimensional elements within it.
