Spline

Spline is a 3D design platform with sculpting, animation, and parametric modeling tools, plus a built-in render engine. Its features include real-time rendering, AI editing, and motion, and it can export designs for 3D printing. Experiences can be shipped to the web, Apple, and Android. Integrations include Webflow, Framer, Wix Studio, HTML/JS, React, Next.js, Swift, and Kotlin. The free plan costs $0 per month and includes limited personal files, unlimited viewers, watermarked web exports, and Spline Library access. Paid plans add exports and higher-resolution options. Hobby costs $15 a month billed annually and includes 2,000 monthly credits; Pro costs $30 a month billed annually with 3,000 monthly credits; Max costs $70 a month billed annually with 10,000 monthly credits. Enterprise has custom pricing and includes features such as private teams, centralized licensing and billing, SAML single sign-on, priority support, onboarding, and training. Enterprise customers can request a trial. Spline lists ISO 27001 and SOC 2 compliance. Spline, Inc. is headquartered in Middletown, Delaware.

Spline combines 3D creation tools with exports and integrations for several platforms. The free tier has limits, while paid tiers include monthly AI credits and Enterprise adds team and support capabilities.

Spline may suit people creating 3D models or animated experiences for web, Apple, or Android. Its integrations and team features may be relevant to designers and development teams.

Spline is a browser-oriented 3D creation platform for designers and developers building animated, interactive scenes for websites and mobile apps. It is strongest when a project needs modeling, motion, rendering, and developer-oriented exports in one workflow. The free plan is suitable for learning and prototypes, while finished, unwatermarked work generally requires a paid tier.

Overview

Spline brings sculpting, parametric modeling, animation, motion, AI editing, and real-time rendering into one workspace. Its built-in render engine avoids treating rendering as a separate product, and 3D-print export gives the tool a use beyond screen-based experiences. Publishing targets include the Web, Apple platforms, and Android.

The workflow connects to Webflow, Framer, Wix Studio, HTML/JS, React, Next.js, Swift, and Kotlin. That makes Spline a practical bridge between visual 3D design and application delivery rather than an isolated modeling package. Spline, Inc. is headquartered in Middletown, Delaware, United States. The platform lists ISO 27001 and SOC 2 compliance. For a wider category comparison, see our 3D modeling software directory.

Key features

• Modeling: Sculpting supports freeform shaping, while parametric modeling suits geometry that needs controlled adjustments.
• Animation and motion: Animation tools make the same workspace useful for moving scenes and interactive visual content.
• Rendering: Real-time rendering is built in, keeping scene creation and visual output together.
• AI editing: AI capability is tied to monthly credits, so frequent AI work depends on the allowance of the selected plan.
• Exports: Spline supports 3D-print export and deployment to Web, Apple, and Android. Paid plans add exports and higher-resolution options, while free web output carries a watermark.
• Integrations: Connections to visual site builders and code frameworks make it easier to move a scene into a broader product workflow.

Pricing

Spline uses a freemium model. The Free plan costs $0.00 per month and permits limited personal files with unlimited file viewers. Web exports are watermarked, and the free tier includes access to Spline Library; those limits make it better for evaluation, private practice, and early concepts than polished public delivery.

Hobby costs $15.00 per month when billed annually, although the advertised paid entry point is $12/user/mo on an annual term. It includes unlimited 3D and 2D files and 2,000 monthly AI credits. This is the sensible individual upgrade when file limits and watermarks block regular work.

Pro costs $30.00 per month when billed annually and includes 3,000 monthly credits, unlimited folders and projects, unlimited scenes per file, and unlimited Variables, APIs, and Webhooks. It fits developers and production users who need structured projects and deeper integration controls.

Max costs $70.00 per month when billed annually. Its 10,000 monthly AI credits and 100MB maximum video size are aimed at heavier AI usage and larger media output. Each paid plan is priced per seat, so multi-person use scales with the number of users.

Enterprise uses custom pricing and is billed annually. It adds centralized licensing and billing, multiple private teams, SAML Single Sign-On, code and self-hosted exports, file version history, priority support, onboarding, and training. Enterprise customers can request a trial. No refund policy is stated, so buyers should confirm cancellation and refund terms before committing.

Platforms

Spline ships experiences to the Web, Apple, and Android. Its integration list covers Webflow, Framer, Wix Studio, HTML/JS, React, Next.js, Swift, and Kotlin, giving both no-code site builders and application teams a route from scene design to deployment. Enterprise security onboarding includes SAML SSO and legal and security support. General support contact is [email protected].

Who it's for

Spline suits designers creating interactive 3D, developers embedding scenes in web or mobile products, and teams that need visual authoring alongside code-oriented exports. Hobby is appropriate for an individual who needs unlimited files; Pro is better for integration-heavy production work; Max is for users whose AI-credit or video-size needs exceed the lower tiers. Enterprise is the appropriate choice for organizations requiring private teams, centralized administration, SSO, version history, and guided support.

Pros and cons

Pros

• Broad creation stack: Sculpting, parametric modeling, animation, motion, AI editing, and real-time rendering share one workflow.
• Wide delivery reach: Web, Apple, and Android publishing plus integrations with major builders and frameworks support varied products.
• Useful enterprise controls: Private teams, SAML SSO, centralized billing, version history, and priority assistance address organizational needs.
• Free evaluation: Unlimited viewers let stakeholders inspect free-tier work even though exports remain watermarked.

Cons

• Free output is restricted: Limited personal files and watermarked web exports constrain finished public projects.
• AI usage is quota-based: Monthly credits range from 2,000 on Hobby to 10,000 on Max, so intensive AI workflows may require an expensive upgrade.
• Annual billing: Published paid prices apply when billed annually, reducing flexibility for short-term users.
• Enterprise pricing is custom: Organizations cannot assess that tier from a listed public price.

Alternatives

Choose SketchUp instead if you want browser-based modeling with Trimble Connect storage and 3D Warehouse access; its free plan is not for commercial use and it also runs on iOS and Windows.

Onshape is the better fit for cloud CAD collaboration when Android, iOS, and web access matter, though its free plan is non-commercial and makes all documents public.

Pick Meshy instead when a credit-based workflow and model downloads are the priority; its free plan includes 100 credits and 10 free monthly downloads for Meshy 6 Lite models.

Solid Edge is an alternative for users seeking a broader engineering-oriented design package.

uMake is worth considering for iOS and macOS-focused 3D work, with a free tier offering two spaces and watermarked rendering.

Forger is an iOS-only sculpting alternative; its free plan saves up to three scenes, while scene export requires a subscription.

Creo targets paid professional CAD deployments across desktop, web, and mobile platforms.

Blockbench is the straightforward choice when you need software that is free for any type of project.

Verdict

Choose Spline if you need one tool for 3D creation, animation, real-time rendering, and delivery into web or mobile products. Its integrations and enterprise controls are the main reasons to move beyond a basic modeling app. Look elsewhere if you need unrestricted free exports, month-to-month paid flexibility, or a conventional engineering-CAD focus rather than an interactive design-to-deployment workflow.
