Spline and Rive are both browser-based tools that bring motion and depth to the web, but they target different outcomes. Spline is a 3D scene editor — you build hero section graphics, product visualizations, and interactive 3D environments and export them to React or embed them on the web. Rive is an animation and state machine tool — you create responsive, interactive animations for app UI elements and export tiny runtime files that play natively in iOS, Android, Flutter, React Native, and the web. If you are building a 3D hero section or a WebGL product visualization, choose Spline. If you are building micro-interactions, loading animations, or stateful character animations for a production app, choose Rive.

3D design and scene building
Spline is the clear winner for 3D. It provides a full 3D modeling environment in the browser — primitives, boolean operations, materials, lighting, physics, and camera controls — that lets designers build rich 3D scenes without installing Blender or Cinema 4D. The learning curve is gentle enough that UI designers without 3D backgrounds can create professional-looking scenes in a few hours. Rive has no 3D capability at all — it is a 2D vector animation tool. If your project involves 3D objects, depth, or spatial composition, Rive is not an option and Spline is the right tool. The distinction matters because Spline's 3D scenes produce WebGL output that looks dramatically different from anything Rive can generate — they are not competing for the same design outcomes, they are solving different visual problems.
Interactive animations and state machines
Rive wins decisively for interactive animation with stateful behavior. Rive's state machine editor is the most capable in this category — you can define inputs (boolean, number, trigger), build transition conditions, create nested state machines, and connect animations to application logic through a clean runtime API. An animation can respond to user interaction, application state, or data-driven inputs from your code. The practical result is animations that behave like code — a loading spinner that transitions to a checkmark on success, a character that reacts to a user's score, a button that morphs between states. Spline supports basic mouse-follow interactivity and scroll-based triggers, but it does not offer Rive's depth of stateful control. For any animation that needs to respond to application logic rather than just user mouse position, Rive's state machine is the right tool.
Production performance and file size
Rive has a significant performance advantage for production app deployment. Rive animations are vector-based .riv files typically ranging from 10KB to 200KB — small enough to include in a mobile app bundle without impacting load times. The Rive runtime renders animations natively on each platform at 60fps, using the device's GPU efficiently because the format is designed specifically for real-time playback. Spline's WebGL output is fundamentally heavier — a moderately complex 3D scene can generate 5–20MB of JavaScript, shaders, and textures before any optimization. That is acceptable for a marketing landing page where a hero section is the main attraction, but it is not practical for a mobile app where every kilobyte of bundle size matters. If you are building for iOS or Android and performance is a constraint, Rive is the practical choice; Spline's output format is primarily suited for web contexts where the tradeoff is accepted.
Cross-platform support
Rive's runtime ecosystem is a major differentiator. Official runtimes exist for web (JS/WASM), iOS (Swift), Android (Kotlin/Java), Flutter, React Native, Unity, and Unreal Engine — all maintained as open-source MIT-licensed libraries. You create the animation once in the Rive editor and it plays identically across every platform using the native runtime. This write-once, play-anywhere model is genuinely powerful for product teams building across web and mobile simultaneously. Spline's exports are primarily web-focused — React component, iframe, and video. A Spline scene can be embedded on any website but does not have native iOS or Android playback. Teams building cross-platform products where the same animation needs to work in a Flutter app and a React web app will find Rive's runtime coverage removes a significant engineering problem.
Developer integration and handoff
Both tools have reasonable developer handoff stories, but Rive's is more production-ready. Rive generates a .riv file that is loaded by a one-line import in whatever runtime your engineer is using. The API for controlling state machine inputs from application code is clean, typed, and well-documented — developers can trigger animation states, read back values, and listen to animation events with minimal setup. Spline's React export generates a usable component, and the iframe embed is the simplest possible integration, but the WebGL rendering context adds complexity for performance-sensitive applications and the interactivity API is more limited. Spline also provides a JavaScript library for more advanced integration, but it requires more custom code for complex interactions. For teams where the designer and developer are iterating together on animation behavior tied to application state, Rive's handoff model is more precise.
Pricing and free tier generosity
Both tools offer genuinely useful free tiers, but Rive's is slightly more generous for individual creators. Rive's free tier includes unlimited personal projects with no cap on file count or exports — the limit is on team features and private sharing. Spline's free tier allows unlimited public projects and one private project. For solo designers building a portfolio or experimenting with animations, both are effectively unlimited. At the team level, Spline's Team plan is $16/editor/month while Rive's Starter team plan is $45/month for up to 3 editors — Spline is cheaper per seat for small teams. For larger teams or organizations with multiple editors, compare the full pricing pages carefully as the tiers diverge. Neither tool is expensive relative to the design tool category; the pricing difference is unlikely to be a deciding factor unless budget is extremely tight.
Pricing deep-dive
Spline
- Free: unlimited public projects, 1 private project, basic export.
- Indie: $12/month — unlimited private projects, priority rendering.
- Team: $16/editor/month — collaboration features, team libraries, advanced export.
Rive
- Free: unlimited personal projects, community access, all runtimes.
- Starter: $45/month for up to 3 editors — private files, team sharing.
- Pro: custom pricing — dedicated support, advanced collaboration, SLA.
Pricing verdict: Spline is cheaper per editor for small teams at $16/editor/month vs Rive's $45/month Starter. For solo designers, both free tiers are functional and neither imposes meaningful export limits. The pricing difference is not significant enough to drive the decision — choose based on whether you are building 3D scenes for web (Spline) or interactive animations for apps (Rive), not on price.
How to migrate from Spline to Rive
What real users say
Spline: Spline has strong enthusiasm in the web design and no-code community — the ability to create 3D scenes in a browser without Blender is frequently praised as democratizing 3D for web designers. Developers appreciate the React component export. Common criticisms include WebGL performance on lower-end devices, the learning curve for physics and constraints, and occasional rendering inconsistencies between the editor preview and the exported output.
Rive: Rive has a devoted following among product designers and mobile developers, particularly in the Flutter and React Native communities where Rive animations are considered the production standard for complex UI motion. Users consistently praise the state machine model, the lightweight runtime files, and the cross-platform consistency. The most common complaint is that the free tier's team collaboration limits feel restrictive for small studios, and the editor's learning curve for state machines takes time to master.

Final verdict
Choose Spline if...
- Choose Spline if you are building 3D hero sections, product visualizations, or interactive 3D marketing experiences for a web audience — this is exactly what Spline is designed for.
- Choose Spline if your team is a web-focused design team that wants to add 3D depth to landing pages without learning Blender or Three.js directly.
- Choose Spline if your output is browser-only and the richer visual language of 3D scenes is central to the design intent, and performance tradeoffs of WebGL are acceptable.
Choose Rive if...
- Choose Rive if you are building interactive animations for a product app that runs on iOS, Android, Flutter, or web — Rive's cross-platform runtimes make it the standard choice for production app animation.
- Choose Rive if performance and file size matter — Rive's .riv files at 10–200KB are orders of magnitude smaller than equivalent Spline WebGL scenes, which matters for mobile app bundles.
- Choose Rive if your animations need to respond to application state through a state machine — Rive's input/transition model is purpose-built for animations that behave differently based on user or data-driven conditions.
Consider neither if: Consider neither if your animation needs are simple enough to be handled with CSS animations or Lottie files. For straightforward loading spinners, hover effects, and transition animations, CSS keyframes or Framer Motion in React are lower-overhead solutions that avoid introducing a dedicated animation tool into your workflow.
