Spline and Rive both get lumped together as "interactive design tools for the web," and that grouping hides how different they are. Spline is a 3D scene editor. Rive is a 2D animation tool built around a state machine. Picking between them is less about price and more about what you are actually trying to put on screen.
What Spline actually does
Spline is a browser-based 3D design tool for web and product designers who want 3D on a page without learning Blender or Three.js. You build a scene in the browser, then export it as an embeddable snippet, a React component, an iframe, or a static image. The 3D content renders in real time through WebGL. Boolean operations, physics simulation, and animation timelines are all in the editor, and interactive events work without writing code.
The learning curve is gentle for anyone who has used Figma. A designer can produce a usable scene, with basic shapes, materials, and animation, in a few hours. Typical uses are 3D hero sections, interactive product showcases, and animated 3D icons.
The honest limits: Spline trades depth for accessibility, so it is not a substitute for Blender or Cinema 4D. Material and lighting options are limited. And the most common complaint is performance. A scene that looks great in the editor can hammer a low-end phone once it is on a real page, so budget time for optimization before you ship.
What Rive actually does
Rive is an animation tool for lightweight animations that stay interactive at runtime. The key difference from After Effects or Lottie is that a Rive animation is not a fixed video. It responds to user input, app state, or API data through a state machine. You design in the Rive editor, export a small binary file, and play it with official runtimes for Flutter, React, iOS, Android, WebGL, and Unity. The runtime is open source and free for commercial use.
File sizes are the big practical win. A complex animated character can come in under 100KB, far below video or GIF. Rive is used for character animation, loading states, interactive onboarding, and UI micro-animations.
The honest limits: the state machine has a real learning curve, roughly one to two weeks before it feels natural. Runtime integration needs developer work, so a designer cannot ship a Rive animation alone. And Rive is animation, not full design or 3D, so it is the wrong tool for linear marketing video.
Current pricing, checked against both live pricing pages
Both entries in our database were out of date, so we verified against each vendor's own pricing page. Both pages have a yearly and monthly toggle, so treat the lower figures as the annual-billing rates.
Spline's free plan is limited, with capped files and a watermark on web exports. Hobby is $12 per seat per month billed annually, or $15 billed monthly, and adds unlimited 3D and 2D files, no watermark on web exports, and higher-resolution exports. Pro is $25 per seat per month annually, or $30 monthly, and adds unlimited folders and projects, unlimited scenes per file, and Apple and Android exports. Max is $60 per seat per month annually, or $70 monthly, and includes 10,000 AI credits per month.
Rive's free plan covers 3 collaborative files. Cadet is $9 per seat per month, limited to 3 seats, with unlimited files and .riv export. Voyager is $32 per seat per month, up to 25 seats, and adds libraries and embed URL hosting. Enterprise is $120 per seat per month for organizations above $10M in annual revenue, with SSO and SOC 2 Type II.
The practical comparison: at the entry paid tier Rive is cheaper ($9 versus Spline's $12), but a team of more than three people has to move to Voyager at $32 a seat.
Where the two genuinely diverge
Spline produces scenes. Rive produces behavior. If you want a rotating product model, a 3D hero, or a floating icon, that is Spline. If you want a button that reacts, a character that changes state when a user taps, or an onboarding flow driven by app data, that is Rive.
The output differs as well. Spline exports embeds and React components that a frontend developer can drop in with little code. Rive exports a tiny binary that a developer wires up through a runtime, which gives more control and a much smaller payload, at the cost of more engineering.
Real cost for different teams
A web designer adding a 3D hero to a marketing site: Spline's free plan is enough to learn on, and Hobby at $12 to $15 per seat removes the watermark for a real launch.
A mobile team building interactive onboarding or character animation in Flutter or React Native: Rive at $9 per seat on Cadet fits a small team, and the open-source runtime costs nothing extra.
A team of five or more animators sharing libraries: Rive's Voyager at $32 per seat is the tier that supports that, so budget for it rather than for Cadet.
A team that wants both 3D and interactive motion: they solve different problems and are not substitutes, so plan for two tools rather than forcing one.
A solo designer with no developer support: Spline is the more self-sufficient choice. Rive's payoff depends on a developer wiring up the runtime.
What actually breaks in practice
Spline's failure mode is performance. Complex scenes with many objects slow down on mobile and older machines, and fixing that is manual optimization work that the editor does not do for you.
Rive's failure mode is the handoff. The state machine takes time to learn, and an animation is not done until a developer has integrated the runtime, so projects stall when design and engineering are not in step.
Data handling and where your files live
Spline is hosted in the US. Public projects are visible to everyone, and private work needs a paid plan. Its privacy documentation is thin for a growing startup, and its data-for-AI stance is listed as unclear, so check the current terms if that matters to you. Projects can be exported and deleted.
Rive is also US hosted, with files stored in the cloud on paid plans and a desktop runtime that processes locally. Our listing records no data selling and no AI training on customer files, though Rive's editor now includes an AI agent on its plans, so review its terms if you handle sensitive assets. Files are exportable.
Switching between them
There is no real migration path, because the two tools do different jobs. If you are moving from Lottie to Rive, expect to rebuild your animations to take advantage of state machines. If you are moving a 3D element out of Spline, you will be rebuilding it in another 3D tool, since Spline's export formats are limited.
Onboarding and day-to-day usability
Spline needs an email or Google signup with a free tier and no credit card. The editor loads in the browser with nothing to install, a first scene with shapes, materials, and animation takes about 30 minutes for a designer used to 2D tools, and export as an iframe or React component takes a few clicks.
Rive uses the same kind of signup, and its editor also runs in the browser. The state machine needs some reading of the documentation, and a first interactive animation driven by input takes about one to two hours to build.
Who does the work: designers versus developers
The people involved matter as much as the features. Spline is built so that one designer can go from an idea to a live embed with little help, and the friction shows up later, in performance tuning that often needs a developer's eye. Rive front-loads the collaboration instead. A designer builds the motion and the state machine, then a developer connects it to real app events, so the two roles have to agree on what each state and input is called before anything works. Teams that already ship together, such as a small mobile team, usually find that handoff natural. A designer working alone often finds it a wall.
There is also a difference in how each fails quietly. A slow Spline scene is easy to notice, because the page stutters. A Rive animation wired to the wrong state simply looks dead, and it can take a while to work out whether the fault is in the file or in the integration. Neither is a dealbreaker, but both are worth knowing before you promise a delivery date.
Which one to actually pick
Pick Spline if you want 3D on a website and you are a designer or frontend developer who needs results quickly, and you are willing to spend time on performance tuning.
Pick Rive if you are building an app or game with animations that respond to input, and you have a developer to integrate the runtime.
For teams still deciding, ask what the thing on screen has to do. If it only needs to look three-dimensional, Spline. If it has to react, Rive.
