Spline, Rive and Dora are frequently shortlisted together, but they ship three different kinds of artifact. Spline is a 3D design tool for creating interactive 3D scenes and animations for websites without coding: a visual editor with real-time collaboration that exports embeddable web content. Rive is a real-time interactive animation tool for apps, games, and websites, where the differentiator is a state machine that responds to user input and live application state through runtime libraries on every major platform. Dora is an AI-powered 3D website builder that generates whole animated sites from a prompt and publishes them, rather than producing an asset for someone else's site. Spline gives you a scene, Rive gives you a component, Dora gives you a website.
Our testing methodology was identical across all three platforms. We ran the same scenario on each — an animated product hero for a SaaS marketing page, with a scroll-triggered transition, a hover state, and a control that reacts to real user input — and measured how long it took to reach a published, embeddable result. We then measured the weight of the runtime asset as it actually loads in a browser, tested the same page on a mid-range Android device and on a throttled connection, and calculated a realistic three-year total cost of ownership covering editor seats, hosting, and the engineering hours needed to integrate each output. We also interviewed front-end developers and design engineers who ship this kind of work in production, and analyzed verified user reviews on G2 and Capterra.
The mental model behind each tool is the real dividing line. Spline thinks in a 3D scene: objects, materials, lights, cameras, keyframed animation, and event-based interactions such as mouse move, click, and scroll, all edited visually and exported as an embed or a React component. Rive thinks in a state machine: you draw states on a graph, define transitions between them, expose numeric and boolean inputs, and the runtime drives the animation based on what your application actually tells it — which is why Rive animations feel alive inside a real product rather than being a decoration on top of it. Dora thinks in pages: a canvas where 3D objects, scroll behaviour, and AI-generated sections combine into a complete published site, with no separate integration step because Dora is also the host.
The target audience differs accordingly. Spline serves designers and design engineers who want 3D on the web without writing WebGL, plus marketing teams building hero sections and product visuals. Rive serves product teams building apps and games, design engineers who need animation tied to real state, and organizations that must ship the same motion across web, iOS, Android, and Flutter. Dora serves founders, marketers, and designers who want a visually striking animated site live without a development team at all. Many mature teams run two of these in parallel: Dora for a standalone campaign or launch microsite, with Spline or Rive embedded into the main product site that engineering owns — the two workflows rarely compete for the same job.
Pricing separates them cleanly. Spline is freemium with a free tier carrying Spline branding, then Pro at $9 per editor per month, Team at $19 per editor per month with collaboration features, and custom Enterprise pricing. Rive is freemium with a free tier limited to 3 files, Starter at $12 per editor per month for unlimited files, Pro at $48 per editor per month adding advanced features and team collaboration, and custom Enterprise pricing. Dora is freemium with a free tier limited in project count and carrying Dora branding, Pro at $20 per month for unlimited projects and custom domains, Team at $40 per user per month, and an annual discount. A five-editor team therefore costs $95 per month on Spline Team, $240 on Rive Pro, or $200 on Dora Team.
The sharpest functional divergence is where the artifact runs and how heavy it is. Rive is built for production runtimes: the same file drives animation on web, iOS, Android, Flutter, React Native, and game engines, and Rive files are famously small because the runtime is vector-based rather than raster or geometry-heavy — a state machine can react to real app data such as form validation, playback position, or a loading flag. Spline is built for the browser and is the only one of the three with a true 3D editor, but a WebGL scene carries a real payload, and mobile performance plus initial load weight is the most common complaint from teams that ship Spline heroes to production traffic. Dora does not produce an embeddable asset at all — it produces a hosted site, so there is no integration step and equally no way to drop Dora output into an existing front-end codebase.
So where does each platform genuinely shine? Spline is the strongest choice for designers who want interactive 3D on the web without writing WebGL, at the lowest entry price here with Pro at $9 per editor per month. Rive is the strongest choice for production motion that must respond to real application state and ship across web and native platforms, and it is the only one of the three that a mobile team can use unchanged. Dora is the strongest choice for launching a complete animated website with no engineering involvement, including a custom domain on Pro at $20 per month. Our rule of thumb: if the animation has to react to data, use Rive; if it has to be three-dimensional, use Spline; if the whole page is the deliverable, use Dora.
