Spline alternatives

12 tools that do a similar job, and what makes each one different.

What Spline is

Spline is a design tool for building 3D scenes in a browser and publishing them to the web. It ships two editors, a 3D editor and a 2D editor called Hana. The two share the same interactivity model and the same publishing pipeline, so they are two halves of one tool rather than separate products. Scenes render using WebGPU and fall back to WebGL. There is also a desktop app for macOS and Windows that supports tabs, offline-friendly editing, MCP and system fonts. The 3D editor goes past modelling into behaviour. It includes physics simulation, a particle system and first-person and third-person game controls, which makes it possible to build a scene a visitor can move around in. Imports cover OBJ, FBX with animation and rigs, STL, GLTF, GLB and 3D Gaussian Splats. Exports cover GLTF, GLB, STL, USDZ, OBJ and Spline's own file format, with stills as PNG or JPG and motion as WebM, MP4 or an image sequence. Hana is the 2D editor, with vector networks, booleans, gradients, glass and 3D projection effects, and it publishes to Webflow, Framer, Wix Studio, HTML and JS, Notion and Shopify. On the 3D side, Spline exports code for React projects and offers integrations for Webflow, Framer, Wix Studio, Next.js, Swift and Kotlin. Which of those outputs are actually available depends on the plan. The Free plan costs nothing and includes 2,000 AI credits a month, but web exports carry a Spline watermark. Hobby, at 12 USD per seat per month billed yearly or 15 USD billed monthly, removes the watermark and raises the allowance to 3,000 credits. Pro costs 25 USD per seat per month billed yearly or 30 USD monthly, and is the first plan that can export to Apple and Android apps and to USDZ and STL files. Max costs 60 USD per seat per month billed yearly or 70 USD monthly, includes 10,000 credits, caps video assets at 100 MB, and is where self-hosted export, code export and file version history become available. SAML single sign-on and centralised billing are reserved for the Enterprise plan, which is priced individually and billed annually.

Design for people who do not design for a living. Templates cover presentations, social posts, documents, video and print, and Brand Kits keep colours, fonts and logos consistent across a team. The generative tools handle background removal and image editing. Designers tend to be sceptical of it, and it is nonetheless how most non-designers ship something acceptable.

Design a site and publish it, with no handoff step in between. The canvas works like a design tool and the output is a real responsive site with a CMS, forms, SEO controls and hosting. It suits marketing sites and landing pages where the design is the product; it is a poor fit for anything that needs custom backend logic.

Freemium

The ecosystem around Lottie, the format that ships vector animation as JSON. Animations stay sharp at any size, weigh a fraction of a GIF or video, and can be recoloured or controlled at runtime. The platform hosts a large library, converts from After Effects, and provides players for web and mobile.

Freemium

Interface design in the browser with everyone in the same file, which is what displaced the previous generation of desktop tools. Components and variants keep a design system consistent, auto-layout makes frames respond like real containers, and Dev Mode gives engineers measurements and generated CSS. Prototyping, commenting and version history are built in, so review happens where the work is.

Freemium

Interactive animations built around a state machine rather than a timeline, so a graphic responds to input and events instead of just playing. Runtimes for web, iOS, Android, Flutter, React Native and game engines render the same file everywhere at a fraction of the size of exported video. Used for animated buttons, characters and loaders that react.

Freemium

Open source, unlike Spline

Open source

Visual automation on a canvas, with branching, iteration, aggregation and error handling that hold up under real complexity, the things simpler tools force you to work around. The learning curve is steeper than a linear builder, and the ceiling is much higher. Operations pricing is generally kinder than per-task at volume.

Freemium

Connects applications that were never going to integrate on their own, with the largest catalogue of connectors of anything in this category. A trigger in one app runs steps in others, with filters, paths and formatting in between. The breadth is unmatched; per-task pricing is what pushes high-volume workflows toward self-hosted alternatives.

Freemium

A terminal that treats each command and its output as a block you can navigate, copy and share, rather than an endless scroll. Input behaves like a text editor, history is searchable, and an assistant can read a failing command and suggest the fix. Workflows save parameterised commands for a team. Some of it requires an account, which is the objection people raise most.

Freemium

Generates mobile and web apps from a table your team already maintains. Rows become screens, columns become fields, and the result is installable and works offline. Best for internal tools (inventory, inspections, field data, directories), where the alternative is a spreadsheet somebody edits on a phone.

Freemium

Daily product launches with a badge and a backlink, run transparently, the ranking rules and the code are public, which is unusual in this category. Free and premium submission paths, with the paid one skipping the queue. Positioned as an open alternative to the closed boards, and worth watching for that reason as much as the traffic.

Freemium

Full web applications without writing code: a database, workflow logic, an editor for the interface, and a plugin ecosystem for the rest. Genuinely capable (real businesses run on it), and it is a platform commitment rather than a prototype tool. Performance and cost at scale are the recurring criticisms.
