## Marble

Marble is a generative 3D platform built by World Labs. Instead of modelling every object by hand, you describe a scene in text, upload a reference photo, or supply video, and Marble produces a coherent, navigable 3D world with consistent geometry, materials, and lighting. Because worlds are generated as spatial scenes rather than flat images, you can move a camera through them and look at the same place from multiple angles.

The workflow is built around iteration. After a world is generated you can refine it, extend it, or combine it with other elements, then explore the result inside the browser editor. Marble supports the kinds of tasks that usually demand a full 3D pipeline: concepting environments for films and games, building sets for virtual production, sketching spatial ideas for architecture and interiors, and producing immersive backdrops for presentations or experiences.

Outputs are designed to travel. Worlds can be exported for use in other 3D tools and engines, and shared with collaborators or an audience through a link. Access to Marble is arranged through World Labs, and because the product is evolving quickly, the available plans, limits, and export options are best confirmed on the official site.

**Pricing & Plans:** Marble is offered directly by World Labs with tiered access; a free entry point has been provided alongside paid tiers that raise generation allowances and unlock higher-resolution or commercial-oriented use. Exact limits and prices change frequently, so check the official site for current figures.

- **Text-to-3D world generation:** Describe a scene in natural language and receive a coherent, explorable 3D environment with consistent geometry and lighting.
- **Image and video-to-3D input:** Use a reference photo or footage to generate a 3D world that matches the look, layout, and atmosphere of your source material.
- **In-browser world editing:** Refine, expand, and rearrange generated worlds inside the web editor instead of rebuilding scenes from scratch in a modelling tool.
- **Export for 3D pipelines:** Move worlds into external 3D tools and engines so they can be used for game development, visual effects, or further design work.
- **Sharing and collaboration:** Publish a world through a shareable link so teammates, clients, or audiences can explore it directly in a browser.

**Strengths:** Produces navigable full 3D worlds, not just single-view images; Accepts text, image, and video as starting points; Worlds can be edited, exported, and shared through links

**Limitations:** Generation is compute-intensive, so allowances are limited on entry tiers; Sustained professional use requires a paid plan and, for some use, direct contact with the vendor

## Spline

Spline brings 3D design into the browser so designers, developers and marketers can build interactive 3D without a heavyweight desktop pipeline. The editor covers primitives, booleans and sculpting, plus 3D generation, layered materials, lighting and post-processing. Animation and interaction are handled through states, keyframes, events and physics, and the whole file runs with real-time performance.

A standout feature is agent collaboration: you can connect assistants such as Claude, ChatGPT, Cursor or Codex through Spline MCP so an agent can read and write to the live scene, then hand it back to your team for refinement in the very same file. Because everything the agent produces is a regular Spline object, teammates can select, restyle, animate or undo it by hand at any point.

Publishing targets the modern web and mobile stacks. You can share a link, embed a viewer or export code for web (WebGPU/WebGL), add a native SwiftUI or Metal view for Apple apps, or build for Android with Vulkan and Jetpack Compose. Spline is used for interactive product design, brand and marketing pages, immersive experiences, gamified sites and education.

**Pricing & Plans:** Spline offers a free tier to start building in 3D, with paid plans for individuals and teams and a dedicated Enterprise offering. Exact seat and feature limits per tier are listed on the Spline pricing page.

- **In-browser 3D editor:** Model with primitives, booleans and sculpting, and use 3D generation to create objects from prompts.
- **Materials, lighting and post-processing:** Apply layered materials, lights and post-processing effects to give scenes a polished, production-ready look.
- **Animation and interaction:** Build interactivity using states, keyframes, events and physics so scenes respond to scroll, hover and other triggers.
- **Agent collaboration over MCP:** Connect AI coding agents to read, write and frame the live scene, then refine the same file by hand with your team.
- **Ship to web, iOS and Android:** Publish a link, embed a viewer, export code for the web, or create native Apple and Android views and builds.

**Strengths:** Runs entirely in the browser, so there is no heavy install or setup barrier; Real-time collaboration and agent workflows keep designers and developers in one shared file; One scene publishes to web, iOS and Android with platform-native renderers; Broad feature set spanning modeling, materials, animation, physics and interaction

**Limitations:** Advanced 3D work may still require a learning curve for newcomers; Performance and export options depend on the device and platform you target; Team and enterprise capabilities sit behind paid tiers
