Web based Gaussian Splatting just got a major upgrade. Forge, a new renderer developed by World Labs, brings powerful 3DGS rendering to the browser via Three.js. There are no plugins, no special hardware, just fast, high quality visuals that work on nearly every device. It’s lightweight and open source under the MIT License, meaning you can use it commercially.

Forge integrates directly into the Three.js rendering pipeline, enabling scenes that mix splat-based and mesh-based geometry with correct depth sorting and animation support. Forge supports a wide range of splat file formats including .PLY (with optional compression), .SPZ, .SPLAT, and .KSPLAT. Developers can load and render multiple splat objects at once, even from different camera viewpoints, making it especially powerful for interactive environments, technical demos, or creative projects.

It's built to be fast and should be compatible with over 98% of WebGL2-supported devices, including lower-powered mobile phones and tablets. The renderer also offers full interactivity. Splats can be dynamic and be transformed, animated, and edited in real time. Developers can tweak splat color, displacement, and even use skeletal rigs to animate objects with natural motion. For shader authors and technical artists, Forge includes a GPU-based shader graph system that allows splats to be generated or modified directly on the graphics card, without needing to pre-bake.

Getting started with Forge is as straightforward as dropping in a script tag. Within minutes, you can render your first Gaussian Splat with just a few lines of JavaScript. Forge is available via CDN, NPM, or you can clone the repo and build it yourself. There’s even a Glitch starter template for anyone who wants to experiment without setting up a local environment.

And for developers working offline or running production builds, Forge provides tooling to compress .PLY splats into .SPZ files for faster loading, along with commands to fetch and cache assets locally. The core renderer is powered by Rust and WebAssembly, offering both performance and portability.

This is one of the first public releases that we have seen from the star studded World Labs team. It's been almost exactly six months since they previewed their single image to explorable 3D using gaussian splatting. With Forge now available, we may be witnessing the start of a broader rollout of tools from World Labs.

More importantly, Forge helps push Gaussian Splatting beyond research papers and into real world production, exactly where it belongs.
