How to use SuperSplat: edit and publish Gaussian Splats in your browser

Updated · written with AI from the project's own documentation and checked against our catalogue data

SuperSplat is a free, open source editor for 3D Gaussian Splats, a way of capturing real-world scenes as point-like clouds. This guide shows you how to open the hosted editor, what it is meant for, and how to run it locally if you want to work on the code. After reading, you will know where to start, what the README says the tool can do, and where to find the full user guide.

Quick start

  1. 1Open the editor. Go to https://superspl.at/editor in a web browser. Nothing needs to be downloaded or installed for the hosted version.
  2. 2Load your scene. Bring your 3D Gaussian Splat scene into the editor so you can inspect it.
  3. 3Edit and optimize. Use the editing tools to clean up or trim the scene, then optimize it as needed.
  4. 4Publish. Export or publish the finished splat scene for web use.
  5. 5Read the User Guide. Follow the linked PlayCanvas User Guide for detailed instructions on each feature.

What is SuperSplat and what can you do with it?

SuperSplat is a tool for inspecting, editing, optimizing and publishing 3D Gaussian Splats. The README describes it as built on web technologies and running in the browser, so there is nothing to download or install to use the hosted version.

It is focused on Gaussian Splats rather than general 3D modeling. The README points to the User Guide for detailed instructions on using the editor.

  • Inspect a splat scene
  • Edit a splat scene
  • Optimize a splat scene
  • Publish a splat scene

Open the SuperSplat editor in your browser

The quickest way to try SuperSplat is the hosted live version at superspl.at/editor. You do not need to install anything. Open the link in a web browser and start working with your scene.

The README does not list specific browser requirements for the hosted editor, so check the User Guide if you run into compatibility questions.

  • Go to https://superspl.at/editor in your browser
  • Load your Gaussian Splat scene into the editor

Run SuperSplat locally for development

If you want to run the editor on your own machine, for example to change the code, the README says you need Node.js 20.19 or later. Clone the repository, install dependencies, then build and start a local web server.

When changes to the source are detected, SuperSplat is rebuilt automatically. Refresh your browser to see the changes. The README also suggests disabling network caching and clearing application caches so you see the latest build.

  • Make sure Node.js 20.19 or later is installed
  • Clone the repository and move into its folder
  • Install dependencies
  • Start the development server
  • Open http://localhost:3000 in your browser
git clone https://github.com/playcanvas/supersplat.git cd supersplat npm install npm run develop

Use WebMCP tools with SuperSplat

The README says SuperSplat exposes native browser WebMCP tools for scene inspection, selection, editing, camera control and import/export. The tool contract, browser requirements and verification commands are described in the docs/webmcp.md file in the repository.

Check that file for the exact details before relying on these tools in a workflow.

Change the interface language

SuperSplat supports several languages, and the README links to the list of supported locales in the static/locales folder. To test a translation, run the development server and open the editor with a language code in the URL.

To add a new language, add a locale JSON file to static/locales and register the locale in src/ui/localization.ts, as the README describes.

  • Test a locale by opening http://localhost:3000/?lng=<locale>, replacing <locale> with a code such as fr, de or es
  • Add a new file named <locale>.json in static/locales
  • Add the locale to src/ui/localization.ts
http://localhost:3000/?lng=<locale>

What people use it for

  • Clean up or trim a Gaussian Splat scene without installing software
  • Edit splats while developing with PlayCanvas
  • Prepare splat scenes for web publishing
  • Try the editor quickly from a browser
  • Change the code or translations by running SuperSplat locally

Frequently asked questions

Is SuperSplat free?

The README describes SuperSplat as a free and open source tool. The repository is licensed under MIT, as shown on the project page.

Do I need to install SuperSplat?

No, the README says the editor runs in the browser, so there is nothing to download or install to use the hosted version at superspl.at/editor.

What do I need to run SuperSplat locally?

The README says to have Node.js 20.19 or later installed, then clone the repository, run npm install and npm run develop, and open http://localhost:3000.

Can I use SuperSplat offline?

The README does not describe an offline mode. It highlights the browser version, so do not assume offline use is supported.

Is SuperSplat a general 3D modeling tool?

No. It is focused on 3D Gaussian Splats, so it is not a substitute for general 3D modeling software.

Where can I find detailed instructions?

The README links to the PlayCanvas User Guide for SuperSplat, and to the WebMCP docs in docs/webmcp.md for the tool contract and browser requirements.

Our verdict

SuperSplat suits people who want to clean up, trim or prepare a Gaussian Splat scene quickly in a browser, and developers working with PlayCanvas. If you need an offline tool, a general 3D modeler, or a simple viewer only, the README suggests you should look elsewhere.
