SuperSplat is a free and open source browser-based editor for working with 3D Gaussian Splats, built entirely on web technologies with no installation required. The tool runs at https://superspl.at/editor and enables users to inspect, edit, optimize, and publish 3D Gaussian Splat data directly in their web browser. Written primarily in TypeScript, the project leverages WebGL and WebGPU for real-time GPU-accelerated rendering of point cloud data, integrating with the PlayCanvas ecosystem and utilizing the PCUI framework for its user interface.
The repository serves as a practical implementation of 3D Gaussian Splatting technology, a technique for representing and rendering 3D scenes. The editor provides interactive tools for manipulating splat data, making it accessible to users who need to work with this emerging 3D representation format without requiring specialized desktop software. The project includes comprehensive localization support with JSON-based locale files for multiple languages, and developers can add new language translations by creating locale files and registering them in the localization system.
Development setup requires Node.js 18 or later, with a straightforward workflow involving cloning the repository, installing dependencies, and running a local development server on port 3000. The build system automatically rebuilds SuperSplat when source files change, allowing developers to see modifications by refreshing their browser. The documentation emphasizes clearing browser caches during development to ensure changes are properly reflected.
According to GitGenius activity tracking, the repository has demonstrated steady engagement with 9,441 stargazers as of the most recent check. The project maintains active issue and pull request management with a median response latency of 2.2 hours across 345 tracked items, indicating responsive maintainership. Feature requests represent the most common issue type with 62 tracked instances, followed by bug reports with 31 instances and enhancement requests with 18 instances. The core development team includes slimbuck as the most active contributor with 727 tracked events, followed by willeastcott with 279 events and simonbethke with 54 events.
The project connects to related repositories through overlapping contributors, including the main PlayCanvas engine repository, COLMAP for 3D reconstruction, and the original Gaussian Splatting research implementation from GraphDeco-INRIA. This network reflects SuperSplat's position within the broader ecosystem of 3D Gaussian Splatting tools and the PlayCanvas platform. The editor is documented through a user guide available on the PlayCanvas developer portal, with additional resources available through the PlayCanvas blog and community forum, providing users with comprehensive support for learning and utilizing the tool's capabilities.
