German studio design4real has released Splatmania, a free browser editor for gaussian splats built on PlayCanvas's SuperSplat Editor.
The source is on GitHub under the MIT license, taken from SuperSplat 3.5.2, which is the version number shown in the app's header. GigaSplat took the same route a year ago with depth filtered selection and an alignment tool. Splatmania does not carry the WebMCP tools for AI agents that arrived in SuperSplat Editor 3.7.
Splatmania's depth filter limits rectangle, lasso, brush and click selections to splats whose centers fall between a near and far distance along the view axis, so a wall can be selected straight through the floaters in front of it. Splats outside the range are dimmed or hidden. A large splat whose center sits just outside the range is not caught.
Any number of cameras can be keyframed, each on its own timeline track, and a cut track switches the viewport and the exported MP4 between them, with an optional cross-fade, measured in frames, in the exported video. Key markers can be dragged in the viewport to reshape a camera path. Depth of field is a thin lens blur applied per splat, with a focus picker and keyframeable focus and aperture.
Per layer transitions bring splats in or out with sweep, radial, dissolve, grow, fly-in and wave effects, computed on the GPU so the viewport matches the export. An animatable section plane cuts a building down to its floor plan.
Each camera renders a normal lens view, a mono 360° panorama, or over-under stereo 360° for headsets such as Quest and Pico, with adjustable eye separation. An anchor point tool aligns overlapping scans and can refine the fit with ICP, a quality heatmap shows each scan's weakest areas and a scan comparison shows which scan holds more detail where, and an XGRIDS preset applies the Z-up transform those scans need.
A studio that renders several angles in SuperSplat and assembles them in a video editor can now cut, cross-fade and export the sequence from one browser tab. Splatmania is available now as a free web app.
