LichtFeld Studio

LichtFeld Studio is a free, open source desktop application for 3D Gaussian Splatting. It turns photos or video into photorealistic 3D scenes that render in real time, and it covers the full workflow in one workspace: training, live inspection, scene editing and export, all run locally on the user's GPU. Training runs on a native C++23 and CUDA core with save and resume. Editing tools include brush, lasso, polygon, crop, align and compose operations on the live scene. The application embeds Python plugins and MCP endpoints, so users can build custom panels, operators and batch tools, or drive the app from external agents and workflows. Version 0.5.4 added a native project file format with a project manager, an online gallery in beta, faster training with lower memory use, and normal guided training. The site also points to an optional iPhone capture app for 4K footage and LiDAR depth. It is aimed at researchers, 3D artists and developers working with scanned scenes, and runs on Windows and Linux. The source is released under the GPLv3 license on GitHub, and the application is free to use. Prebuilt Windows binaries are available through the LichtFeld portal for a minimum contribution of $30, which the project states funds ongoing development.
