octoview

octoview turns a GitHub file page into a live preview of the file itself. It adds a Preview button on any blob page and renders the file in place, without leaving GitHub or uploading anything. It previews formats GitHub serves as raw bytes or not at all: • 3D Gaussian splats: .splat, .spz (v1-v4), .ksplat, .sog, .ply (3DGS and compressed), .lcc — rendered as true anisotropic gaussians in WebGL2, with size, opacity, falloff and a variance control. • Meshes and point clouds: .glb, .gltf, .obj, .ply, .pcd • HTML reports: Plotly, ydata-profiling, and W&B exports, with the report's own charts running live in a sandbox • Jupyter notebooks: .ipynb, keeping the interactive Plotly outputs GitHub strips • Model files: .safetensors and .gguf tensor tables, plus a Netron-style graph for .onnx • Tables: .parquet, .arrow, .feather • Arrays: .npy, .npz, as heatmaps or images • Scientific images: .exr, .hdr, .tiff, tone-mapped with an exposure slider It works on private repositories because it rides your existing GitHub session. There is no service, no upload, and no personal access token. octoview collects no data and never contacts any server other than GitHub. Open source (MIT). Built with a strict content-security policy: untrusted file content only ever runs sandboxed, with no network access.
