STL Viewer, Kept on Your Device

Editorial interest 77/100 Selection signal · not a rating of the site

A browser-based viewer for opening, rotating, measuring, and inspecting ASCII or binary STL 3D-model files.

Landing page captured for the 2026-09-02 issue.

Field notes

The viewer accepts both ASCII and binary STL files through drag-and-drop or a file picker, then exposes camera, navigation, display, and measurement controls in the browser. Its details panel reports file size, triangle count, and X, Y, and Z dimensions, while the page cautions that STL geometry carries no declared unit. A separate temporary rendering API is offered for developers who need automated PNG output, but the extract does not describe its access terms.
