G-Code Viewer — GCodeView

Open the G-code file you actually have — and see it.

OPENS MODERN SLICER OUTPUT

PrusaSlicer, OrcaSlicer, Bambu Studio, Cura, SuperSlicer, Klipper, Marlin. If your slicer wrote it, GCodeView opens it — no "file could not be read", no blank screen. The parser is built to tolerate every flavor, so your file just works.

HANDLES LARGE FILES

A 200 MB G-code file opens in seconds. The parser streams from disk and renders compact toolpath buffers, so big prints don't choke the phone.

SEE THE PRINT, LAYER BY LAYER

The toolpath renders in 3D with rotate and zoom. Scrub the layer slider to watch the print grow, inspect a single layer, or show travel moves in dim. Read what the file says: estimated time, filament used, layer height, temperatures, dimensions.

FREE, NO ADS, FULLY OFFLINE

No account, no subscription, no ads. Your files never leave your device.

FEATURE COLORS

Color the toolpath by slicer feature type — perimeter, infill, support, bridge — with a legend.
