G-code viewer
Open a .gcode or .gcode.3mf file and see every move that lays down plastic, layer by layer. It opens on your device: the file is never uploaded.

What it shows
Every move that lays down plastic, layer by layer, in the colors your slicer gives each line type, or in a real filament you pick from our library. Hide a line type, show the travel moves, play the print or step through it move by move, and turn it to any side. It also shows what the slicer wrote into the file: the print time, the filament and how much of it, the printer and the layer height.
Files it opens
- .gcode.3mf from Bambu Studio and OrcaSlicer, one plate at a time.
- .gcode from Bambu Studio, OrcaSlicer and PrusaSlicer.
- Not yet: PrusaSlicer’s binary .bgcode, or a 3MF that hasn’t been sliced.
- On a phone, files up to a million moves. Larger ones open on a computer.
Your file stays on your device
The viewer reads your file in your browser. It isn’t uploaded, and we keep nothing from it: close the page and it’s gone.
Questions
Is it free?
Yes, with no account. The viewer runs in your browser, and your file never leaves your device.
Does it open a .gcode.3mf from Bambu Studio?
Yes, one plate at a time, with the plate’s picture when the file has one. A .gcode.3mf from OrcaSlicer opens the same way.
Why won’t my PrusaSlicer file open?
If it ends in .bgcode, it’s binary G-code, which the viewer doesn’t read yet. Untick Supports binary G-code and export again: the guide shows where.
How is it different from my slicer’s preview?
It’s the same kind of view, in a browser tab, with nothing to install. And it can show your print in a real filament’s color, from a library of 2,251.
