A Meshmixer alternative that runs in the browser

Meshmixer is no longer developed and never ran on Linux or a Chromebook. The things most people opened it for before printing work here, in a browser tab: Inspector-style repair, Plane Cut, Reduce, combining and subtracting models, measuring and scaling.

No server processing No account No daily limits

Saves model files for your slicer, never printer code. Opened and sliced in PrusaSlicer, OrcaSlicer, Bambu Studio and Cura.

Edit › Separate Shells → Split into separate parts.

What is not here yet

Sculpting, hollowing, supports, text and freehand selection. This is a first version made for getting a model ready to print; tell us what you miss and it goes on the list.

Questions

Is my model uploaded?
No. The whole thing runs in the page: the model is read and changed by your own browser and never leaves the computer.
Does it work on a Mac?
Yes. It runs in the browser, so it works the same on a Mac, on Linux and on a Chromebook — there is nothing to install.
