Cold CrabbySlice your 3D models anywhere.

Drop in an STL, get print-ready G-code. In your browser, on your desktop, on an iPad, or on your own server — same engine, same output.

Getting started

For teams

Nothing to install

The browser version runs the entire slicer inside the page — walls, infill, G-code, all of it. Your model never leaves your machine. Works on an iPad, or any device that can't run a desktop slicer.

Start slicing

The same result everywhere

Browser, desktop app, iPad and self-hosted server all run the same engine. A model sliced in one gives you the same G-code as the next — no drift between what you preview and what you print.

Made for the device you're on

Touch and pen gestures with palm rejection on a tablet. A native window with OS menus, file dialogs and your system accent colour on the desktop. It fits the device instead of fighting it.

Tour the interface

Calm by default, deep on demand

Sensible defaults and big obvious actions for a first print. Keyboard shortcuts, per-role speeds, variable-width walls and sequential printing when you want them.

Print settings

Talks to your printer

Detect a Klipper machine from its address and its bed size, nozzle and firmware fill themselves in. Slice, then upload and start the print without leaving the app.

Connecting a printer

Yours to host

Run it on your own server and keep every model inside your network, with a shared profile library, shared plate history, and printers that connect properly.
