Kiri:Moto
Kiri:Moto is a free, browser-based slicer for 3D printers, CNC mills, and laser cutters.
What Kiri:Moto is
Kiri:Moto is a free, browser-based slicer for 3D printers, CNC mills, and laser cutters. Its main modes cover CAM, FDM, SLA, and LASER workflows. It imports OBJ, STL, and 3MF files, and can turn SVG, JPG, and PNG images into 3D parts through auto-extrusion. The maker says processing stays in the browser: it does not collect personal data or send or store user data in the cloud. The browser sandbox also prevents access to hard-drive data without user action. Kiri:Moto is available as a web app, desktop Electron binaries, a Docker setup, and a command-line utility; it can also be embedded in an iframe with a messaging API. An OctoPrint plugin can spool jobs to printers on a local network, and an Onshape extension can load parts from an Onshape document. For unsupported printers, users can customize a similar device or import a PrusaSlicer INI file, but macro logic is not converted automatically. The source is available under the MIT license.
Good
- Free plan provides web app access without ads.
- Imports OBJ, STL, and 3MF files.
- Auto-extrudes SVG, JPG, and PNG into 3D parts.
- Can spool jobs through its OctoPrint plugin.
- Offers desktop, Docker, and command-line options.
Watch out
- Macro logic is not automatically converted for unsupported printers.
- Additional modes extend LASER but are not first-class modes.
Who it suits
Kiri:Moto suits makers, hobbyists, professionals, students, and educators who need slicing or fabrication workflows across supported printer and cutter modes. It may also fit users who want browser-based processing or command-line and self-hosted deployment options.
Verdict
Kiri:Moto combines several fabrication modes with multiple deployment choices and file-import options. Check printer compatibility and the macro-conversion limitation before relying on a profile.
