Kiri:Moto review
A free, open-source browser tool for hobby-scale slicing and fabrication workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
Kiri:Moto is a free, open-source browser application for preparing fabrication jobs, particularly suited to users who want 3D-printing slicing alongside CNC and laser workflows. It supports FDM and SLA modes and a sequence of arranging, slicing, previewing, and exporting jobs. The application runs processing locally in the browser, rather than through a cloud slicing service, and is available for web, Windows, macOS, and Linux, with APIs for embedding and JavaScript slicing.
Its breadth is useful for hobby-oriented workflows: Kiri:Moto imports OBJ, STL, and 3MF models, as well as SVG, JPG, and PNG files that can be auto-extruded into 3D parts. It generates G-code and other machine-ready output for printing, CNC milling, and laser cutting. Device configuration and predefined profiles support setup across fabrication devices. Connections include Onshape, Lychee Slicer, SimplyPrint.io, Sienci CAMLab, and Thingiverse, while the GridSpace OctoPrint plugin can send jobs directly to local printers. That mix makes it more than a slicer, though its emphasis is still fabrication preparation rather than a comprehensive production CAM environment.
Kiri:Moto is a strong fit for users seeking a no-cost, browser-based tool with several hobby fabrication paths and local processing. The open-source model means the product is free; it is not presented as a tiered subscription offering. Users who need cloud slicing should look elsewhere, as should those who require an integrated workflow for production CAM or depend on automatic supports, print monitoring, multi-material preparation, or model repair. The documented feature set supports slicing and job preparation, but those additional capabilities should not be assumed to be built into Kiri:Moto.
Kiri:Moto pros and cons
- Where it wins
- Slices FDM and SLA jobs in a browser, with G-code generation
- Supports 3D printing, CNC milling, and laser toolpaths
- Imports mesh and image formats, including OBJ, STL, and 3MF
- Where it doesn't
- Its workflow centers on 3D printing and hobby-oriented fabrication
- Local browser processing is not cloud slicing
- Does not verify automatic supports, monitoring, or model repair
