MosaicSlicer is a browser-based 3D printing slicer. Everything runs completely within your web browser, and nothing is sent to any servers or cloud services. It uses CuraEngine for the slicer backend and is mostly compatible with existing Cura printer profiles.
Note: MosaicSlicer is alpha quality software and probably has behavior that is slightly different from Cura. Please double check the generated G-code files in another G-code viewer before printing anything.
