Umamo is a cross-platform editor for modeling 2D puppet animations, with pen and touch input.
What Umamo is
Umamo is a cross-platform editor for modeling 2D puppet animations, with pen and touch input. It reads and writes Live2D Cubism .cmo3 and .moc3 files, supporting up to Cubism 5.4, and can export .uma, .cmo3, and .moc3 formats. It imports layered Krita (.kra), Photoshop (.psd), and Clip Studio Paint (.clip) artwork; Clip Studio Paint support is partial and has known blending issues. The editor has a resolution-independent interface, customizable key bindings, and a command registry. Desktop builds are available for Windows, macOS, and Linux, and the software is free and open source under GPL-3.0. The maker describes it as alpha-level software and recommends backing up project files. Animation itself is not supported yet, though it is described as a long-term goal. Listed minimum requirements are 16 GB of memory and a 4-core CPU. Android tablet builds are in progress. The Apple Silicon app is signed and notarized, Linux RPM and checksum files are signed with the Umamo release key, and Windows builds are not signed yet. Users can report format problems through GitHub issues.
