Live2D Cubism vs SkelForm

Live2D Cubism Editor turns drawn illustrations into animated 2D models, with tools for shaping expressions through mesh deformation, physics, and lip sync. Live2D says its technology is used in mobile apps, console games, VTuber streaming, and animation. The editor runs on Windows and macOS, including Apple Silicon and Intel Mac versions, and exports PNG, JPEG, GIF, MP4, WebM, MOV, MOC3, model3.json, and motion3.json files. Editor files are supported by nizima LIVE and other third-party applications; Live2D also provides an After Effects plug-in and Photoshop scripts. The PRO trial lasts 42 days, after which the Editor continues as the FREE version. FREE is limited to one 2048 px texture file, 100 ArtMesh, 30 motion parameters, 50 deformers, and 30 parts; exceeding those limits prevents saving. FREE commercial use is restricted to General Users and Small-Scale Enterprises with annual sales under 10 million yen. Cubism PRO for indie is listed at $13.26 a month.

SkelForm is a free 2D skeletal animator designed for game animation. It offers a web editor that works without a download, as well as desktop availability for Linux, macOS and Windows. Listed animation features include styles, inverse kinematics and mesh deformation. SkelForm can import Photoshop Document files to build an armature: PSD groups become bones, while layers inside each group are combined into a texture. Exports include sprite sheets and video. A runtime is required to use SkelForm animations in games; the site lists generic and engine runtimes, and its guide covers using animations in pygame. The installation guide describes the downloaded editor as a portable program without an installer, while the v0.8 release lists dedicated Windows and Mac installers. SkelForm and its documentation are works in progress. Mobile development is inactive, with no direct mobile build process; the described option is to use the web version in a WebView wrapper. Its public repository lists a GPL-3.0 license.
