SkelForm vs VTube Studio

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.

VTube Studio is an app for Virtual YouTubers to animate Live2D models. It runs on Android, iOS, macOS, and Windows, with face tracking through a webcam or iPhone, including eye tracking and winking. Webcam-based hand and gesture tracking can activate expressions and animations. Scene controls include hotkeys, microphone lip sync, animated PNG props, and visual post-processing effects. Users can attach images, animations, and customizable Live2D props to a model, with tracking and hotkeys available for control. Twitch integration lets viewers trigger hotkeys through emotes, redeems, subscriptions, and chat commands. Developers can use the VTube Studio API to make plugins that control models or trigger animations and expressions. VNet lets Steam friends collaborate on Windows and macOS, with up to six people per session; it requires launching through Steam and the separate $19.99 VNet DLC. The free Steam app shows a webcam-tracking watermark; removing it costs $14.99 once. iOS requires Face ID or an Apple A12 or newer chip, and Android requires Google ARCore support.
