OpenVT
What it is
OpenVT is free, open-source software for 2D Vtubing with native Linux desktop support as its main priority. It can use OpenSeeFace tracking, which requires a separate executable, or connect to VTubeStudio over Wi-Fi TCP. Live2D models can be shared with VTubeStudio without changing their files, while OpenVT keeps its own settings separate. Transparent windows support alpha-based OBS capture without a virtual camera or direct framebuffer access. Adjustable filtering helps scale pixel-art models, and multi-window popout controls provide additional operation options. The project is built in Godot with open-source solutions and aims for VTubeStudio feature parity, excluding complex features such as plugin compatibility and VNet. Nightly itch.io builds may be unstable. Linux-wide hotkeys while unfocused depend on godot-keylogger, and some distributions require libinput group membership. The repository is MIT-licensed; Live2D rendering uses the copyrighted Cubism SDK.
For and against
For
- Native Linux desktop support is a top priority
- Supports Live2D model sharing with VTubeStudio
- Enables transparent-window OBS capture
- Offers adjustable pixel-art filtering
- Provides multi-window popout controls
Against
- Nightly builds are not guaranteed stable
- OpenSeeFace requires a separate executable
- Plugin compatibility and VNet are excluded
- Unfocused Linux hotkeys need an extension
The verdict
OpenVT offers a Linux-first, open-source route for 2D Vtubing with Live2D, tracking, and OBS-friendly windows. Users should account for nightly-build instability and Linux-specific hotkey setup.
Who it suits
OpenVT suits Linux users creating 2D Vtuber content with Live2D models, OBS capture, and supported tracking options. It also fits users who prefer open-source, community-driven software.
