OpenVT

What OpenVT is

OpenVT is free, open-source software for 2D Vtubing, built with Godot and open-source solutions. Its project gives Linux desktop support top priority and describes native Linux support as a distinction from alternatives. It supports two tracking routes: OpenSeeFace, which requires a separate executable, and VTubeStudio over Wi-Fi TCP. Transparent windows support alpha-based capture in OBS without a virtual camera or direct framebuffer access. Adjustable filtering can make pixel-art models scale more sharply, and multi-window popout controls offer another way to operate the software. Models can be shared with VTubeStudio without changes to their files, while OpenVT-specific settings remain separate to avoid naming collisions. The project aims for feature parity with VTubeStudio, excluding complex capabilities such as plugin compatibility and VNet. The repository is marked MIT-licensed, although Live2D rendering depends on the copyrighted Live2D Cubism SDK. Precompiled itch.io builds are provided nightly when there are changes, but their stability is not guaranteed. On Linux, system-wide keyboard input while the window is unfocused depends on the godot-keylogger extension; some distributions may also require the user to be in the libinput group. The maker directs discussion, bug reports, and contributions to GitHub.

Who it suits

OpenVT suits Linux users who want an open-source tool for 2D Vtubing and OBS alpha capture. It may also fit people using VTubeStudio models or tracking, provided they can work within its Linux-focused feature set.

Limits

OpenVT is offered as a free plan. Nightly precompiled builds are not guaranteed to be stable; some Linux setups require the godot-keylogger extension and libinput group membership for system-wide keyboard input while the window is unfocused.

Getting started

1. Visit the OpenVT GitHub project.
2. Download a Linux build; precompiled itch.io builds are provided nightly when there are changes.
3. Set up OpenSeeFace separately if using that tracker, or connect to VTubeStudio over Wi-Fi TCP.
4. Configure tracking and controls.
5. For unfocused system-wide keyboard input, use the godot-keylogger extension; some distributions require libinput group membership.
6. Use GitHub for discussion, bug reports, or contributions.

Verdict

Linux-focused 2D Vtubers looking for free software and transparent OBS capture should consider OpenVT. Look elsewhere if you require plugin compatibility, VNet, or a virtual camera workflow.
