Spec score 7.6 #15 of 25 in VTuber Software

What it is

OpenVT is free, open-source software for 2D Vtubing, with native Linux desktop support as a stated priority. It imports Live2D avatars and works with OpenSeeFace, which requires a separate executable, or with VTubeStudio over Wi-Fi TCP. Transparent windows support alpha-based capture in OBS without a virtual camera or direct framebuffer access. Adjustable filtering can sharpen pixel-art model scaling, and multi-window popout controls provide separate control windows. Models can be shared with VTubeStudio without changing their files, while OpenVT keeps its own settings separate to avoid naming collisions. The project is built in Godot using open-source solutions and targets VTubeStudio feature parity, excluding complex features such as plugin compatibility and VNet. Precompiled itch.io builds are offered nightly when changes occur, though they are not guaranteed stable. OpenVT is available on Linux under a free plan listed as free, billed as “Name your own price.”
