Sprout renders any Spout2 source — VTube Studio, your camera, anything — as a transparent, GPU-accelerated overlay that stays on top while you game, work, or stream.
Features
Lightweight, single-file executable. No install wizard. No background services eating your RAM.
Mouse events pass straight through the overlay so you can interact with games and apps behind it without moving anything.
Direct3D 11 rendering at up to 60 FPS with configurable targets (15 / 20 / 24 / 30 / 60) to match your needs.
Assign each overlay to any connected monitor. DPI-aware so it looks crisp on mixed high-res setups.
Trim pixels from any edge (top, bottom, left, right) to position your avatar exactly where you want it.
The overlay gently fades out when your cursor moves over it, revealing whatever's beneath with a smooth animation.
Save your full configuration as a named preset and switch between setups instantly — great for different stream scenes.
Bind keys to hide all overlays or quit the app — they fire even when Sprout isn't the focused window.
Control every setting remotely from a Stream Deck, web dashboard, PowerShell script, or any HTTP client.
Display multiple Spout sources simultaneously with independent settings and Z-order control for complex layouts.
