A bridge between your live stream and your stream setup.
Build Events that listen for live stream activity, then trigger Actions that make your stream feel interactive.
🎁
Gift and viewer interactions
Create special responses for gifts, follows, likes, shares, chat commands, and specific viewer rules.
🖥️
Stream overlays
Use capture-ready overlay windows for OBS and TikTok Live Studio, including goals, gifts, wheels, and effects.
🔊
Local TTS and audio tools
Use local/offline TTS workflows and audio Actions without relying on cloud servers for core playback.

Foundation work is being added for controller simulation, game control, and more advanced action types.
🧩
Built for expansion
Hollow Bridge is designed to grow into more platforms, more overlays, and more creator-focused modules over time.
Platform support
Built around streamers, not just one platform.
Hollow Bridge currently focuses on Twitch and TikTok live streaming workflows, including chat, gifts, commands, and stream automation. Future updates are planned to expand support to additional live platforms.

Chat, commands, stream automation, and creator tool integration.

In development
Voice Changer and RVC foundation.
Hollow Bridge now includes early foundation work for a built-in Voice Changer and RVC testing path. This system is not fully functional yet and is still being developed.
Now
Voice Changer tab foundation
Global enable/disable, device selection, test controls, and early effect settings.
In progress
RVC test workflow
Testing tools for installed RVC voices, CPU/GPU selection, F0 options, and saved test output.
Planned
True live RVC conversion
Low-latency live microphone conversion for stream routing and virtual audio workflows.
Song requests
Creator-controlled music request tools.
Hollow Bridge includes a Songs system for managing stream song requests, queues, overlays, and playback controls. Recent work improves startup behavior so the Songs backend only starts when needed.
Designed for safer stream control
Use command settings, queues, role options, and manual controls to keep the streamer in charge of playback.
