Multi-user steering for OpenCode sessions when screen sharing feels too heavy.

Strengths

•WebSocket relay keeps guest setup minimal; no API keys or installs needed.
•Solves terminal collaboration friction where screen sharing is laggy or privacy-invasive.
•Fits naturally into existing OpenCode CLI workflows without changing host environment.

Weaknesses

•Tied to OpenCode; useless if teams prefer Cursor, Copilot, or other agents.
•Early v0.1.0 lacks session history, access controls, or conflict resolution for prompts.

Post Description

My friends, colleagues, and I use AI coding agents almost daily with OpenCode. The problem is when someone needs help mid-session, you either share a screen or hover over their shoulder. There's no way to just jump in. This process reminded me a bit of 'rubberducking'.

I built Qwack to help solve this problem. One person hosts the agent and others join. Everyone shares the same context, sees the same output, and can send prompts to help steer the agent. The host's machine runs everything, the server is just a WebSocket relay.
