Dev teams need ad-hoc screen sharing without account requirements or complex setups. Existing tools are either enterprise-focused or lack privacy controls.
Build a self-hostable webRTC solution with one-click rooms, keyboard/mouse sharing, and basic annotation tools. Focus on low-latency performance for pair programming.
Monetize through hosted instances for teams, or premium features like session recording and integrations.
MVP could be a single-page web app with shared cursor control and chat.
Biggest risk: WebRTC is crowded, differentiation needs to be crystal clear.
