Zero-lag pair programming via direct P2P code syncing.
Remote developers are frustrated with laggy real-time code collaboration tools that make pair programming sessions unproductive.
PairBeam uses WebRTC for peer-to-peer code editing, eliminating server relay latency during live sessions. Developers share editable code cursors and changes instantly without buffering. Sessions auto-resolve conflicts using CRDTs for seamless collaboration.
