Multiplayer, a debugging agent to run locally next to your coding agent

Multiplayer is a local debugging agent that sits alongside your coding agent, providing full-fidelity, unsampled traces and cross-service context that existing observability stacks fail to deliver. Built for developers and AI-assisted coding workflows, it solves the problem of debugging complex distributed systems by eliminating the gaps caused by sampling, aggregation, and service-boundary limitations. Its key innovation is giving AI agents the same rich, continuous data a human debugger would need, enabling more accurate root-cause analysis without leaving the local development environment.
