NetLagLab

NetLagLab is a desktop app (traditional + AI) that lets game developers simulate real-world network conditions—latency, jitter, packet loss, bandwidth caps, NAT types—and record how their multiplayer game actually behaves. Instead of guessing, teams can run repeatable “network scenarios” locally or on a small cloud runner, capture timelines (RPCs, state sync, reconciliation, prediction errors), and export bug reports with repro steps. An AI assistant summarizes traces into likely root causes (e.g., unreliable channel misuse, snapshot size spikes, server tick drift) and suggests targeted experiments, not magical fixes. The goal is to make multiplayer QA less expensive and less hand-wavy, especially for small studios that can’t maintain a full network test lab. Integrations focus on Unity, Unreal, and Godot via lightweight SDK hooks and log format adapters so teams can start seeing value in a day.
