QA engineers, developers, and performance testers use PerfDog to identify and resolve performance bottlenecks across mobile, PC, and console platforms. Developed by Tencent WeTest, it monitors 200+ real-time metrics — FPS, CPU, GPU, memory, battery, thermal, network, and proprietary indicators such as Jank, Stutter, Smooth Index, and FPower (per-frame energy) — on Android, iOS, Windows, macOS, PlayStation, Xbox, Nintendo Switch, and VR. No ROOT, jailbreak, or SDK embedding required. CPU impact stays below 1%, preserving a native testing environment reflecting actual user conditions. Core capabilities: — GPU counters for Qualcomm, Mali, PowerVR, and iOS GPUs with utilization, pixel throughput, overdraw, and bus bandwidth — Engine Mode for Unreal Engine and Unity with CPU scheduling, thread inspection, and rendering analysis — Systrace Mode for Android event tracing with timeline heat maps — Weak network simulation with configurable latency, jitter, packet loss, and bandwidth — Custom Data Extension for real-time sync of app-specific metrics via socket API PerfDogService exposes gRPC APIs for automated multi-device parallel testing in Python, C#, C++, Java, PHP, and Go with CI/CD integration. Cloud dashboard provides visualization, comparison, and team collaboration. Over 200,000 apps tested with 20M+ sessions worldwide.
