PerfDog, developed by Tencent WeTest, is a professional cross-platform performance testing and analysis tool designed for QA engineers and developers. It provides real-time monitoring of 200+ performance metrics — including FPS, CPU, GPU, Memory, Battery, Network, Jank, and Stutter — across mobile, PC, and console applications.
The tool functions without SDK embedding or device rooting, with less than 1% impact on device performance, allowing testing in a completely native environment. Beyond core metrics, PerfDog offers in-depth GPU counter analysis (Qualcomm, Mali, PowerVR, iOS), engine-level profiling for Unity and Unreal Engine, and weak network simulation — enabling teams to pinpoint performance bottlenecks using its proprietary Jank and Stutter detection algorithms.
PerfDog supports Android, iOS, Windows, macOS, PlayStation, Xbox, Nintendo Switch, and VR platforms. It includes a cloud-based dashboard for data visualization, team collaboration, and cross-device benchmarking. For automation workflows, PerfDogService provides gRPC-based APIs for multi-device parallel testing and CI/CD integration.
Trusted by 140+ major game studios and the world's top 10 smartphone brands, PerfDog has been used to conduct over 20 million performance tests worldwide.
