InsightFace is a comprehensive, production-grade face analysis ecosystem. It provides a Python package (`insightface`) with high-level APIs for face detection, recognition, attribute estimation, and face swapping, backed by ONNX Runtime. A C++ SDK (`inspireface`) enables on-device inference across Linux, Android, iOS, and embedded platforms with support for CUDA, TensorRT, CoreML, and Rockchip NPUs. A FastAPI server offers REST endpoints for face search and verification with SQLite persistence and license management. A PySide6 desktop GUI (Evaluation Studio) provides interactive workflows for verification, album management, and enterprise evaluation. The repository also contains extensive research code for training face recognition models (ArcFace, Partial FC, VPL) across PyTorch, MXNet, OneFlow, and PaddlePaddle, as well as detection (SCRFD, RetinaFace), 3D reconstruction, and face parsing. While the core application components are well-engineered and actively maintained, the research subprojects vary in maturity and may rely on outdated frameworks.
