## What it is
An open-source face recognition SDK by Faceplugin providing face detection, landmark extraction, feature embedding generation, and face template matching via Python APIs. It runs fully on-premise on Windows and Linux, with optional GPU acceleration and no licensing fees.

## Use cases
- detect faces in images
- extract facial landmarks
- generate face embeddings from photos
- compare two faces for similarity
- build 1:1 face verification
- build 1:N face identification
- run face recognition fully offline on-premise

## When to choose
- you need free, on-premise face recognition on Windows or Linux
- you want a simple Python API for detection, landmarks, and matching
- privacy requires that biometric data never leaves your infrastructure
- you need CPU-only operation without mandatory GPU

## When to avoid
- you need liveness detection, deepfake detection, or ID document verification (commercial SDKs)
- you need mobile (Android/iOS) support from this repo
- you require a formal open-source license for legal/compliance reasons (no license file)
- you need a managed cloud face recognition API
