SightRadar is a face recognition API for teams that need face search, verification and detection at scale, without AWS Rekognition's pricing. It is Rekognition-compatible: point the AWS SDK (boto3 and others) at SightRadar's endpoint and your existing code keeps working.
What you get:
Face search: find one person across thousands of photos from a single selfie (event photos, media libraries, photo delivery)
1:1 verification: compare two faces with a similarity threshold you choose
Face detection with confidence scores you can threshold on
Rekognition-compatible API: CreateCollection, IndexFaces, SearchFacesByImage, CompareFaces, DetectFaces and more
Photos with no faces return valid empty results, not errors
