Key Differences
Access
Azure Face API now requires an application and approval process for face recognition features. ARSA has no approval gates — sign up and start immediately.

Pricing Simplicity
Azure uses complex per-transaction pricing. ARSA offers clear monthly plans starting at $29/month.
Self-Hosted Option
ARSA can be deployed on your own servers. Azure Face API is cloud-only.
Integration Example
# ARSA — simple, all-in-one curl -X POST "https://faceapi.arsa.technology/api/v1/face_recognition/recognize_face" \ -H "x-key-secret: YOUR_KEY" \ -F "face_image=@photo.jpg" # Returns: recognition + liveness + age/gender
Verdict
Choose Azure if you're an enterprise already using Azure extensively. Choose ARSA for simpler setup, complete liveness detection, self-hosted options, and transparent pricing.
