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.

Liveness Detection

ARSA includes both passive and active liveness with every plan. Azure's liveness features are more limited.

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.
