# SightRadar vs Azure Face API

> Microsoft gates the Azure Face API's recognition and identification features behind a Limited Access approval — you fill out an application and wait before you can verify or identify faces, and new resources still carry default transaction-per-second limits. SightRadar gives you the same core operations (detect, compare, search, index) on instant self-serve sign-up, with a real web console, ready-made SDKs, an AWS Rekognition–compatible API, and pay-only-for-what-you-use per-photo pricing at roughly half the cost ($0.00093/photo).

## Bottom line

On price, reliability, and the web UI, SightRadar is the clear winner: no Limited Access application or quota wait, roughly half the per-call cost with pay-only-for-what-you-use pricing, and a real console with per-operation cost visibility — on a Rekognition-compatible API. Choose Azure Face only if single-vendor Azure governance outweighs all of that.

## Headline verdicts

### Price — winner: SightRadar
- SightRadar: $0.00093/photo, pay only for what you use, no subscription — roughly half the typical Azure per-transaction cost.
- Azure Face API: Postpaid per-transaction tiers on the Azure bill; higher effective cost per call.

### Reliability & access — winner: SightRadar
- SightRadar: Instant self-serve. No Limited Access application, no approval wait, no default TPS gate.
- Azure Face API: Recognition/identification gated behind a Limited Access application; default per-second transaction limits on new resources.

### Web UI — winner: SightRadar
- SightRadar: A console to browse collections, run searches, see per-operation usage and cost, and manage keys.
- Azure Face API: Configured through the Azure portal/SDK; no dedicated face-collection browser or per-operation face-cost view.

## Where SightRadar wins

- No Limited Access gate: Azure makes you apply for recognition/identification and wait for Microsoft's approval. SightRadar is available the minute you sign up.
- Wider format support: SightRadar decodes JPEG, PNG, WebP, HEIC/HEIF, TIFF, GIF, and BMP natively. Azure Face accepts JPEG, PNG, GIF, and BMP — but not WebP or HEIC, so modern-CDN and iPhone photos need converting first.
- A 30 MB per-image byte ceiling versus Azure's 6 MB cap, and high-resolution photos are auto-downscaled before processing — so full-resolution phone and DSLR shots just work without manual resizing.
- Two-tier match results built for biometric privacy: every search match is labelled auto (high-confidence, safe to reveal) or review (plausible — show behind a 'confirm it's you' step). Azure returns one raw confidence score and leaves the wrong-reveal risk to you.
- Charge-safe retries: send an Idempotency-Key and a replayed call returns 409 before any charge, so a network blip never double-bills you — and every billable call reports your remaining balance in an X-Credits-Remaining header.
- No quota wait: new Azure Face resources carry default transactions-per-second limits; SightRadar has no default TPS gate to scale past.
- Roughly half the cost on a pay-as-you-go model — $0.00093/photo, no subscription, spend only what's in your wallet.
- A real web console for collections, searches, keys, and per-operation usage and cost — not just the generic Azure portal.
- Rekognition-compatible API plus zero-dependency Python and Node SDKs, so migrating off AWS is a one-endpoint change.

## Where Azure Face API is the better fit

- If you're deeply standardized on Azure and need first-party integration with Entra ID (Azure AD), the rest of Cognitive Services, and Azure governance/compliance tooling under one vendor, that native fit is the one area Azure leads.
