Get startedThe mental model — keys, credits, verdicts and warnings — in the order you meet them.

REST API

Server-to-server HTTP. The surface every SDK wraps — and the only integration with no SDK to install.

Web / TypeScript

@neetix/liveliness — the browser and Node client. Typed responses, typed errors, zero dependencies.

Quickstart

iOS / Swift

NeetixLiveliness — URLSession async/await client plus a SwiftUI guided-capture view. Live on Swift Package Manager.

Quickstart

Android / Kotlin

Kotlin client on OkHttp and coroutines, plus an optional CameraX guided-capture module. Live on JitPack.

Quickstart

Flutter / Dart

neetix_liveliness — a pure-Dart client that runs on mobile, web, desktop and server-side Dart.

Quickstart

React Native

A hook and file helpers over the same TypeScript core the web SDK uses.

Quickstart

On-device (WASM)

@neetix/edge — face detection and passive liveness running entirely in the browser. No API key, no network, no biometric transmitted.
