SDK platform parity

Every Amba SDK method across Web, Node, React, React Native, Expo, iOS, Android, Flutter, and Unity — one generated matrix that cannot drift from the SDKs.

Every Amba SDK is built from a single method catalog — the same source of truth the SDKs themselves are built from. This page is generated directly from that catalog and the SDK sources, so it always shows what each SDK actually ships today: 136 methods across 34 namespaces, on nine platforms.

Legend

✓ — available on this platform today.
— — not available on this platform (not applicable, or not shipped yet).

Two columns are inherited by construction: React re-exports the full Web surface (@layers/amba-react is the hooks layer on top of @layers/amba-web), so its column always matches Web; Expo re-exports the full React Native surface plus Expo-only helpers (push token capture, native sign-in flows), so its column always matches React Native.

Method names are shown in their canonical dotted form (Amba.<namespace>.<method> on client SDKs). A few SDKs expose the same method under a platform-idiomatic name — for example, the Unity SDK uses PascalCase with an Async suffix (Amba.Collections.FindOneAsync), and some namespaces differ slightly per package (the Node SDK's server client scopes methods under client.asUser(id)). Availability is identical either way.

Not in this matrix

The matrix covers the per-method SDK surface. A few cross-cutting capabilities are documented on their own pages instead of as rows here:

Client lifecycle (Amba.configure) and event tracking (Amba.track).
Function invocation (Amba.functions.invoke).
Live updates — the realtime subscription builders (Amba.collection(name).subscribe(), Amba.gamification.subscribe()). The conversation realtime builder appears above as messaging.conversation.
The offline queue and optimistic-update helpers (Amba.offline).
Platform-specific extras such as Expo's registerPushToken() and the native sign-in conveniences described in each quickstart.

Picking an SDK

You're building…	Use
A web app (React or otherwise)	`@layers/amba-web` / `@layers/amba-react`
A server / backend job	`@layers/amba-node`
A bare React Native app	`@layers/amba-react-native`
An Expo app	`@layers/amba-expo`
A native iOS app	Swift SDK
A native Android app	Kotlin SDK
A Flutter app	Flutter SDK
A Unity game	Unity SDK

See the per-platform quickstarts for install and setup, and the feature docs for the shared API surface.
