# Dfns SDKs

> Official Dfns SDKs for backend languages and frontend platforms, including TypeScript, Python, Java, Go, Swift, Kotlin, Flutter, and React Native.

export const SupportLink = ({children}) => {

};

Dfns SDKs handle [request signing](/api-reference/auth/signing-flows) and provide typed access to the Dfns API. You can always develop directly against the API, but SDKs accelerate development by handling the authentication complexity for you.

## Backend SDKs

Server-side SDKs for service accounts, backend services, and server-to-server integrations. These handle private key signing and provide full API access.

## Frontend SDKs

Client-side SDKs for web and mobile applications. These handle passkey-based signing on the user's device and work together with a backend using [delegated signing](/sdks/backend#delegated-signing).
