PSPDFKit Instant consists of two parts: the Server backend, and the client frameworks. The PSPDFKit Server backend manages authentication and synchronizes documents and annotations. The PSPDFKit Instant mobile and web frameworks integrate into your app and communicate with the Server backend.


Connect to PSPDFKit using our iOS, Android, and Web frameworks, along with the PSPDFKit plugin for Flutter. Enabling Instant is a simple matter of adding the framework to your app.

PSPDFKit Server runs within a Docker container and provides a JSON-based API for easy integration with your existing infrastructure. It handles syncing documents and annotations automatically.
