Instant Sync and Collaboration
PSPDFKit Instant is our prebuilt solution for synchronizing annotations across multiple concurrent users, devices, or sessions. It offers developers a self-hosted solution that handles document viewing on any platform, data management, conflict resolution, version tracking, diffing, and merging. It’s a licensable component that’s included as part of PSPDFKit Server.
