Pasteboard Viewer is a free, open-source developer utility designed for inspecting system pasteboard contents on Apple devices. It helps programmers examine data copied or shared through the NSPasteboard and UIPasteboard APIs. The application displays available pasteboard items and their associated data types in an organized interface. Its contents refresh automatically when the system pasteboard changes. Users can preview plain text, rich text, images, and other formats supported by Quick Look. It also provides access to pasteboard type identifiers for debugging application interoperability. The macOS version supports an always-on-top window and keyboard navigation between items. Available for macOS, iOS, and visionOS, Pasteboard Viewer focuses on debugging rather than maintaining clipboard history.
