Graphyn

Kotlin Multiplatform workflow editor library — build visual node-graph editors for Android, Desktop, Web, iOS, and Server using a single shared codebase.

Highlights

  • Canvas with pan, zoom, and drag — powered by Compose Multiplatform
  • MVI state management via dispatch(GraphynEditorIntent)
  • Plugin-based node and panel registry
  • Connection type validation with WorkflowTypeCompatibility
  • Undo / redo, multi-select, copy / paste, palette search
  • Node execution state badges (Running, Success, Error)
  • Maven Central artifact + iOS XCFramework
