Core Feature

Visual Node Editor

Build complex automation workflows by connecting nodes on a visual canvas. No coding required — if you can draw a flowchart, you can automate anything.

  • Drag-and-drop node placement with snap-to-grid
  • Real-time execution visualization and debugging
  • Multiple execution paths with conditional branching
  • Variable passing between nodes with type inference
  • Undo/redo history for every action
