Build data flow diagrams (DFDs) in Raltey
Describe a system and Raltey drafts a leveled data flow diagram (context, 0, 1, 2) with external entities, processes, data stores, and labelled flows on the canvas.
What you can do
Built for data flow diagrams that ship.
- Context, level 0, level 1, level 2 diagrams.
- Standard DFD notation.
- Decompose a process into a sub-diagram.
Try these prompts
Type, paste, done.
1.DFD for an order processing system: customer → order → inventory → fulfillment.
2.Decompose the order process into a level-1 DFD.
How it works
From prompt to data flow diagram in three steps.
- 01
Describe the system
List the external entities and main processes.
- 02
Refine the levels
Decompose processes into sub-diagrams.
- 03
Export
PNG, SVG, or PDF.
Who uses it
- System analysis
- Compliance documentation
- Threat modeling input
Why Raltey for this
- Level-0 and level-1 stay in sync as you edit.
Frequently asked
