Sequence Diagram Builder

Generate UML sequence diagrams using sequencediagram.org text syntax.

Quick Start

Create a sequence diagram by:

1. Gather requirements about the interaction flow to visualize
2. Define participants (actors, systems, databases, etc.)
3. Map out the message flow between participants
4. Add conditional logic, loops, and notes as needed
5. Generate a .txt file with the diagram syntax

Output Format

Always save diagrams as .txt files. The user can open these files at https://sequencediagram.org to view and export to various formats (PNG, PDF, SVG).
