Sequence Diagram Features

Clear visualization for complex system interactions

UML Standard Compliance
Diagrams follow official UML notation to ensure clarity and consistency.
Temporal Flow Clarity
Vertical timelines make message order and dependencies easy to understand.
Supports Many Participants
Visualize interactions across multiple services, components, or external systems.
Request/Response Modeling

Sequence Diagram Maker FAQs

What systems can I document with sequence diagrams?

API flows, authentication journeys, microservice interactions, user requests, backend processing, and nearly any time-ordered process.

Can I show async or event-driven operations?

Yes. Describe the async behavior and AI will represent it using appropriate UML arrow styles.

Is this suitable for API documentation?

Absolutely. Sequence diagrams are one of the clearest ways to visualize REST, GraphQL, or event-driven API flows.
