When to use it
Use to show who talks to whom and in what order, such as an API call, a login or payment flow, or a handoff between teams, with up to fourteen messages between two to six participants. Not for components that only depend on each other without an order (use the dependency graph), a request's path through hops, decisions, or states, and not for a participant messaging itself.
Adjust after generating
Change the style, colors, and font, and these options, as often as you like without spending credits.

Architecture: system contextA C4 system context diagram, a "who uses it and what it depends on" slide, or an integration overview: one system, one to four actors that use it, and one to five external systems it calls or that call it, each link saying what it does.
Architecture: dependency graphThree to twelve components that call or depend on each other with no fixed tiers, such as a microservice call map, a service dependency graph, or data lineage between systems, with links labeled by protocol or what flows (gRPC, REST, events).
Architecture: environmentsOne system shown as two to four copies that are compared side by side: dev, staging, and production environments with promotion between them, region A, region B, and disaster recovery with replication, or blue and green stacks.
Architecture: event hubEvent flows through one broker, bus, or topic hub with one to five producers and one to five consumers, such as Kafka topics, Google Pub/Sub, SNS fanning out to SQS queues, EventBridge rules, or a webhook gateway delivering to several handlers; built for fan-in and fan-out.
Architecture: grouped panels left to rightTwo to fourteen components placed in two to five networks, clusters, subnets, or accounts, such as an AWS VPC with public and private subnets or a Kubernetes cluster with namespaces, optionally inside one region with users or third-party services outside.
Architecture: isometric floating layer plates stacked with a clear gapA layered system where components rely on specific components in the layer directly below: software layers from experience through services to data, an operating model from strategy through operations to delivery teams, or a data stack from reports through warehouse and pipelines to sources.
