I’d love to share Choreo — a code-first toolkit designed to help map, visualize, and run metrics on your system architectures.

Choreo embraces the idea of architecture as data. You describe your workflows, pipelines, or data paths declaratively in Elixir, and Choreo builds them up using Yog underneath.

You get both customizable Graphviz DOT layouts, and utilize the built-in architectural validation and analysis.

Supported domains out of the box:

• Finite State Machines (Choreo.FSM): Trace state transitions, detect terminal dead-ends, and identify unreachable states.
• Workflows (Choreo.Workflow): Map out critical execution paths, identify latency bottlenecks, and verify Saga pattern constraints (e.g. ensuring compensation paths safely reach termination targets).
• Data Pipelines (Choreo.Dataflow): Simulate backpressure scenarios, measure stage constraints, and flag unhandled error branches.
• Dependency Trees (Choreo.Dependency): Unpack cyclic bottlenecks, clean transitive bloat, and compute Uncle Bob’s structural Instability Metrics.
• Threat Models (Choreo.ThreatModel): Run stride evaluations automatically over mapped vectors.

Quick Example:

alias Choreo.FSM

fsm =
  FSM.new()
  |> FSM.add_state(:cart, initial: true)
  |> FSM.add_state(:processing)
  |> FSM.add_state(:completed, final: true)
  |> FSM.add_state(:failed, final: true)
  |> FSM.transition(:cart, :processing, "checkout")
  |> FSM.transition(:processing, :completed, "success")
  |> FSM.transition(:processing, :failed, "error")

# Export stunning diagrams with theming
IO.puts FSM.to_dot(fsm, theme: :dark)

I am actively working with it and bug-fixes will be made, and new features will be added frequently.
