Degraded path
Reservation and fulfillment
Inventory Service and Order fulfillment consume OrderPlaced before stock can be committed.
For teams and their AI agents
See the system before you change it.
Your team is building faster. Keep the architecture understandable. Archflow connects your systems, workflows, data, and decisions in a shared model, so your team and AI agents can explore how things work and reason through what comes next.

Archie in context
Ask the architecture. Work the evidence.
Archie reads the same example model, follows the behavior behind a question, and opens the result beside the conversation so the reasoning stays inspectable.

Order Service · Current architecture
What would break if checkout stopped publishing OrderPlaced?
I’ll trace the event from checkout and separate direct impact from paths that remain isolated.
- Reading Order Service
- Following OrderPlaced
- Comparing affected paths
Inventory reservation and fulfillment status would degrade. Payment authorization remains available because it does not consume the event.
I opened the trace and a focused recommendation in the Workbench.

Payment authorization
Payment Service is called synchronously before the event and remains available.
Recommendation
Preserve the event contract or introduce an explicit inventory reservation fallback before removing the publisher.
Four ways to work with Archie
Move from inspection to decision without switching tools or surrendering review.
01
Exploration
Explore in place
Traverse systems, workflows, events, capabilities, data, and deployments without losing the project context behind the answer.
- Read-only
- Source-linked
02
Workbench simulation
Simulate the change
Model structural and workflow changes against a candidate version. Compare the impact while the baseline remains untouched.
- Candidate model
- Blast radius
03
Story mode
Tell the system story
Turn the selected architecture into a guided, evidence-backed narrative that meets each audience at the right level of detail.
- Guided narrative
- Read-only
04
Full edit and co-working
Change it together
Let Archie draft model and documentation edits while you review, revise, apply, or undo every durable change from the Workbench.
- Human review
- Durable changes
Beyond the diagram
Architecture becomes useful when every layer can answer back.
A topology tells you what exists. Archflow connects it to how the system behaves, where pressure accumulates, what a change can touch, and how the decision should be communicated.
01
Model the whole estate
Build the C4 hierarchy, then connect data boundaries, capabilities, deployment environments, and ownership without flattening the system into boxes and arrows.
- Systems and containers
- Data and capabilities
- Deployment topology
02
Connect structure to behavior
Keep event models and workflows attached to the systems that produce, move, and consume behavior. The runtime story stays navigable from the architecture.
- Event models
- Workflow orchestration
- Synchronous and async flow
03
Read architectural pressure
Turn relationships into usable signals. Complexity and coupling reveal where change is expensive; blast radius shows what a failure or decision can reach.
- Complexity lenses
- Coupling analysis
- Blast radius propagation
04
Explain the decision
Carry model evidence into recommendations, Architecture Documents, the project Handbook, and published views that different stakeholders can actually use.
- Reviewable recommendations
- Living documentation
- Shareable architecture
One continuous operating loop
No handoff loses the architectural thread.
Move from inventory to impact to explanation inside the same project context.

Evidence, not ceremony
Every insight keeps its route back to the system.
AI helps inspect, draft, and challenge. The source material remains visible, editable, and reviewable by the people accountable for the architecture.
Architecture intelligence
Analysis stays tied to the topology it describes, so a warning can be traced back to the exact relationships, systems, and workflows behind it.
- Architecture fingerprint
- Complexity and coupling
- Blast radius and recommendations
Behavior in context
Events, workflow steps, data movement, and deployment boundaries become part of the same system story instead of separate specialist artifacts.
- Event models
- Workflow traces
- Data and deployment evidence
Living communication
Architecture Documents, the project Handbook, public minisites, and reference cards evolve beside the model and remain ready for review.
- Architecture Documents
- Architecture Handbook
- Published views and cards
