Start from a real brief
Open a system prompt with users, constraints, scale targets, and product behavior already framed.
Guided practice01
ArchOS
Draw the system, prove the flow, review the tradeoffs, and publish the decision.
Build realistic architecture diagrams, simulate the flows that matter, collect review feedback, and leave with a decision record that sounds like engineering judgment.
Components
ClientGatewayServiceSQL DBQueueWorker
Draw
Start from a blank architecture canvas.
Correct flow
Scenario-aware review
Order is committed before checkout returns.
Receipts move async so the hot path stays fast.
Practice workspace
Build the system, prove the flow, keep the decision.
ArchOS keeps the prompt, canvas, simulation, review, and version history in one loop so architecture practice turns into durable judgment.
Model the architecture
Place clients, gateways, services, stores, caches, queues, and workers on a canvas built for system design.
Visual workspace02
Run the request path
Simulate the happy path, async work, fallbacks, and bottlenecks so a diagram becomes a working design.
Scenario checks03
Keep the work
Save attempts, restore older versions, and keep a decision trail for designs you can explain later.
Saved progress04
Review with context
Share read-only designs, collect scoped comments, and keep feedback connected to the architecture.
Review loop05
Collaborate when it matters
Use team canvases, roles, live presence, and version history when a design needs team input.
Team review06
Workflow
From rough idea to a design you can defend.
