Models drift apart
Context maps, aggregates, and event flows live in slides, wikis, and code — rarely as one coherent picture.
dddesigner
Design complex systems as one connected architectural model
Every architectural decision stays traceable and coherent — from bounded contexts to events, sagas, and generated code.
The problem
Architecture fragments when teams scale
We talk about engineer problems, not feature lists. Features only prove the value.
Change gets expensive
Without a shared architectural model, every evolution risks breaking invariants no one can still explain.
Decisions lose their trail
Architects need quality, evolution, and consistency. Untraceable choices raise the cost of every next release.
The approach
One connected model — not another diagram tool
dddesigner keeps strategy, tactics, and delivery linked in a single architectural model.
Context & aggregates
Bounded contexts, aggregates, commands, events, and policies on one canvas.
Processes & flows
Sagas and event-flow swimlanes that stay tied to the same domain model.
Ship from the model
Generate production-oriented code and export diagrams when the design is ready.
AI, with guardrails
AI accelerates delivery. The model keeps it coherent.
We do not pit people against AI. Architectural models let teams use AI consistently and safely — the architect stays in charge of the system shape.
Who it is for
Software architects
Design the system as one connected model. Keep every architectural decision traceable and aligned.
Tech leads & engineering managers
Lower architectural risk, give the team a shared language, and speed up decisions that used to stall in meetings.
