Disconnected views
Architecture and sequence diagrams drift apart as soon as the system changes.
Living software architecture for modern engineering teams
One model. Every view.
Design software systems in one living model. Connect structure, behavior, collaboration, and design history—without redrawing the same system in separate tools.
Full access is free during early access. Every available feature is included. No credit card required.
Core modeling will remain free forever.
Order APISame system elements. One focused path.
One element, many contextsReuse the same component without creating conflicting copies.
Structure + behaviorSystem maps and feature flows stay connected.
Real-time collaborationDesign and review the same model together.
Safe design historySave checkpoints, compare changes, restore or branch.
Why another diagram doesn't work
Stop redrawing the same system.
Traditional tools turn architecture, sequence diagrams, and feature documentation into separate files. Every copy creates another version of the truth—and another thing your team has to maintain.

UnographOne connected model that stays consistent across every view.
Hidden assumptions
Retries, permissions, errors, and alternative paths remain unclear until implementation.
Lost decisions
Important design context disappears across calls, whiteboards, chat threads, and duplicate files.
One source of truth
Create once. Explore every view.
Create each system element once, reuse it across contexts, and use the same model to explain both what the system contains and how it behaves over time.
System structure
Feature flow
From idea to shared understanding
Design the change before implementation.
Turn a feature discussion into a model your team can review, preserve, and return to—without rebuilding the same context in multiple tools.
Start at the level the team needs. Drill into detail only where the change requires it.

Who it’s for
Everyone works from the same model
Each role explores the same architecture from its own perspective—without creating separate diagrams.
See the whole system before approving change.
Keep architecture understandable as your product and engineering organization grow.
Follow features without reading technical diagrams.
Understand delivery impact, dependencies, and affected services before development starts.
Model once. Never redraw the same architecture.
Trace services, dependencies, and runtime behavior from one living model.
Explain complex systems in minutes.
Present interactive architecture clients can explore instead of static documentation.
One model. Every view.
Map the next feature before code.
