VISUAL SYSTEM DESIGN & SIMULATION

Run your architecture before you build it. Map your existing architecture with MCP. Share how your system works.

Graphrun turns system diagrams into runnable models. Design a new system or map your codebase, test success and failure paths, and share runs your team can replay.

Timeline

User cache looked up user:42 and missed. T1 follows the miss route.

Illustrative timings.

Example: follow a cache miss from API to database, then replay each event.

One model, multiple lenses

Design

Connect services, APIs, events and data.

Map

Bring existing architecture in with MCP.

Simulate

Test success, retry, timeout and failure paths.

Change

Explore a change before touching production.

Present

Share a guided story with replayable evidence.

MCP / REPOSITORY INTELLIGENCE

Start with the code you already have.

Connect your coding agent through MCP to trace services and code flows. With guarded editing, it can draft a model and journeys for your review.

MCP cannot publish your work or create share links.

Set up MCP
Code → model → journeys

Make your next architecture decision with a runnable model.
