A SYSTEM DESIGN WORKBENCH

Make the invisible
architecture visible.

Map components, trace dependencies, define system boundaries, and document architecture decisions.

THE IDEA

Architecture is more than boxes and arrows. System Lab helps you explain what exists, how it connects, and where the risk lives.

BUILT FOR THINKING IN SYSTEMS

From rough sketch
to shared blueprint.

Turn a rough sketch into a useful system map. Clarify dependencies and export a specification for review.

01 / MAP

Compose the system

Add clients, APIs, services, workers, event flows, and external systems. Describe the system’s scope and purpose.

02 / TRACE

Make dependencies explicit

Label each connection with its direction, protocol, and purpose.

03 / REVIEW

Review the shape

Check for orphan components, missing descriptions, duplicate names, broken references, and connection issues.

04 / SHARE

Export the blueprint

Export project JSON, Mermaid, Markdown, or SVG files. No account or cloud workspace needed.

A DELIBERATE WORKFLOW

Think clearly.
Connect precisely.

Move from an early sketch to useful documentation, and revise the map as decisions change.

Open the workbench
  1. 01

    Begin with an empty canvas

    Start with a blank canvas, choose a template, or import an optional sample map.

  2. 02

    Add components and describe them

    Name each component, choose its role, record ownership and criticality, and write down its purpose.

  3. 03

    Connect, review, and refine

    Trace dependencies, rearrange the map, use structural findings to spot omissions, and produce a clear architecture document.

  4. 04

    Export a portable source of truth

    Download the project JSON and the diagram or documentation formats you need to continue the work elsewhere.

PRIVACY & EXPORTS

Your map stays in your hands.
