Design Software Architecture With Diagrams

Get the architecture a senior architect would sketch for your team: the options, the one to pick and why, and diagrams you can edit, in minutes instead of a week of meetings.

What it does

• Designs services, APIs, data, integrations and infrastructure around your real constraints: traffic, team size, budget, compliance
• Weighs two or three options and recommends one, with what would make it wrong
• Draws context, container, sequence and deployment diagrams in Mermaid or Excalidraw, rendered and editable
• Designs authentication, authorization and audit for users, services and AI agents
• Builds small throwaway spikes to prove a risky idea before you commit to it
• Finds what slows your app down and ranks the fixes by impact

What you need

• Nothing to start: describe your product or the change you are planning
• GitHub, to design from the code you already have (other code hosts work too)

How setup works

A first design with its diagram arrives in the first minutes. Along the way it learns your stack, your team and your constraints, then reads your repository and draws your current architecture.

What stays in your hands

• It never pushes to a shared branch or touches production; spikes stay in its sandbox or a branch you name
