An architecture builder that's simple for company owners to design and build software systems—focusing on clarity, collaboration, and progressive detail.
High-level business purpose and external actors
Applications, data stores, microservices
Logical modules inside containers
Classes, functions, or files
Software architecture is best understood in layers. The C4 model describes systems at four levels—letting you start high-level and zoom into specifics only when needed.
A high-level view showing the software system in the context of users and external systems. Start here to align business and technical teams.
Shows the major building blocks: web app, mobile app, database, external APIs. Decide on cloud vs. on-premise, monolith vs. microservices.
Drill into each container to define internal components. Click to zoom into deeper layers without creating separate diagrams.
Optional for early design. Shows actual classes, functions, or files when you need implementation-level detail.
Progressive detail—zoom in only when needed
Everything you need to design, document, and share your software architecture—all in one place.
Intuitive canvas with draggable components. No coding required—just design visually and see your architecture take shape.
Built on the industry-standard C4 framework. Start with context, drill into containers and components as needed.
Work with your team in real-time. Share diagrams with stakeholders and keep everyone aligned.
Export your diagrams as PNG, SVG, or JSON. Integrate with documentation tools and presentations.
Support for microservices, APIs, databases, message queues, and complex integration patterns.
Track changes over time. Restore previous versions and maintain architecture documentation.

See what company owners and technical leads are saying about our architecture builder.
"As a non-technical founder, I finally understand our system architecture. The C4 model approach makes it so accessible."
"We use this tool to align our business and engineering teams. The visual approach has transformed our architecture discussions."
"The export feature is a game-changer. We include diagrams in our stakeholder presentations and they're always up-to-date."
Your architecture tool shouldn't just visualize systems—it should accelerate delivery. Here's how we help companies turn diagrams into deployed software.
Analyze designs to estimate development months, required roles, and complexity flags. Signal implementation effort automatically.
Generate "Request for Proposal" documents automatically. Turn designs into firm quotes with one click.
"Designed it here? Build it with us at 10% off." Reduce friction by maintaining a single source of truth.
Show case studies inside the tool. "Reduced time-to-market by 40%" builds trust at decision moments.
Offer official "Validated by Our Architects" reviews. It's a soft entry to full engagement.
"Based on 500 similar projects, this design typically encounters..." Data-powered risk mitigation.
You're not selling a design tool. You're selling confidence and reduction of execution risk. The tool helps users visualize their system—your company helps them realize it.
Make the transition from design to build feel like a natural, safe, and obvious next step.
Start building your software system visually. No signup required to try it out.
Your diagrams are automatically saved
Double-click node to configure
Extend and customize the architecture builder with these powerful injection methods
Open DevTools (F12) → Console tab. Paste JavaScript to manipulate the diagramming interface.
const diagram = window.diagramApp;
diagram.addNode({
id: 'custom-node',
label: 'Injected Node',
type: 'service'
});Create a custom extension with content scripts for persistent UI modifications and automated workflows.
Use Tampermonkey or Greasemonkey to inject custom logic that runs automatically on page load.

const originalSave = diagram.save;
diagram.save = function(...args) {

};Run a local proxy to modify JavaScript/CSS before it reaches your browser. Advanced but powerful.
Node-level diagramming supports multiple languages. Customize labels and annotations per locale.
