Design systems. Understand every decision.
Practice system design on a visual canvas. Build an architecture, explain your trade-offs, review your assumptions, and improve your next iteration.
What is Diagramwise?
Diagramwise is a system design practice tool. You pick a realistic problem, build the architecture on a visual canvas, explain your assumptions and trade-offs, and receive structured feedback on scalability, reliability, and data design so you can improve the next iteration.
Build, review, and improve your architecture
- Make the request path visibleStart with a clear architecture and show how each component connects.
- Explain the trade-offsReview assumptions around scale, reliability, latency, and data design.
- Improve the next iterationTurn structured feedback into a stronger design you can defend.
Frequently asked questions
What is Diagramwise?
Diagramwise is a web-based system design practice environment. It combines an interactive architecture canvas with realistic problems, learning paths, and structured design review.
Who is Diagramwise for?
It is built for engineers preparing for system design interviews, developers learning distributed systems, and teams who want to document and review architecture decisions.
How does the architecture review work?
You build a diagram and write down your requirements, assumptions, and trade-offs. Diagramwise then reviews the design for scalability, reliability, data design, and trade-offs, and points out strengths, risks, and practical improvements.
Which cloud and diagram components are supported?
The canvas includes generic architecture components plus AWS, Azure, and GCP components, along with UML and entity-relationship diagram shapes.
Is Diagramwise free?
Diagramwise is free with usage limits. You can open the design studio, browse practice problems and learning paths, and build diagrams without paying. Features that cost money to run, such as AI feedback, have usage limits. Paid plans may be added later, and any change will be announced first.
