Built for technical design
Live cursors, comments and shared sessions make architecture reviews easier.
Software architecture
Draw services. Connect dependencies. Explain the system.
Sketch services, APIs, queues and databases on an infinite canvas, with real-time collaboration, comments, version history and export to PNG, JPG, PDF or Mermaid.
Real-time · Comments and history · Export to PNG, JPG, PDF
Fast to iterate
Start from Mermaid, Miro or a blank board and keep the hand-drawn clarity.
Easy to share
Present the system live, then export a copy for specs, RFCs, tickets or docs.
Why it fits
Built for architecture work, not a generic whiteboard
You need a space where system boundaries, dependencies and technical decisions stay understandable while the team is still iterating.
Map systems and dependencies
on one canvas
Model frontends, backends, queues, databases and service boundaries without fighting rigid layout rules.
Review in real time
in context
Share a live session, follow cursors, leave comments and present the architecture as the team reviews it.
Reuse existing work
no redrawing
Import Mermaid or Miro, then export what the team agreed on in the format they need next.
Keep decisions traceable
not just the picture
Comments and version history capture why the architecture changed, not only what the final view looks like.
What you can map
Microservice architectures and service boundaries.
Web stacks with gateways, workers and data stores.
Cloud and infrastructure views for AWS, GCP, Kubernetes or Docker.
C4-style conversations for early architecture reviews.
Ownership, dependencies and team coordination flows.
Frequently asked questions
Is this only for brainstorming?
No. Diagraw is a good fit for early architecture design, technical reviews, infrastructure maps and product-engineering alignment work.
Can I share the diagram with the team?
Yes. Open a live session with cursors, presence and comments, or send an editable copy so someone else can review the work without touching your original board.
Can I reuse Mermaid?
Yes. Import Mermaid code, use it as a visual starting point and export Mermaid again when you need it.
Can I import from Miro?
Yes, by connecting your Miro account from the Integrations menu (signing in is required). We bring in the supported shapes, text, connectors and images.
Which export formats are available?
Export to PNG, JPG or PDF, save a Diagraw file to reopen later, or generate Mermaid and Docker Compose code from your diagram.
Is it free, and do I need an account?
Drawing and sharing by link are free with no account for guests. A free account adds your library, version history and Miro import.
