Think at the right level
Map responsibilities and data flow with service, queue, cache, database, web, and mobile building blocks.
Software architecture canvas
Explain the system before the meeting ends.
Turn a design conversation into an editable system map while the decisions are still fresh. Canvazor keeps services, data stores, clients, and connections easy to place without forcing a polished diagram too early.
No account needed · Local-first boards · PNG and SVG export
Built for design conversations
From architecture idea to shared explanation.
Use the canvas for the uncertain first sketch and keep the same editable board as the design becomes concrete.
Keep working diagrams editable
Autosave locally, export PNG or SVG for documentation, and retain the native board when the architecture changes.
Share a current view
Move selected boards to the cloud and issue a revocable read-only link that reflects the latest saved revision.
Searchable components
The building blocks software diagrams actually need
Start with familiar architecture components, then mix in databases, messaging, containers, and official cloud-provider icons from the same searchable toolbox.

How it works
A useful diagram in three passes.
Start with the architecture decisions, then add only the detail your audience needs.
Name the boundaries
Place the clients, services, and stores that define the system you are discussing.
Draw the important flow
Connect requests, events, and dependencies without spending the meeting aligning perfect boxes.
Save the explanation
Keep the editable board locally or save it to the cloud when the diagram needs to travel.
Questions, answered
Before you open the canvas.
Can I start a software architecture diagram without signing up?
Yes. The canvas opens without an account and saves local boards in your browser. Sign-in is only needed for cloud boards and share links.
Which software architecture components are included?
The toolbox includes services, databases, caches, queues, file stores, web applications, and mobile applications, plus common infrastructure and cloud-provider libraries.
Can I export a diagram for technical documentation?
Yes. Canvazor supports PNG and SVG exports, along with native .cvz files and compatible Excalidraw import and export.
