The Software Architecture Diagram Tool That Lives Where Your Team Actually Works.
Your system architecture should not live in a separate tool that nobody opens after the meeting ends. Zunoy Canvas brings Mermaid diagrams, UML components and real-time engineering collaboration onto one board — so your architecture is always where your team is, always up to date and always useful.

THE ARCHITECTURE PROBLEM
Your Architecture Diagram Is Always Out of Date. Here Is Why.
Every engineering team has one — the architecture diagram that was accurate on the day it was made and has been quietly wrong ever since. The system changed. The diagram did not.
PICTURE THIS
Five Engineering Moments Where Zunoy Canvas Changes Everything.
The System Design Session
Your team is designing a new microservice. Someone types a plain English description of the service flow into Zunoy Canvas. AI generates a clean Mermaid diagram instantly. The team edits it live, argues about the architecture in the comments, and resolves it with a vote. By the end of the session the diagram is done, the decision is documented, and the board is the single source of truth.
The Architecture Review
Quarterly architecture review. The board is already built — every service, every dependency, every integration mapped and connected. The lead walks the team through it using the laser pointer. Engineers add comments where they spot gaps. Nobody has to ask "wait, what does this connect to?" because the answer is already on the board.
The Onboarding Doc That Actually Gets Used
New engineer joins the team. Instead of a PDF that was last updated eight months ago, they get a link to the architecture board. Every service is there, every connection labelled, every decision has a comment explaining why it was made. They explore it at their own pace and come to their first architecture review already oriented.
The Post-Incident Diagram
Production incident. The team needs to map what happened — which service failed, what it affected, how the failure propagated. The team builds the incident map in real time, drawing connections and adding sticky notes for each failure point. By the time the incident is resolved, the post-mortem diagram is already done.
The API Flow Nobody Could Agree On
Three engineers, two interpretations of how the API should work. Someone draws both versions side by side using Mermaid diagrams. The team votes. The winning version gets refined; the losing version stays for reference. The decision is documented, dated, and connected to the meeting notes. No more arguing about what was decided.
YOUR ENGINEERING TOOLKIT
Every Tool Your Team Needs for Architecture Work. Built Into the Board.
No plugins. No exports. No switching tools. Everything below lives on your Zunoy Canvas board from the moment you open it.
EVERY FEATURE, IN DETAIL
The Full Engineering Toolkit
Fifteen tools, grouped by what you're doing — diagramming, documenting, collaborating, and managing your architecture over time.

Frames
Divide your architecture board into named sections — Frontend, Backend, Infrastructure, APIs, Third Party Services. Navigate between layers cleanly without losing context.
Tables
Add structured tables for API documentation, service inventories, dependency matrices and environment comparisons — directly on the board alongside the diagrams they reference.
Code Blocks
Add code snippets directly onto the canvas — API contracts, configuration examples, pseudocode. Your diagram and your code in the same place.
Image Library
Drop in screenshots, infrastructure diagrams, error logs and system exports. Everything saves automatically and is available across every board in your workspace.

Real-Time Collaboration
Every engineer sees every change the moment it happens. No version confusion. No "who has the latest copy?" Just one board, one truth, one team building together in real time.
Comments & Mentions
Leave feedback directly on any element of the diagram — a service node, a connection, a decision. Mention a teammate and they get notified instantly.
Live Voice Room
Talk through the architecture while you build it — without leaving the board. No Zoom. No Meet. No context switching. Just your team and the diagram.
Activity Timeline
Every change to the board tracked and timestamped. Know exactly who updated what and when — so your architecture history is as documented as your architecture itself.

Version Control & Restoring
Architecture changes over time. Version control means every previous state of your board is saved and restorable — so you can see how your system looked six months ago and understand why decisions were made.
Private Templates
Build your team's standard architecture board structure once — service map, API layer, data flow, deployment diagram. Save it as a private template. Every new system starts from a structure your team already trusts.
Project Owner Transfer
Team member leaving? Transfer the architecture board to the new owner in one click. All history, all context, all diagrams — intact.

FAQ
Frequently Asked Questions
Can I build software architecture diagrams on Zunoy Canvas?
Yes. Zunoy Canvas is built for technical diagramming — with native Mermaid diagram support, UML components, flowcharts, sequence diagrams and AI-powered diagram generation from plain English descriptions. Everything renders directly on the board and is fully editable by your whole team in real time.
What UML diagram types does Zunoy Canvas support?
Zunoy Canvas supports the full range of UML diagram types — class diagrams, sequence diagrams, use case diagrams, activity diagrams and component diagrams — using drag and drop UML components built directly into the canvas.
Can I document architecture and diagrams in the same place?
Yes. Zunoy Canvas lets you add tables, code blocks, sticky notes, images and comments alongside your diagrams on the same board. Your architecture diagram and the documentation that explains it live together — so context never gets separated from the diagram it belongs to.
Is Zunoy Canvas free for engineering teams?
Yes. The free plan includes Mermaid diagrams, UML components, real-time collaboration, comments and 10 AI credits per month — enough for small teams to start mapping architecture without any cost. Upgrade to Pro or Team when your team grows or needs more advanced features like version control and voice rooms.
Does Zunoy Canvas support Mermaid diagrams?
Yes. Mermaid is built natively into Zunoy Canvas and available on all plans including Free. Write Mermaid syntax directly on the board and watch it render as a clean professional diagram instantly. No plugin, no extension, no external tool needed.
How do engineering teams collaborate on architecture diagrams in real time?
Every change on a Zunoy Canvas board is visible to every team member the moment it happens. Engineers can draw, comment, vote and discuss architecture directly on the diagram — with live cursors showing exactly where each person is working. The live voice room means teams can talk through architecture decisions without leaving the board.
How does Zunoy Canvas compare to Lucidchart for architecture diagrams?
Lucidchart is a well-established, dedicated diagramming tool. Zunoy Canvas takes a different approach — combining diagramming with a full collaborative whiteboard, including voting, activity timelines, comments, and AI diagram generation, on one board.
Can I use AI to generate architecture diagrams on Zunoy Canvas?
Yes. The Text to Mermaid AI feature lets you describe your system in plain English and generates a clean Mermaid diagram on the board instantly. The Board Assistant can also read your existing architecture board, identify gaps, suggest missing components and answer questions about what is already documented.
