How it works

From idea to diagram in under a minute

01

Drop nodes on the canvas

Classes, interfaces, flowchart shapes — pick from the sidebar and place them anywhere on the infinite canvas.

02

Connect and annotate

Draw relationships with a click. Label edges, set visibility modifiers, add stereotypes. Every UML connector type supported.

03

Share with one link

Hit Share. Anyone with the link sees your latest diagram instantly — no account, no plugin, no export.

01 / Diagram Power

Every relationship, precisely modeled

Full UML class diagram support — interfaces, abstract classes, and every connector that links them. From simple associations to complex compositions, model any software architecture with the precision your team expects.

  • Class diagrams with fields, methods, and visibility modifiers
  • All UML relationship types: inherits, implements, composes, aggregates
  • Interface and abstract class stereotypes
  • Flowcharts and system maps in the same canvas

What developers say

Built for people who ship things

"

Finally a UML tool that doesn't require three plugins and a Java runtime. Opened the tab, drew my service diagram, shared the link in Slack. Done.

I sent an architecture diagram to a client 30 seconds after finishing it. They opened it on their phone. No friction at all — that's rare.

draw.io keeps exporting broken SVGs and Lucidchart costs a fortune. Tuzilma just works. The snap-to-grid alone saved me so much time.

03 / Smart Canvas

The canvas that snaps into order

Magnetic alignment guides, smart snapping, and an infinite canvas that moves with your thinking. Every element lands exactly where it should — so you stay focused on architecture, not pixel-pushing.

Magnetic snapping

Elements snap to each other's edges, centers, and spacing automatically.

Smart alignment guides

Guides appear in real-time as you drag, showing you when things align.

Infinite canvas

Pan and zoom freely. Your diagram grows as your thinking does.
