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.

AI via MCP

Connect Claude Desktop or Cursor and say "Create a microservices diagram" — it appears instantly.
