Show new developers, your clients and the whole team how your system works.

Flozu is a live map of your architecture. Draw how your systems connect, watch traffic move through them, and walk anyone through it, step by step.

Make a map people want to look at

Live cards, moving lines and colours that work in light and dark.

See every part

Join anything to anything

Drag from one part to the next, and traffic starts moving along the line.

Live drawings

Every part shows a small moving picture of what it does, and any part can wear any drawing.

Lay out each card your way

Pick how each part's card reads, and mix them freely on one map.

Any colour you like

Colour parts, lines and zones from a palette drawn for both themes, or pick your own.

Or let your assistant draw it

Ask the assistant you already use. It reads your code and hands you the map as a proposal to review.

Drawn for dark and light

Every colour has a shade for each theme, so a map reads well in both.

One map, start to finish

A shop's checkout on Black Friday, from the first part to the story you tell about it.

With your assistant

Your code stays on your computer. The assistant sends Flozu only the map it draws.

Good questions

More answers
Do I need an account?

No. On the web you can continue as a guest, and your maps stay in your browser. An account keeps your maps online, so they open on any computer, and lets you share them with a team.

Is Flozu free?

Yes, during the beta. It isn't sold yet.

Does Flozu connect to my systems?

No. Flozu never calls, deploys, monitors or runs anything. The motion and the scenarios come from the numbers you put on the map.

Can my assistant work with my maps?

Yes. Connect Claude, Cursor, Codex or another assistant to your account, and it can map your code, read your maps and suggest changes, each one a proposal for you to adopt.

Is my map sent anywhere when I share a link?

No. A share link carries the map inside it, after the #, and browsers never send that part of an address to a server.

Can Flozu show what happens when something breaks?

Yes. A failure drill takes a part, a line or a whole zone down in a scenario, and shows what fails, what takes over and what to change.

Start with one map

Pick a template or a blank canvas, and join your first parts.
