Logic that reads visually

Triggers, conditions, delays, and actions stay legible from the first draft to the final export.

Code you can actually use

Generate complete Home Assistant automations and positioned Node-RED flows from the same canvas.

Private by architecture

Flows, credentials, and device connections stay in your browser. There is no account or cloud database.

From idea to automation

A shorter path
to a smarter home.

Compose

Add devices and logic blocks, connect valid paths, and tune every value in the inspector.

Verify

Catch incomplete paths before export and watch each step execute in the built-in simulator.

Ship

Download portable JSON, copy a share link, export target code, or push through the M-UI Bridge.

Make the next automation the easy one.

Start blank or clone a template. Your work saves automatically in this browser.
