Open-source Mac app
Design Canvas.
See your running app on one canvas.
I built Design Canvas to see the pages of a web app side by side while I work on the code. It’s a native Mac app with an infinite canvas, live previews and an MCP bridge for coding agents. It’s free and open source.
For macOS 14 and later. Source code under the MIT licence.
