draw-a-ui is an open-source app that uses tldraw and a vision model to generate HTML from a drawn wireframe. Its repository links to Terragon Labs as its spiritual successor.
How SketchMason approaches the job
Draw labelled regions on a canvas, or drop in a photo of a sketch on paper, add a mood board and generate a UI design beside the sketch. Refine the result and develop related screens with the same visual direction. Export the design as HTML or a written brief.
Compare what happens after the first result
Both tools start from a drawing, so the first generation is the least telling part of a comparison. In SketchMason the design stays on the canvas beside its sketch. It can be revised in plain words with Design Chat or one element at a time in the editor, restructured into a version for a 390px phone, or extended into a flow of related screens that share its style guide. It leaves as a standalone HTML file per screen or a written brief in Markdown. Run the same small screen through draw-a-ui and look at the same three things: how a change is requested, how a second screen is made, and what file is handed to the next person.
Which workflow fits your next step?
Choose draw-a-ui when you want to explore or adapt an open-source drawing-to-HTML implementation. Choose SketchMason when you want to work in a hosted design canvas, use a mood board and develop related screens.

- What should I compare before choosing?
- Try the same small screen in both tools. Compare how you supply the layout, revise the result and hand it to the next person. Check current product documentation for plan limits.
- Can I try SketchMason in the browser?
- Yes. Make a free account and you are on the canvas: it comes with two generations and asks for no card.
