Sketch UI mockups directly on live websites in Chrome
UI Builder is a Chrome extension for quick, sketch-style wireframes directly in your browser. Drag buttons, inputs, headers onto any page or blank canvas. Perfect for fast feedback, live demos, and client calls.
Hey Product Hunt! Write it from my heart - without AI :)
I’m an IT analyst, and the idea for UI Builder came during one of those classic Zoom calls with a client while discussing design changes in a CRM system.
I realized how tricky it can be to quickly show what a new button or checkbox might look like - right there, in the browser. Sometimes I used screen drawing tools (not bad, but clunky), or I’d just sketch something later and send it for review after the call.
But being able to test and agree on a rough idea live, during the conversation - really speeds things up.
So I built this: ➤ Drag and drop UI elements onto any webpage or blank canvas ➤ Edit text in place, resize blocks, rearrange things ➤ Take screenshots or copy to clipboard ➤ Works locally, no data tracking, no login
I searched around and couldn’t really find a Chrome extension that does this - most are just drawing tools or annotation overlays.
Have you seen a tool like this before? Would love your thoughts or similar examples you’ve used.
