What is the Wireframe Builder?
The Wireframe Builder is a free, browser-based drag and drop wireframe tool that lets you prototype web page layouts without writing a single line of code. Place UI blocks — headers, navigation bars, hero sections, sidebars, cards, forms, tables, footers, and more — onto a resizable canvas and arrange them visually to plan your design.
Once your layout is ready, export it as a PNG image for presentations, a semantic HTML skeleton to hand off to developers, or a Markdown table for documentation. Everything runs in the browser — no signup, no data sent to any server.
Key Features
- Drag and drop layout blocks: header, nav, hero, sidebar, main content, card, button, image placeholder, footer, form, table, and divider

- Undo and redo support for non-destructive editing
- Export as PNG image, HTML file, or Markdown layout table
- Color-coded blocks (gray, white, blue, green) for visual grouping
