Pencil is a free prototyping tool for sketching app and website interfaces before any real building starts. You place ready made windows, buttons, forms and other screen elements on a page and arrange them into a mockup that shows how a product could look and flow. It suits designers, developers and students who want quick wireframes without a heavy design suite.

Key Features

  • Built in shape collections for desktop, web and mobile interfaces
  • Android and iOS stencil sets included for phone and tablet mockups
  • Link pages together to show how screens connect in a flow
  • Export your work to formats such as PDF, SVG and text documents
  • New AI support through a built in Model Context Protocol server

FAQs

Is Pencil really free?

Yes. Pencil is a free open source project. You can install it and use it for mockups at work, at school or at home without paying for a licence.

What can I make with Pencil?

Wireframes and mockups of apps, websites and desktop software. It is for planning screens and flows, not for writing the final working product itself.

Can I share my mockups with other people?

Yes. Export options include PDF and SVG files plus document formats, so you can send a design to a client or a team mate in a form they can open easily.
