Pencil is a free, open-source GUI prototyping and wireframing tool that runs as a Firefox extension or standalone app on Linux, macOS, and Windows. This fork is deprecated in favor of Pencil v3 by Evolus.
Use cases
- create wireframes for a website
- prototype a mobile app UI
- draw GUI mockups with stencils
- design UI mockups for free
- sketch interface layouts before coding
When to choose
- you need a free offline wireframing tool
- you want stencil collections like Bootstrap or Material Design
When to avoid
- you need an actively maintained tool
- you rely on newer Firefox versions
- you need Pencil v3 file format compatibility
