Pencil Reviews — Discover what people think of this product.

Pencil brings visual interface creation directly into your coding workflow, so you can design UI on a canvas and instantly land it in production-ready code. Instead of bouncing between external mockup environments and your editor, Pencil lets engineers iterate visually while staying inside their preferred IDE.

By merging layout composition and implementation, Pencil reduces handoff friction and shortens feedback loops. Developers can experiment with component structure, spacing, and hierarchy on a canvas, then immediately see the corresponding code update in their project. This tight loop helps teams ship polished interfaces faster while preserving code quality and consistency.

Use Pencil to:

• Sketch complex layouts inside your editor while maintaining alignment with your existing codebase
• Eliminate design-to-dev translation overhead by generating code that matches your canvas precisely
• Speed up UI refactors by visually adjusting components and instantly applying changes in code
• Keep engineers in flow with a design experience built directly into their everyday development environment
