What is MockPilot?

MockPilot is a free, open-source desktop application that transforms any live webpage into an editable, self-contained HTML mockup. Instead of rebuilding designs from scratch in tools like Figma, you capture a full page or a single component directly from a URL. The app automatically extracts typography, colors, components, and icons into a reusable asset library. You then edit everything using plain English — no design or coding skills required. The result is a clean, standalone HTML file you can export and share. MockPilot runs on macOS and Windows.

Who it's for

• Designers who need rapid, realistic mockups without leaving the browser or switching to complex design tools
• Product managers who want to propose visual changes or iterate on UI concepts using natural language instead of design software
• Developers who need to quickly prototype or modify web interfaces and export clean, production-ready HTML without manual coding

Key features

Capture from any URL

MockPilot lets you grab full-page screenshots or isolate single components from any live website. The captured content becomes the foundation of your mockup, preserving the original layout and styling.

Auto-extracted asset library

When you capture a page, the app automatically identifies and organizes its typography, color palette, components, and icons into a reusable asset library. This ensures every edit stays consistent with your brand or design system.

Natural language editing

You describe changes in plain English — "make the header darker" or "swap the hero image" — and MockPilot applies them using your extracted assets. No CSS, no drag-and-drop, no learning curve.

Export as standalone HTML

Once your mockup is ready, you export it as a clean, self-contained HTML file. The output is portable, lightweight, and ready to share or integrate into a project.

What stands out

MockPilot turns any webpage into a mockup you can edit with words, not wireframes.

Most mockup tools require you to start from a blank canvas or a template library. MockPilot flips that model: you start with a real, live webpage and modify it conversationally. The automatic extraction of design tokens means you're never guessing fonts or colors — the AI already knows what belongs. This makes it uniquely fast for iterating on existing designs or creating realistic prototypes without touching a design tool.

Worth checking out if…

You're a designer, product manager, or developer who wants to create realistic web mockups in minutes without learning design software or writing code. MockPilot is especially useful if you frequently need to propose UI changes, prototype variations of existing pages, or export clean HTML for further development. Since it's free and open source, there's no barrier to trying it on your next project.
