MockPilot

MockPilot is an open-source desktop app that captures any live webpage and turns it into a self-contained, editable HTML mockup. According to its README, it targets designers, product managers, and developers who want quick, realistic mockups without opening a tool like Figma. It runs on macOS and Windows and lets you revise the captured page by describing changes in plain language.

What It Is

MockPilot pairs webpage capture with natural-language editing. You point it at a live page, it saves that page as a portable HTML file, and you then edit the result by typing instructions instead of hand-coding markup. Because the output is one self-contained file, the mockup stays easy to share and keeps working after capture.

How the Workflow Works

The README describes a simple loop. First you capture a live web page, which MockPilot converts into a self-contained HTML file using a headless browser. Then you edit, describing the changes you want in natural language so the app rewrites the markup for you. Finally you iterate, refining the same mockup without re-capturing the source page. This suits quick UI experiments on top of existing sites and realistic mockups for stakeholder review.

Tech Stack and Architecture

MockPilot is an Electron application scaffolded with Electron Forge and bundled with Vite. The README lists a UI built from React, TypeScript, Tailwind CSS, and shadcn/ui, with page capture handled by a headless browser. Distribution is automated: pushing a version tag triggers a GitHub Actions pipeline that builds and publishes macOS and Windows artifacts. The README notes the app is not yet code-signed, so both platforms show security warnings on first launch that require manual steps to bypass.

Installation and Development

The README documents a download-and-override flow on each platform: on macOS you unzip the app and clear its quarantine attribute, while on Windows you proceed past the SmartScreen warning. For local development it lists Node.js 22 or newer plus npm, with the app launched through standard install and start commands.

Release Activity

The project ships frequently. Its public releases run in close succession through early and mid-2026, with v0.8.3 marked as the latest stable release on June 10, 2026, and a v0.8.4 published as a pre-release. The pattern points to active, early-stage development rather than a settled, mature product.
