Stop Creating a React Project Just to Preview a JSX File

If you're using AI coding assistants like ChatGPT, Claude, Cursor, or Lovable, you've probably accumulated dozens of JSX components. Generating them is incredibly fast. Previewing them? Not so much.

The Typical Workflow

Every time I received a JSX component, I found myself repeating the same process:

• Create a React project (or open an existing one)
• Copy the JSX file
• Install dependencies
• Fix missing imports
• Run the development server
• Wait for everything to compile

All of that... just to see one component. It felt like unnecessary overhead.

There Had to Be a Better Way

I asked myself a simple question: Why can't I just double-click a JSX file and preview it? We can instantly open images, PDFs, videos, and text files. Why should JSX files require an entire development environment?

That's what inspired me to build PreviewKit.

What is PreviewKit?

PreviewKit is a lightweight Windows application that lets you preview frontend components instantly. Supported file types include:

• ✅ JSX
• ✅ Vue
• ✅ HTML

No project setup. No dependency installation. No terminal commands. Just open the file and see the result.

Why I Built It

AI has dramatically changed frontend development. We're no longer spending most of our time writing components-we're reviewing, comparing, and refining them. That means fast visual feedback is more important than ever.

I wanted a tool that removed the repetitive setup process so I could focus on building better interfaces instead of preparing a preview environment.

Who Is It For?

PreviewKit is useful if you:

• Build React applications
• Work with Vue components
• Test standalone HTML files
• Generate UI with AI tools
• Review components from teammates
• Prototype interfaces quickly

If opening frontend files feels slower than it should, PreviewKit was built for you.

The Goal Isn't to Replace Your Framework

You'll still use React. You'll still use Vue. You'll still use Vite or Next.js. PreviewKit isn't trying to replace your existing workflow. It simply removes one frustrating step: Previewing components.

Final Thoughts

Developer productivity isn't only about writing code faster. It's also about removing repetitive tasks that interrupt your flow.

PreviewKit does one thing: Open frontend files and preview them instantly. No setup. No waiting. Just open, preview, and continue building.

I'd love to hear your thoughts. What part of your frontend workflow feels unnecessarily repetitive?
