AI coding assistants have changed the way I build frontend applications.
Instead of spending 30 minutes creating a UI component, I can describe what I want and get a React or Vue component in seconds.
That's amazing.
But I noticed something interesting.
The faster AI became at generating code, the more obvious one old problem became:
Previewing that code was still slow.
The Productivity Gap
Imagine this workflow.
You ask an AI to create a pricing card.
It generates a JSX file.
Now you want to know one thing:
Does it actually look good?
Instead of seeing the answer immediately, you have to:
- Create a React project
- Install dependencies
- Copy the component
- Run the development server
- Wait for everything to load
Ironically, previewing the component often takes longer than generating it.
That doesn't make sense anymore.
The Idea Behind PreviewKit
I wanted something much simpler.
I wanted frontend files to behave like normal files.
Double-click.
Open.
Preview.
Done.
That's exactly what PreviewKit is designed to do.
More Than Just JSX
Although PreviewKit started as an idea for React developers, I quickly realized the same problem exists across different frontend technologies.
That's why PreviewKit supports:
- JSX
- Vue
- HTML
Whether you're testing an AI-generated component, reviewing a teammate's work, or opening an old UI prototype, the experience should be identical.
No setup.
No configuration.
No unnecessary steps.
Why This Matters
The future of development isn't just about writing code.
It's about reviewing, testing, and iterating faster.
AI has accelerated code generation.
Developer tools now need to accelerate everything that comes after it.
PreviewKit helps close that gap by making visual feedback almost instant.
Built for Everyday Development
I didn't build PreviewKit for massive enterprise projects.
I built it for everyday moments.
Opening a component.
Checking a layout.
Reviewing a UI.
Testing an idea.
Those are tasks we perform constantly.
Removing friction from those moments makes development feel noticeably smoother.
Final Thoughts
Some tools try to solve everything.
PreviewKit focuses on solving one problem really well.
Opening frontend files shouldn't require creating an entire project.
It should be as simple as opening an image.
That's the experience I'm trying to build.
If you're constantly working with JSX, Vue, or HTML files, I'd love to know:
How do you currently preview standalone components?
