Why Use an Online HTML Previewer?

No local setup

Don't want to set up a local server or open a text editor? Preview HTML directly in your browser.

Instant feedback

See changes the moment you paste them. No save-refresh cycle, no file management.

Share what you see

Most HTML previewers show you the result but can't share it. OneClickLive does both — preview and deploy.

Works with frameworks

Not just plain HTML — auto-detects React (JSX) and Vue, wrapping them with the right runtime.

FAQ — Preview HTML Online

Can I preview HTML online without downloading anything?

Yes. OneClickLive runs entirely in your browser. Paste your HTML code and see the preview instantly — no software to install.

Does the preview work with CSS and JavaScript?

Yes. The preview renders full HTML including inline CSS, JavaScript, and external CDN libraries like Tailwind CSS or Chart.js.

Can I share my HTML preview as a link?

Yes. Click Deploy to turn your preview into a permanent live URL anyone can visit. Free tier includes 3 projects with 7-day hosting.

What code types can I preview?

Plain HTML, CSS, JavaScript, React (JSX), and Vue. The platform auto-detects the code type and wraps it appropriately.

Is it free to preview HTML online?

Yes, completely free. The preview works without an account. Creating a shareable URL requires a free account.

How is this different from CodePen?

CodePen is a code playground that always shows the editor alongside the preview. OneClickLive previews your code AND deploys it to a standalone URL — visitors see only your page, not an editor.
