SnIPPETsX › Online HTML compiler. HTML, CSS & JS, live

Online HTML compiler. HTML, CSS & JS, live.

Free online HTML compiler and code runner. Write HTML, CSS and JavaScript, see the page render live, and share a link to your preview. No signup needed.

Write markup, style it, script it — and watch the page render. Then share the preview link.

The short answer

SnIPPETsX works as a free online HTML compiler. Create an HTML file, optionally add CSS and JavaScript tabs, and open the preview: SnIPPETsX combines them into one page and renders it in your browser. The project is shareable by URL, so others can see the live page and edit the code with you.

  • HTML, CSS and JS tabs are merged automatically into one preview page.
  • Linked files like style.css and script.js are resolved from your tabs.
  • Uploaded images can be referenced by file name in your markup.

An HTML playground built for sharing

HTML does not really compile — the browser renders it — but an online HTML compiler is the quickest way to test a layout, a CSS trick or a small interactive widget without creating files on disk. In SnIPPETsX you write HTML in the editor, add a style.css and a script.js tab if you need them, and open the preview to see the rendered page.

Multi-file projects behave like a real site. A <link> to style.css or a <script src="script.js"> is resolved against your own tabs, so you can structure code the way you would in a project rather than cramming everything into one file. Images you upload can be referenced by name.

Sharing is built in. Send the project URL to a student, a client or a teammate and they see the same code and preview; with live cursors you can tweak CSS together and both watch the page update. It is a practical alternative to screen-sharing a local dev server.
