HTML Previewer
Paste HTML and see it rendered live, so you can check how markup will look.
Seeing your markup rendered
Writing or editing HTML, you often want to see the result immediately without saving a file and opening it in a browser. This renders your HTML live as a page, so you can check that a snippet displays the way you intend, test a layout, or preview an email template's markup in seconds.
Paste the HTML and the rendered output appears.
A quick sandbox for snippets
It is handy for the small, fast checks that make up a lot of front-end work: does this markup structure render right, how does this component look, what does this pasted HTML actually produce. For a quick preview of a self-contained snippet it beats spinning up a full environment. Bear in mind a preview like this shows the markup and styles you include; anything that depends on external files or scripts behaves as those are or are not available.
