HTML live preview Beta
Click the globe on any HTML file to open it in a detected browser (Safari, Chrome, Firefox, Edge…), served over a loopback web server with live-as-you-type reload. Sibling CSS, JS, and images included.
A floating browser-globe button on any .html/.htm/.xhtml file opens it in a detected browser, Safari, Chrome, Firefox, Edge, or the system default.
The file is served over a tiny embedded web server bound to loopback only, so its sibling CSS, JS, and images load, and a small injected script reloads the page live as you type (it serves the buffer’s in-memory text, so you don’t have to save). No external tool, it uses the JDK’s built-in HTTP server.
Off by default. Enable it under Settings → HTML Preview. Read the deep-dive.
