What is HTMLOL?

A browser-based HTML editor with a live preview, email-client checks, and share-a-link publishing — no install, no build step.

HTMLOL is an HTML editor that runs entirely in your browser. You write (or paste, or open) HTML, and a live preview renders it instantly beside your code. There's nothing to install and no build step — open the page and you're working.

It's built for two kinds of people at once: someone who can read a <div> but would rather be shipping than fighting a bloated IDE, and the developer who wants a fast scratchpad with a real preview and a one-click way to share the result.

What you can do

• Write and preview HTML with no setup — see Editor views.
• Edit visually — click an element, drag it into place, resize it, edit its text. See Visual editing.
• Catch email bugs before you send, with built-in compatibility checks (Email checks).
• Publish a link in one click — open, password-protected, or expiring (Share a link).
• Stay on brand with curated colors and fonts, or your own brand book (Brand & Favorites).
• Export finished work as HTML or PDF.

How it works

Everything runs locally in your browser. Your markup isn't sent anywhere until you choose to publish a share link or upload an image. You sign in with a password or a six-digit email code — which lets HTMLOL count your files and unlock paid features. That's the whole model: local-first editing, with an account only where it needs one.
