How do I export an HTML artifact from Claude?

Click the download icon in the artifact panel — Claude saves the artifact as an HTML file to your computer. From there, you can open it in any browser, edit it, or upload it to a hosting service to share.

Where can I host a Claude artifact for free?

ShareDuo hosts Claude artifacts for free with no signup required. Other free options include Netlify Drop, GitHub Pages, and tiiny.host (free tier). ShareDuo is the fastest because it's purpose-built for Claude artifacts.

Will my Claude artifact still work after I export it?

Yes — Claude artifacts are self-contained HTML files with all dependencies included. They'll work exactly the same when opened from your computer or hosted on any web server, with one exception: AI-powered artifacts that call Claude's API will still need authentication to function.

How to Export and Share a Claude HTML Artifact

Claude can build impressive HTML artifacts — interactive charts, calculators, games, dashboards — but getting them out of Claude and sharing them publicly takes a couple of steps. Here's exactly how to do it. For a full comparison of all sharing methods, see 5 ways to share a Claude artifact. For broader context, see the complete Claude artifacts guide.

Step 1: Export the HTML from Claude

There are three ways to get the HTML out of Claude:

Download button (easiest)

In the artifact panel on the right side of the Claude interface, look for the download icon (an arrow pointing down). Click it and Claude saves the artifact as an .html file to your downloads folder.

Ask Claude to output the HTML

Type: "Show me the complete HTML for this artifact." Claude will paste the full code into the chat. Select all, copy.

Right-click → View source (in full-screen preview)

If you open the artifact in full-screen mode, you can right-click and choose "View Page Source" to see the raw HTML. Select all and copy.

Step 2: Host it publicly

Once you have the HTML, you need somewhere to host it that gives you a public URL. ShareDuo is built exactly for this.

Go to shareduo.com
Drop the .html file onto the drop zone, or paste the HTML into the text area
Choose how long the link should stay live
Click "Upload & share"

You'll get two links: a preview URL to share with anyone, and a private manage URL to track views and delete the artifact later. This is the cleanest way to share without requiring a Claude account. Looking at other hosts? Compare hosting options.

Why not just use Claude's Publish button?

Claude's Publish creates a public link — standard HTML artifacts load for anyone, no account required. The limitations are different: no expiry control, no password protection, no view analytics, and published artifacts may be indexed by search engines. AI-powered artifacts (ones calling Claude's API at runtime) do require sign-in.

ShareDuo adds what Publish is missing: expiry windows, password protection, view analytics, and noindex by default. If you need any of those controls, ShareDuo is the better path.

What kinds of Claude artifacts work?

Any HTML artifact Claude creates will work — including ones that use:

Chart.js, D3.js, or other charting libraries loaded from CDN
Google Fonts
Tailwind CSS via CDN
Interactive JavaScript (games, calculators, forms)
Inline CSS animations

ShareDuo's preview server is specifically configured to allow these — unlike some hosting services that block external scripts.
