How it works

Three steps to a shareable link

From Claude, VS Code, anywhere — drag a file or paste the code directly.

Choose an expiry window and optionally add a password. Defaults are fine too.

3

Share your link

Anyone can open it in any browser — no account, no Claude subscription required.

FAQ

Common questions

Security & Privacy

Is my file stored permanently?
No. Every artifact expires automatically based on the window you choose — 1 hour to 30 days. After expiry the file is deleted from storage. You can also delete it early at any time from your manage page.
Who can see my file?
Only people with the link. Nothing is indexed, listed, or shared publicly. Add a password to restrict access further — only people with both the link and the password can view it.
Do you need my email or account?
No. Nothing is stored about you as the uploader — no email, no name, no account. The only thing linking you to your artifact is the manage link you keep after uploading.

Using ShareDuo

What file types does ShareDuo support?
HTML files only (.html). If you have a Claude artifact, download it from Claude or ask Claude to output the full HTML code. Max file size is 5 MB.
What's the difference between the preview link and the manage link?
The preview link is what you share — anyone with it can view your artifact. The manage link is private and only for you — it shows view counts and lets you delete the artifact.
Is ShareDuo free?
Yes, completely free. No paid plans, no credit card, no account required.
