The best ShareDuo alternative is Hostus when the link has to keep working: a free Hostus link never expires, while a free ShareDuo link lasts 1 hour, 1 day or 7 days, and permanent links are part of its Plus plan.
ShareDuo is good at what it was built for. You drop or paste a Claude artifact with no account and get a link in seconds that anyone can open without a Claude login, with an optional password, hidden from search engines by default. People go looking for an alternative when the link has to outlive a week (a proposal, a client report, a page linked from a newsletter), when the page has a form, or when they want to know who actually read it. Below, six options with facts read on each vendor's own site on 2 November 2026, and Claude's help center reread on 7 November 2026.
Which ShareDuo alternative should you pick?
Our answer is Hostus, best if the link has to keep working. Then, by what you need instead:
- Stacktree if you need your own domain and an email check on access, and the budget starts at $19 a month.
- Pagelive if you send AI-made proposals and decks and want a confirmed email and reply forms, at $15 a month after a trial.
- Tiiny.host if you want a general drag-and-drop host; check their site for current limits.
- Netlify Drop if the page may grow into a full site with a build.
- Claude itself if you are on a paid plan, the page is a plain artifact (not a doc, with no saved data or form the reader must see), and on Team, External sharing is on.
Why people look for a ShareDuo alternative
- The link expires. Free links last 1 hour, 1 day or 7 days, your choice. 30-day and permanent links are on Plus, $4.99 a month (shown struck through from $9.99), which comes with 10 active artifacts. A proposal sent on a Monday stops opening the next Monday.
- There is no account behind a free upload. ShareDuo's FAQ says nothing is stored about the uploader, and the manage link you keep after uploading is the only thing tying you to the artifact. That is private, and it means a lost manage link is a lost way to change or delete the page. (The ShareDuo connector for Claude does ask you to log in.)
- Analytics stop at views. The built-in analytics are a view count and the last time the page was opened; Plus adds your own Google Analytics tag.
- No word on forms. ShareDuo's site does not mention form submissions, so a page that asks the reader something needs another service to receive the answer.
How the alternatives compare one by one
1. Hostus
Best if the link has to keep working. Hostus hosts the HTML file Claude made, or any single HTML file or folder of HTML with media, at your-slug.hostus.page. The free plan has no clock and asks for no card: 20 documents, 2 MB in total, and links that stay up until you delete them. If you want one to stop, publish through the connector or the API with an expires_at date up to 90 days ahead.
What a week-long link cannot give you:
- The same link, updated. Replace the file, or ask Claude to update it through the connector. The History tab keeps the last 20 versions to compare and restore.
- A form that records answers. Any
<form method="post">with named fields stores responses, 100 a month free; past that they are kept until you subscribe. - An email gate. A page is Private (only people you invite, by magic link), Email-gated (the reader types an email first, optionally limited to a list or an
@domain) or Public. - Reading by section. Who opened it (the email, on a gated page), when, for how long, and which h2 and h3 sections they read. No cookies.
- Ask and Reply for the reader. With Ask on, the reader asks the page a question and gets an answer that cites the section: 20 questions a day per account on free, 200 on paid. With Reply, they leave a private note on a section and you are notified.
- A Claude connector. Add Hostus in Claude as a custom connector with OAuth; Claude publishes with
hostus_uploadand updates withhostus_update. You set who can open the page in the dashboard.
Paid is $9.99 a month or $49.99 a year: 200 MB, unlimited documents and unlimited responses.
2. Stacktree
The free tier is a trial of 3 pages with a badge; trial pages last 7 days, or 30 days after the last open, up to 90. Solo is $19 a month with one domain of your own and the badge removed; Studio is $79 with 10 domains and time, scroll and attention analytics; Firm is $249. Paid plans add a password, a single-use magic link, and an email-domain gate that confirms the address with a magic link. Readers can leave notes anchored to elements, and there is an MCP server. Forms are not documented. Pick it if you need your own domain and a gate that checks the address, and $19 a month fits.
3. Pagelive
Built for AI-made proposals, reports and decks sent as private links: a password or a confirmed email, analytics of who opened it, for how long and which sections they read, "reply forms", your own subdomain by CNAME, and an MCP server for Claude, Claude Code, Cursor and Codex. Free for 2 public pages; $15 a month or $150 a year after a 10-day trial. Pick it if you send proposals for a living and want the email confirmed before the page opens.
4. Tiiny.host
A general drag-and-drop host. Third-party reviews describe a narrow free plan with one project, a tiiny.site address and a Tiiny banner; their pricing page did not load for us today, so check their site for the numbers. Pick it if you want a general host rather than one built around Claude artifacts.
5. Netlify Drop
Drag a folder onto the page and it is live. Netlify's docs say "no account required"; without a login the files go up as they are, and a logged-in drop runs your build. To update, drag the new folder onto the Deploys page. The docs we read say nothing about how long an anonymous drop stays up. Pick it if the page may grow into a full site.
6. Claude itself
Claude's help article Share artifacts, read on 7 November 2026, says most artifacts shared with "Anyone with the link" open without a Claude account or sign-in, on Pro, Max and Ultra. Not on Free, which has no such link for new artifacts. Docs open only for people signed in, some dashboards show their content only after sign-in, and readers who aren't signed in can't see data the artifact saved. On Team and Enterprise the link works only when an Owner has turned on External sharing or allowed that artifact. A legacy artifact published from a chat before 16 September 2026 opens for anyone with the link without an account. Pick it if you are on a paid plan, the page is a plain artifact (not a doc, with no saved data or form the reader must see), and on Team, External sharing is on.
And ShareDuo, if you stay
Free with no account to upload, and it takes HTML, React, SVG and Mermaid; its FAQ says artifacts that call Claude's API at runtime will not work. Its connector for claude.ai and Claude Code has six tools, among them updating an artifact on the same URL and switching search indexing on or off. Stay if your links live a week or less, or a password matters more to you than knowing who read the page.

Read on each vendor's own site on 2 November 2026, Claude's row on 7 November 2026. "Check their site" means the fact was not on the pages we could read; Tiiny.host is left out because its pricing page did not load for us.
Moving a ShareDuo link to Hostus
- Get the HTML. It is the file you gave ShareDuo. If you only have the link, ask Claude for the artifact again as one self-contained HTML file.
- Publish it. Drop it on hostus.io, type your email and click the magic link. Or ask Claude to publish it through the Hostus connector.
- Pick who can open it. Every page starts Private. Choose Public, or Email-gated if you want to know who opened it.
- Test the form, if there is one. A submission you make while logged in as the owner is marked as a test and does not count.
- Send the new link. The ShareDuo one expires on its own, or delete it from its manage page.

Good to know before you switch
ShareDuo Plus puts a page on your own domain (its example is prototype.yourdomain.com); Hostus cannot, and the link is always your-slug.hostus.page. The file stays yours, so if the page later needs your domain, it moves to any host as is. Every Hostus page carries a small "Published with Hostus" pill in the bottom-right corner, free and paid, and a form shows a short "Form by Hostus" line under its success message.
On search engines it is close to a draw: ShareDuo hides pages from search by default, and Hostus marks public pages noindex. The difference is that ShareDuo lets you switch indexing on and adds Search Console verification on Plus, while a Hostus page never shows up in Google. Hostus has no password: the email gate does not check the address, so the link is the credential. Uploading asks for an email and a magic link, where ShareDuo asks for nothing. And the free plan is 20 documents, 2 MB in total and 100 form responses a month.
