Publish a site
Three steps

How to publish a site online

From a ready folder or ZIP to a public link in seconds. No builds, no servers, no setup.

01

Upload a file

Drop a folder, a ZIP or an HTML file. Up to 20 MB per site, with index.html at the root.

02

Get a link

Every site gets its own unique URL like mypage.htmlkin.io

03

Share it

An anonymous link works for 24 hours. Sign up and your site stays for good

Use cases

What people use htmlkin for

A static site where full-blown hosting is overkill.

Presentations and landing pages

Share a presentation or a one-page landing page by link — no deploys, no hosting.

Reports from AI

Made an HTML report or dashboard in ChatGPT or Claude? Publish it and share the link in a second.

Demos and prototypes

Show a working interface prototype to a client or your team, fast.

For offline businesses

Invitations, menus, checklists, instructions — things that don't deserve a full website.

Examples

What people have published on htmlkin

Live sites whose authors opened them to search engines. Each one opens by link — see how it looks on a custom domain and on a subdomain.

Custom domain

Use your own domain

Publish your site on your own domain — .com, .io or any other. One DNS record is all it takes.

Any domain or subdomain

Set up a root domain or as many subdomains as you need.

Automatic SSL

The certificate is issued and renewed on its own — nothing to configure. HTTPS by default.

Lead forms

Collect leads from your page

Forms for leads, requests, feedback, webinar sign-ups and more. A visitor clicks “Send” — and the submission shows up in your dashboard.

Your own markup

A form is a regular <form> with our address in action. The fields, layout and styles are yours: htmlkin doesn't inject anything into the page.

Submissions in your dashboard

They arrive in the Forms section: search by field, mark as read, export to CSV. Kept until you delete them.

No page reload

The snippet's script sends the submission without taking the visitor away from the page.

For sensitive content

Lock your site
with a PIN

Set a PIN and visitors see an entry screen instead of the content. Change or remove the code at any time.

A PIN is light protection against casual visitors. Server-side rate limits and temporary lockouts stop brute force.

FAQ

Frequently asked questions

How do I host an HTML file for free?

Drop the file into the form at the top of this page or paste the HTML code — a public link appears in a few seconds, no sign-up needed. Without an account the link works for 24 hours. To keep the site, sign up: the free plan gives you 1 site up to 20 MB, a custom domain and a promo banner at the bottom of the page.

What can I upload?

An HTML file, a site folder or a ZIP archive. The site's entry page is index.html at the root. A site holds up to 500 files, and the total size is limited by the plan's storage: 20 MB on the free plan.

How long does a link live?

Without an account, 24 hours. After a free sign-up the site lives as long as people visit it: after 30 days without visits it moves to the archive, and you can restore it from your dashboard for another 30 days. On paid plans the site stays with no time limit.

Can I use my own domain?

Yes, on any plan, including the free one. One DNS record is all it takes, and the SSL certificate is issued and renewed automatically. You can connect a domain to every site on your plan. Without one, the site opens on a subdomain like mypage.htmlkin.io.

Can AI publish for me?

Yes. On any plan, including Free, Claude, Claude Code, Cursor and other MCP clients publish the site through the MCP server htmlkin.io/mcp or the REST API and return the link right away. Even without an account, the browser extension adds a publish button to HTML code in chats with ChatGPT, Alice by Yandex and GigaChat.

How much does it cost?

Publishing without an account and the free plan cost nothing. Paid plans start at $8.33/mo billed yearly: no promo banner, more sites and storage, PIN protection, the REST API and the MCP server.
