# htmlkin.io > A service for publishing HTML pages and static sites: upload a file or paste your code — get a public link like https://mypage.htmlkin.io in 10 seconds. No account and no hosting. AI assistants (Claude, Cursor and other MCP clients) publish sites on their own — through the MCP server https://htmlkin.io/mcp or the REST API. Key facts: - Anonymously, without an account: 1 site up to 20 MB, the link lives for 24 hours. - After a free sign-up a site lives as long as people visit it: 30 days without visits move it to the archive, and it can be restored from the dashboard within another 30 days. - Formats: a single HTML file, a static site (folder or ZIP; the entry page is index.html in the root, otherwise the first HTML file in the root). - Every site lives on its own {name}.htmlkin.io subdomain over HTTPS; a custom domain can be connected on any plan, including the free one — one DNS record, the SSL certificate is issued automatically. - The REST API and the MCP server are available on every plan, including Free: all you need is an account. ## Documentation - [Home](https://htmlkin.io/en): what the service does and the publishing form. - [Pricing](https://htmlkin.io/en/pricing): prices, limit comparison, payment FAQ. - [Examples](https://htmlkin.io/en/examples): a selection of sites published on htmlkin. - [REST API documentation](https://htmlkin.io/en/docs/api): endpoints, cURL/Python/JavaScript samples, error codes. - [OpenAPI 3.1](https://htmlkin.io/api/v1/openapi.json): the machine-readable REST API specification. - [MCP server setup](https://htmlkin.io/en/docs/mcp): connecting Claude, Claude Code, Cursor and other MCP clients. - [Browser extension](https://htmlkin.io/en/extension): publishing HTML from a ChatGPT chat in one click, or from any tab through the extension popup. - [llms-full.txt](https://htmlkin.io/llms-full.txt): the full API and MCP documentation in a single file. ## Plans and limits - Without an account — 1 site for 24 hours, uploaded by hand through the form on the site. - Free (no charge): 1 site, 20 MB storage, custom domains included. - Pro ($9.99/mo billed monthly; $99.90 billed once a year, 2 months free): 10 sites, 1 GB storage, custom domains included, PIN protection included, QR code generation included, 10 forms for lead collection with unlimited submissions. - Business ($19.99/mo billed monthly; $199.90 billed once a year, 2 months free): Unlimited sites, 5 GB storage, custom domains included, PIN protection included, QR code generation included, unlimited lead forms and submissions. ## Blog - [htmlkin blog](https://htmlkin.io/en/blog): guides, tests and comparisons for sharing HTML pages — all posts by category. - [Category: Guides](https://htmlkin.io/en/blog/category/guides): Step-by-step guides: sharing HTML pages and sites online, choosing hosting for static files. - [Category: AI](https://htmlkin.io/en/blog/category/ai): Presentations, landing pages and reports made with Claude and ChatGPT: how to build them and share them as a link. - [Category: Comparisons](https://htmlkin.io/en/blog/category/vs): htmlkin compared with other tools and approaches. - [Category: Using htmlkin](https://htmlkin.io/en/blog/category/how-to-use): Setting up htmlkin features step by step: custom domains, the REST API, publishing from GitHub. - [Claude artifacts alternative: where to share, build or host the page](https://htmlkin.io/en/blog/claude-artifacts-alternative): Compare 15 Claude artifacts alternatives: share the page with anyone, build it in another assistant, or turn it into an app with a database and sign-in. - [How to connect a custom domain to htmlkin](https://htmlkin.io/en/blog/connect-custom-domain): Step by step: point your own domain to an htmlkin page with an A record or a CNAME.
