+---
+
+[dochost](https://dochost.io) is a free, online tool that turns Markdown or HTML into a hosted, shareable link. Like [StackEdit](/tools/stackedit/) and [Dillinger](/tools/dillinger/), it loads right in your web browser, so there's no need to download and install an application. You paste or write Markdown, see a live preview, and publish the document to a public URL — no signup required.
+
+dochost renders [GitHub Flavored Markdown](https://github.github.com/gfm/), including tables, task lists, strikethrough, and footnotes, and highlights fenced code blocks with [Shiki](https://shiki.style/). In addition to Markdown, it can host a full HTML page and return a shareable link, which makes it useful for quickly sharing rendered notes, documentation, and snippets.
