How close is the rendering to what I’ll see on GitHub or GitLab?

dochost renders CommonMark-compatible Markdown, which covers the vast majority of what GitHub Flavored Markdown produces: headings, fenced code blocks with language hints, tables, task lists, blockquotes, and inline formatting. A small number of GitHub-specific extensions — such as repository-relative image paths or @mention links — will not resolve, because those depend on GitHub’s own context. For prose, structure, and code, the rendered output is a reliable stand-in.

Do I need an editor plugin or desktop app to get a rendered preview?

No installation is required. dochost runs entirely in the browser, so you can preview Markdown on any machine that has a web connection — including a locked-down work laptop where you cannot install extensions, a colleague’s computer, or a shared device. Paste your Markdown source into the tool, and the rendered page appears immediately. There is no account to create and nothing to configure before you can see the output.

Will the preview look right on a phone or tablet?

Yes. The published page uses a responsive layout, so the rendered Markdown reflows for smaller screens rather than displaying as a shrunken desktop view. This is particularly useful for catching issues — wide tables, long code lines, or misleveled headings — that are hard to notice in a desktop editor but immediately obvious on a narrow phone screen. Checking the preview URL on your phone before merging is a low-effort way to catch layout problems early.

Can I send the preview to someone else, or is it only for my own review?

The preview is a real URL that anyone with the link can open — no account, no login, no app download needed on their end. You can paste it into Slack, a PR comment, an email, or a GitHub issue and the recipient sees the same rendered page you see. Free links stay live for seven days, which is plenty of time for a pre-merge review cycle. If you need the link to remain active permanently, a paid plan keeps it live indefinitely.

Pasting Markdown into an editor and squinting at the raw syntax is not the same as seeing what your readers will see. A real markdown preview — a markdown live preview that updates as you paste — renders headings, code blocks, tables, and inline formatting exactly as they appear in a browser — not as a wall of asterisks and backticks. dochost turns any Markdown you paste into a clean, shareable page in seconds. No editor plugin to install, no account required to start. Paste your content, check how it renders on any device, and send the link to whoever needs to sign off — all before a single line is merged.

Preview and share Markdown in three steps

1. Paste your raw Markdown source into the editor — no formatting or conversion needed beforehand.
2. dochost renders it instantly so you can check headings, tables, code blocks, and layout on any screen size.
3. Copy the generated URL and share it with teammates for feedback before you merge or publish.

A real example

Yuki is a technical writer at a developer-tools company. She has spent the afternoon updating the README for an open-source library: rewriting the installation section, adding a configuration table, and reworking the contributing guide into a numbered list. The PR is ready, but before she requests a review she wants to see the rendered result on her phone — because that is how a lot of contributors will actually read it.

She copies the entire README source, opens dochost, pastes it into the markdown tool, and hits publish. Within a couple of seconds she has a URL. She opens it on her phone and immediately spots two problems: one heading level is off, making the hierarchy look wrong in mobile view, and a table column is wider than she intended, causing it to scroll horizontally. She fixes both in the PR, re-pastes, and gets a new preview link.

She then sends the updated link to her engineering lead with a Slack message: “Can you check that the config table reads clearly?” He clicks the link from his laptop, skims the rendered page in under a minute, and replies with one small wording tweak. No back-and-forth about raw syntax, no asking him to clone the repo — just a URL pointing to exactly what the merged README will look like.
