我发现markdownlivepreview.com非常接近于香草GitLab markdown。 其他查看器对命令的解释与GitLab略有不同。

对于那些希望在ipad上开发游戏的人来说，我喜欢Textastic。您可以编辑和预览README。Md文件，没有互联网连接，一旦你从云下载文档。

你可以使用静态网站编辑器:在GitLab 13.0(2020年5月)中，它附带了一个所见即所得面板。

WYSIWYG for the Static Site Editor Markdown is a powerful and efficient syntax for authoring web content, but even seasoned authors of Markdown content can struggle to remember some of the less-frequently used formatting options or write even moderately-complex tables from scratch. There are some jobs better accomplished with a rich text, “What You See Is What You Get” (WYSIWYG) editor. GitLab 13.0 brings a WYSIWYG Markdown authoring experience to the Static Site Editor with formatting options for common formatting options like headers, bold, italics, links, lists, blockquotes, and code blocks. The WYSIWYG editor also removes the onerous task of editing tables in Markdown by letting you visually edit table rows, columns and cells in the same way you would edit a spreadsheet. For those more comfortable writing in raw Markdown, there’s even a tab for switching between WYSIWYG and plain text editing modes.

请参阅文档和版本。

同样，您只能使用它来编写README:一旦它看起来很好，您就可以将它报告给原始项目。 但重点是:你不需要任何第三方降价预览插件。

GitLab 14.2(2021年8月)

Preview Markdown live while editing Markdown is a fast and intuitive syntax for writing rich web content. Until it isn’t. Luckily, it’s easy to preview the rendered output of Markdown to ensure the accuracy of your markup from the Preview tab. Unfortunately, the context switch required to move between the raw source code and the preview can be tedious and disruptive to your flow. Now, in both the Web IDE and single file editor, Markdown files have a new live preview option available. Right-click the editor and select Preview Markdown or use Command/Control + Shift + P to toggle a split-screen live preview of your Markdown content. The preview refreshes as you type, so you can be confident that your markup is valid and will render as you intended. See Documentation and Epic.

Toggle wiki editors seamlessly Toggle wiki editors seamlessly Editing wiki pages with the new rich Markdown editor makes it easier for everyone to contribute regardless of how well they know Markdown syntax. You may also prefer to write raw Markdown in some situations, but use the WYSIWYG interface for more complex or tedious formatting tasks, like creating tables. Previous versions of GitLab required you to save changes before switching between the rich Markdown editor and the Markdown source, adding more steps and friction to your edits. In GitLab 14.6 you can now seamlessly switch between the two editing experiences without committing your changes, choosing the editor that suits your needs at any given moment. See Documentation and Issue.

Default split view for Markdown preview in the Web Editor The ability to preview Markdown files side by side while editing was introduced in GitLab 14.2. With this release, we’ve made the split view the default experience for previewing Markdown in the Web Editor. In the Preview tab, you can now see a live Markdown preview that updates as you type alongside your content. This way, you can be confident that your markup is valid and renders as you intended without having to switch between the Write and Preview tabs. See Documentation and Issue.

有很多方法:如果你用的是Mac，使用Mou。

如果您想在浏览器中测试，您可以尝试StackEdit，正如@Aaron或Dillinger指出的那样，因为Notepag现在似乎已经关闭了。就我个人而言，我使用Dillinger，因为它可以将我所有的文档保存在浏览器的本地数据库中。

Visual Studio Code具有编辑和预览md文件更改的选项。因为VS Code是独立于平台的，所以这适用于Windows、Mac和Linux。

要在视图之间切换，请在编辑器中按Ctrl+Shift+V。您可以与正在编辑的文件并排查看预览(Ctrl+K V)，并在编辑时查看实时反映的更改。

也……

问:VS Code是否支持GitHub调味Markdown? 答:不，VS Code使用Markdown -it库来实现CommonMark Markdown规范。GitHub正在向CommonMark规范迈进。

Atom工作得很好-只需打开Markdown文件，并按Ctrl+Shift+M切换Markdown预览面板旁边。它还处理HTML和图像。
