What is the Markdown editor?

This Markdown editor lets you write plain-text documentation on one side and inspect sanitized HTML on the other without leaving the browser. It is useful for README files, release notes, runbooks, and other technical docs that need a quick render check before publishing.

How the Markdown editor works

The page can load a built-in preset or query-backed Markdown draft into the editor, then parse that Markdown in the browser and sanitize the resulting HTML before previewing it. Ongoing edits can stay local in browser storage, and the draft only moves into a URL when you explicitly copy a share link.

Common Use Cases
  • Writing project README files
  • Drafting release notes and changelogs
  • Preparing incident runbooks
  • Previewing Markdown used in Git platforms
  • Checking code block, table, and link formatting
