Markdown has become the universal language for documentation, README files, blog posts, notes, and technical writing. If you write anything on the internet, you probably use Markdown. But choosing the right editor matters more than most people think. A good editor saves you hours per week through live preview, keyboard shortcuts, and seamless export options.
We tested every major Markdown editor available in 2026 and narrowed it down to 12 that are genuinely free (not "free trial" or "free with watermarks"). Here is how they compare.
| Editor | Type | Live Preview | Export | Best For |
|---|---|---|---|---|
| SPUNK.CODES Markdown Editor | Online | Yes | HTML, PDF, MD | Quick editing, no signup |
| StackEdit | Online | Yes | HTML, MD | Google Drive sync |
| Dillinger | Online | Yes | HTML, PDF, MD | Cloud storage integration |
| HackMD / CodiMD | Online | Yes | HTML, PDF | Collaborative editing |
| Editor.md | Online | Yes | HTML | Embeddable editor |
| Typora | Desktop | Inline | HTML, PDF, DOCX, EPUB | Distraction-free writing |
| Obsidian | Desktop | Yes | PDF, MD | Note-taking, knowledge base |
| Mark Text | Desktop | Inline | HTML, PDF | Open source alternative to Typora |
| Zettlr | Desktop | Yes | HTML, PDF, DOCX, ODT | Academic writing |
| VS Code + Extensions | Desktop | Yes | HTML, PDF | Developers, integrated workflow |
| Ghostwriter | Desktop | Yes | HTML | Minimal, focus mode |

Price: Free, no signup — Platform: Any browser
Our own Markdown Editor is built for speed. Open the page, start typing, see your preview instantly. No account creation, no cloud storage requirements, no tracking. Everything runs in your browser.
Features include live side-by-side preview, syntax highlighting, one-click export to HTML and raw Markdown, word count, and support for GitHub Flavored Markdown (GFM) including tables, task lists, and code blocks with language highlighting.
Price: Free — Platform: Browser
StackEdit has been around for years and remains one of the most polished online Markdown editors. It syncs with Google Drive, Dropbox, and GitHub. The editor supports WYSIWYG controls, KaTeX math expressions, UML diagrams, and custom templates.
The offline support through service workers means you can keep writing without internet. Workspaces let you organize documents into projects. The main downside is that the interface feels slightly dated compared to newer editors, and some features require a Google account.
Price: Free — Platform: Browser
Dillinger takes the minimal approach. Two panes: Markdown on the left, preview on the right. It connects to GitHub, Dropbox, Google Drive, OneDrive, and Medium. Export to HTML or styled PDF with one click.
The interface is clean and distraction-free. It handles large documents well, which is a problem for some browser-based editors. The GitHub integration is particularly smooth for developers writing README files.
Price: Free (with paid tiers) — Platform: Browser, self-hosted
HackMD is the go-to for collaborative Markdown editing. Multiple people can edit the same document in real time, similar to Google Docs. It supports slide mode (create presentations from Markdown), book mode (multi-page documents), and has excellent code block support with syntax highlighting for 150+ languages.
CodiMD is the self-hosted open source version. If you want the same features without depending on HackMD's servers, you can run it on your own infrastructure.
Price: Free, open source — Platform: Browser (embeddable)
Editor.md is designed to be embedded in other applications. If you are building a platform that needs Markdown editing (a CMS, wiki, or documentation tool), Editor.md gives you a full-featured editor as a JavaScript component. It includes a toolbar, live preview, image uploading, emoji support, and flowchart/sequence diagram rendering.
Price: $14.99 one-time (free trial available) — Platforms: Windows, macOS, Linux
Typora is technically not free after the trial, but we include it because the one-time price is fair and the editor is exceptional. Its unique "inline preview" renders Markdown as you type. There is no separate preview pane — headings look like headings, bold text looks bold, and images display inline. It feels like writing in a rich text editor with the efficiency of Markdown.
Export options are extensive: PDF, HTML, DOCX, EPUB, LaTeX, and more via Pandoc integration. Custom themes let you match your preferred aesthetic.
Price: Free for personal use — Platforms: Windows, macOS, Linux, iOS, Android
Obsidian is a Markdown editor, but calling it just that undersells it dramatically. It is a knowledge management system that uses Markdown files as its foundation. Bi-directional linking between notes creates a graph of your knowledge. The plugin ecosystem has over 1,000 community plugins that extend functionality in every direction imaginable.
For pure Markdown editing, Obsidian is excellent. But its real power emerges when you use it as your second brain — connecting ideas, building a personal wiki, and creating a searchable knowledge base that grows with you.
Price: Free, open source — Platforms: Windows, macOS, Linux
Mark Text is the open source answer to Typora. It offers the same inline rendering approach where Markdown is displayed as formatted text as you type. Built on Electron, it supports six themes (three light, three dark), focus mode, typewriter mode, and source code mode.
Table editing is particularly well done, with a graphical table editor that feels natural. The export options cover HTML and PDF. The project is actively maintained and has a growing community.
Price: Free, open source — Platforms: Windows, macOS, Linux
Zettlr targets academic writers and researchers. It integrates with Zotero for citation management, supports footnotes natively, and exports to academic formats through Pandoc. The Zettelkasten method support (linking notes with unique IDs) makes it popular with researchers building interconnected note systems.
Beyond academia, Zettlr works well for any long-form writing. The distraction-free mode, project management features, and word count targets help keep writing on track.
Price: Free — Platforms: Windows, macOS, Linux
If you already use VS Code for development, it is an excellent Markdown editor with the right extensions:
The integrated terminal means you can write, preview, and commit your Markdown files without switching applications. For developers writing documentation alongside code, this is the most efficient setup.
Price: Free, open source — Platforms: Windows, Linux
Ghostwriter is built for distraction-free writing. The focus mode dims everything except the current paragraph. The Hemingway mode disables backspace and delete, forcing you to write forward instead of editing as you go. These features sound gimmicky but genuinely improve writing speed for many people.
The built-in theme editor, outline sidebar, and live word count statistics round out a clean, focused editor. The only downside is no macOS support.
Price: Free — Platforms: Windows, macOS, Linux
Notable organizes Markdown files using tags instead of folders. This means a single note can belong to multiple categories without duplication. The split editor with live preview works smoothly, and the search is fast even with thousands of notes.
Notable stores everything as plain Markdown files in a regular folder, so you are never locked into the application. You can open the same notes folder with any other editor.
For quick reference, here are the most common Markdown patterns:
# Heading 1 ## Heading 2 ### Heading 3 **bold text** *italic text* ~~strikethrough~~ - Bullet list - Another item - Nested item 1. Numbered list 2. Second item [Link text](https://url.com)  `inline code` ```javascript // Code block with syntax highlighting const greeting = "Hello, World!"; ``` | Column 1 | Column 2 | |----------|----------| | Cell 1 | Cell 2 | > Blockquote text --- Horizontal rule
Test any of these patterns instantly with our free Markdown Editor. No signup needed.
For quick one-off edits: Use an online editor like ours or Dillinger. No installation, no signup.
For daily writing: Choose a desktop editor. Obsidian for knowledge management, Typora or Mark Text for clean writing, Zettlr for academic work.
For development teams: VS Code with extensions keeps everything in one place. HackMD adds real-time collaboration.
For documentation projects: HackMD or Obsidian with the Git plugin. Both support collaboration and version control.
