The right markdown editor depends on what you're building. Writing a quick README? A browser-based editor is fine. Working on a novel? You want a desktop app with offline support. Managing a team blog? You need something connected to your publishing workflow.
This list covers editors for different use cases, not just one winner.
What makes a good markdown editor
Before picking a tool, it helps to know what to look for:
- Live preview or rendered output alongside the editor, so you catch formatting issues without switching contexts
- GFM support (tables, task lists, strikethrough, fenced code blocks), since GitHub Flavored Markdown is the de facto standard
- File management or auto-save for longer writing sessions where losing work is not an option
- Export options (HTML, PDF, .docx) if your output needs to leave the markdown ecosystem
- Speed: markdown tools should feel instant; a loading spinner defeats the purpose
The editors
md0 Editor
md0.io/editor is a free browser-based editor with live preview, GFM support, and browser auto-save. No account required, no install. Good for quick drafts, sharing snippets, or writing when you're not at your usual machine. It handles single documents only; there's no folder management or file sync, so it's not the right tool for a long-running project with multiple files.
md0 Live Editor
md0.io/live-editor shows markdown source on the left and rendered output on the right in a split-pane layout. Functionally identical to the standard editor; the difference is the layout. Writers who want to keep an eye on the rendered output while typing tend to prefer this view. Same limitations apply: single-document, browser-only.
Obsidian
Obsidian is a desktop app for Mac, Windows, and Linux that organizes markdown files into vaults: folders that Obsidian treats as a self-contained knowledge base. It's built for personal knowledge management and long-form writing. The plugin ecosystem is large: graph views, templating, kanban boards, and publishing tools are all available. Works fully offline. The core app is free; the sync feature costs $4/month. If you're building a personal notes system or writing a book, Obsidian is one of the strongest options available.
Typora
Typora ($15, one-time purchase) takes a different approach: markdown renders inline as you type, so the document looks like the output rather than a source file. There's no split pane. Bold text looks bold; headers look like headers. Writers who find raw markdown syntax distracting tend to stick with Typora. The UI is clean and minimal. It supports Windows, Mac, and Linux.
VS Code
VS Code is a free code editor with strong built-in markdown support and an even stronger extension ecosystem. The Markdown All in One extension adds shortcuts, table formatting, and a table of contents generator. Markdown Preview Enhanced adds more advanced rendering options. If you already use VS Code for development, it's a capable markdown editor with no additional setup. It's less comfortable for non-technical writers who aren't already familiar with the interface.
iA Writer
iA Writer is a distraction-free writing app for Mac and iOS ($29.99 to $49.99 depending on platform). It enforces a minimal interface by design: no plugins, no customization, just the text. The focus mode dims everything except the sentence or paragraph you're editing. Files sync via iCloud. If your goal is to sit down and write without fiddling with settings, iA Writer removes the friction. The limited customization is intentional, not an oversight.
HackMD
HackMD is a browser-based collaborative markdown editor. Multiple people can edit the same document simultaneously, similar to Google Docs but in markdown. It's well-suited for teams drafting technical specifications, meeting notes, or documentation together in real time. The free tier includes collaboration but has limits on private notes. Paid plans start around $5/month per user.
Zettlr
Zettlr is a free, open source desktop app aimed at academic writers and researchers. It supports citations via BibTeX and Zotero, LaTeX math rendering, footnotes, and the Zettelkasten knowledge management method. It's more complex to set up than most editors on this list, but it's the right tool if you're writing papers, a thesis, or anything that requires proper citation management.
MarkText
MarkText is a free, open source desktop app for Mac, Windows, and Linux. It offers an inline preview mode similar to Typora and a focus mode for distraction-free writing. The interface is simpler than VS Code and less opinionated than iA Writer. Development is active but slower than some other projects. A solid choice if you want a desktop editor without paying for one.

Which one to pick
The right choice depends more on your workflow than on feature lists:
- Quick browser-based editing with no setup: md0 Editor or HackMD
- Daily writing on a Mac: iA Writer or Typora
- Developer workflows in an existing editor: VS Code
- Personal knowledge management with a large file library: Obsidian
- Academic writing with citations and references: Zettlr
- Real-time collaboration with a team: HackMD
If you want to get started without installing anything, try md0's online editor or the side-by-side live preview. For a syntax reference while you write, the markdown cheatsheet covers GFM syntax including tables, task lists, and code blocks.
