Eight editors honestly compared — free online tools, developer setups, note-taking apps, and writing-focused software — with pricing, platforms, and who each one is actually for.
The best Markdown editor depends on your workflow: a free online editor (like the MarkdownTools editor or StackEdit) for quick edits with no install, VS Code for developers, Obsidian for linked notes, and Typora or iA Writer for distraction-free long-form writing. Because Markdown files are plain text, you can switch editors at any time with zero lock-in.
Every editor below handles standard Markdown well — headings, emphasis, lists, links, code, tables — so the real differences are workflow: where it runs, whether it works offline, how the preview behaves, and what it costs. We list our own editor first because it is the fastest to start with, but we have tried to be straight about where each tool (including ours) falls short.
New to the syntax itself? Work through the Markdown tutorial first — it takes about 30 minutes — and keep the cheat sheet handy while you write.
Our own free in-browser editor: open markdowntools.io/editor and start typing — no signup, no install. You get a live side-by-side preview, autosave in your browser, a document outline, find & replace, and shareable links. It is a writing and editing surface rather than a full notes system, so there is no folder tree or plugin ecosystem — for quick drafts, READMEs, and cleaning up documents it is the fastest option on this list.
Microsoft's free code editor ships with a built-in Markdown preview (Ctrl/Cmd+Shift+V), and extensions like Markdown All in One and markdownlint add shortcuts, table formatting, auto-generated tables of contents, and linting. It is overkill if you only write prose, but if you already live in VS Code for code, it is the natural place to write docs too.
A local-first knowledge base built on plain Markdown files. Notes link to each other with wiki-style links, a graph view shows connections, and a huge community plugin ecosystem covers everything from calendars to spaced repetition. Your notes stay on your device as ordinary .md files, which makes it one of the most future-proof choices for a personal notes system.
A minimal desktop editor famous for its seamless live rendering: there is no split view — the Markdown formats in place as you type, so the document always looks like the finished result. It also handles tables, math, and diagrams gracefully and exports to PDF, HTML, and Word. It is a one-time purchase (around $15) with a free trial.
A free, open-source in-browser editor with a classic split-pane preview. Its standout feature is workspace sync: it can save documents to Google Drive, Dropbox, GitHub, and other services, and it works offline as a browser app. The interface feels a little dated, but the feature set is generous for a free web tool.
A simple, free online Markdown editor with a live preview and one-click export to HTML, PDF, and styled formats. It can import from and save to Dropbox, GitHub, Google Drive, and OneDrive. There is no account required for basic use — it is a solid pick when you just need to preview or convert a document quickly.
A beautifully designed writing app with careful typography, a focus mode that dims everything but the current sentence, and syntax highlighting that marks adjectives, verbs, and repetitive words. It is a paid app purchased per platform, aimed squarely at writers who care about the writing experience more than technical features.
A free, open-source editor built for academic and research writing. It integrates with Zotero for citations, supports CSL bibliographies and footnotes, and is designed around the Zettelkasten note-taking method. It has a steeper learning curve than the others here, but for papers and theses written in Markdown it is hard to beat at the price of free.
All eight editors at a glance. "Offline" means you can write without an internet connection; "Live preview" covers both split-pane and in-place rendering.

|---|---|---|---|---|---|
| MarkdownTools Editor | Free | Web | Yes (split pane) | No | Autosave, outline, share links |
| VS Code | Free | Win / Mac / Linux | Yes (split pane) | Yes | Extensions, linting, git |
| Obsidian | Free (paid sync) | Desktop + mobile | Yes (live) | Yes | Wiki links, graph, plugins |
| Typora | ~$15 one-time | Win / Mac / Linux | Yes (in-place) | Yes | Math, diagrams, export |
| StackEdit | Free | Web | Yes (split pane) | Partially | Drive / GitHub sync |
| Dillinger | Free | Web | Yes (split pane) | No | HTML / PDF export |
| iA Writer | Paid | Mac / iOS / Win / Android | Yes (toggle) | Yes | Focus mode, style check |
| Zettlr | Free | Win / Mac / Linux | Yes (live) | Yes | Citations, Zettelkasten |
Don't overthink it — since Markdown files are portable plain text, a "wrong" choice costs you nothing but the time to download a different app. Match the editor to what you actually do most:
Use a web editor — nothing to install and you are typing in seconds. The MarkdownTools editor adds autosave and shareable links; Dillinger is handy when you mainly need an HTML or PDF export.
Obsidian is the default choice: local Markdown files, wiki links between notes, and plugins for almost anything. Zettlr is the open-source alternative if you follow the Zettelkasten method or write with citations.
VS Code wins if you already use it — your docs live next to your code, versioned in git, with linting and preview built in. Pair it with the cheat sheet for the GitHub-flavored extras like task lists and tables.
Typora and iA Writer are the most pleasant places to write prose: Typora renders formatting in place as you type, while iA Writer adds focus mode and style feedback. Both export cleanly to HTML and PDF.
Not sure yet? Start in the browser — free, no signup, live preview, autosave — and move to a desktop app later if you outgrow it.
Open the free Markdown editor →It depends on where you work. In the browser, the MarkdownTools editor and StackEdit are both free with live preview. On the desktop, VS Code is the best free option for developers, Obsidian for note-takers, and Zettlr for academic writing. All of them are genuinely free, not trials.
For quick writing and editing, the free MarkdownTools editor gives you a live preview, autosave, outline navigation, and shareable links with no signup. StackEdit is the strongest choice if you want your documents synced to Google Drive or GitHub, and Dillinger is good for fast HTML and PDF exports.
No. Markdown files are plain text, so any editor — even Notepad — can open and edit them. Dedicated Markdown editors just add conveniences: live preview, formatting shortcuts, export options, and syntax highlighting. Start with a free one and only pay if a specific feature earns it.
No. Typora offers a free trial, but after that it is a paid one-time purchase of roughly $15 per license. There is no subscription — you buy it once. If you want the same minimal in-place rendering style for free, Obsidian in live-preview mode comes close.
Mostly VS Code, because documentation usually lives in the same repository as the code. The built-in preview plus extensions like Markdown All in One and markdownlint cover shortcuts, tables of contents, and style checking. Obsidian is also popular with developers for personal notes.
Yes. Obsidian has full-featured iOS and Android apps, and iA Writer runs on iOS and Android as a paid app. Browser-based editors also work on mobile in a pinch, though writing Markdown syntax on a phone keyboard is slower than on a desktop.
Markdown files are plain .md text files, so there is no lock-in: a document written in Typora opens identically in VS Code, Obsidian, or a web editor. Switching editors later costs nothing, which is exactly why Markdown is a safe format for long-lived notes and docs.
