StackEdit
Verified working Sep 22, 2026
A browser Markdown workspace with preview, sync, and publishing.
StackEdit is an open-source Markdown editor that runs in the browser and provides a split writing-and-preview workflow. It supports multiple Markdown flavors, offline writing, cloud synchronization, collaborative workspaces, inline comments, and publishing to several blogging or help-desk platforms.
Why it stands out
- Combines a full Markdown editor with browser-based offline use, reducing the need for a separate desktop app.
- Connects both storage services and publishing destinations, so drafts can move from Markdown to web platforms.
- Supports advanced Markdown-adjacent content such as LaTeX math, diagrams, music notation, and emoji.
- Built on PageDown, the editor lineage associated with Stack Overflow-style Markdown editing.
- Open-source and licensed under Apache License, making the project auditable and reusable.
Good to know
- Sync and collaboration rely on connecting supported external services such as Google Drive, Dropbox, or GitHub.
- Publishing integrations are limited to the platforms named by the project, such as Blogger, WordPress, and Zendesk.
- Advanced extensions like UML diagrams, ABC notation, or LaTeX may not render the same way in every Markdown destination.
Under the radar: When publishing, use the Handlebars output option if the destination’s Markdown renderer does not support the same extensions you used in StackEdit.
