stackedit

StackEdit is a full-featured Markdown editor that runs entirely inside your web browser. Markdown is a simple way of formatting text — you use plain characters like asterisks and hashes to indicate bold, headings, links, and so on, and the editor shows you a formatted preview in real time. It's the same Markdown library used by Stack Overflow.

The editor works in the browser without installing anything, making it accessible on any device. It connects with cloud storage services like Google Drive, Dropbox, and GitHub, so you can save and sync your documents without managing files manually. It also supports publishing directly to platforms like Blogger and GitLab. A separate embeddable version called stackedit.js lets developers add the editor to any website.

You'd use StackEdit when you want a comfortable writing environment for Markdown — drafting blog posts, documentation, or notes — and want cloud sync and publishing built in without leaving the browser. Developers who want to add a polished Markdown editing experience to their own app can embed it via the stackedit.js library. The project is built with JavaScript and can also be self-hosted on a server or a Kubernetes cluster for teams that want to run their own private instance.
