Stackedit

StackEdit is a browser-based Markdown editor designed for structured document authoring and collaborative content creation. It functions as an offline-first web application, allowing users to maintain full access to their documents and editing tools without an active internet connection, with changes automatically synchronized once connectivity is restored.

The platform distinguishes itself through its support for real-time multi-user collaboration, utilizing operational transformation to merge concurrent edits from multiple participants. It features a modular architecture that supports specialized content rendering, including mathematical expressions, diagrams, and musical scores, alongside a plugin-based system for extending Markdown syntax. Users can configure specific Markdown flavors to ensure compatibility across different technical environments.

Beyond its primary interface, the project provides an embeddable editor component that can be integrated into external websites via sandboxed frames. It includes built-in cloud storage adapters for file synchronization and publishing, and supports containerized deployment within cluster environments.
