- Educators sharing real-time lecture notes
- Privacy-conscious users replacing SaaS note apps
Detailed Introduction
HedgeDoc (formerly CodiMD) lets you create real-time collaborative Markdown notes. It's the open-source self-hosted alternative to HackMD, designed for teams and communities who want full control over their data. Features include live preview, diagram support (Mermaid, Graphviz), LaTeX math, slide mode, and version history. The current 2.0 rewrite brings a modern stack (NestJS + React) with enhanced performance and extensibility. HedgeDoc 1.x remains stable but is in maintenance-only mode. Ideal for developers, educators, and organizations needing a private, real-time collaborative writing platform.
