CodiMD is a self-hosted, open-source web application for real-time collaborative markdown note editing, built from the HackMD source code. It supports slide and presentation modes, multiple authentication providers (OAuth, SAML, LDAP), and Docker or Kubernetes deployment.

Use cases

• host a self-hosted collaborative markdown editor for my team
• take shared meeting notes in real time in the browser
• self-host an alternative to HackMD or Notion for docs
• write markdown documents collaboratively with live editing
• create slide presentations from markdown
• own my team's documentation data on my own server

When to choose

• you want a free, self-hosted HackMD alternative where you control all data
• your team or community needs realtime collaborative markdown notes
• you need SSO via OAuth, SAML, or LDAP for a docs platform
• you want markdown-based slides or book-style docs

When to avoid

• you need commercial features like book mode and fine-grained permission controls that only HackMD offers
• you need a lightweight single-user markdown editor without a server
• you cannot run a Node.js service or Docker container
