HedgeDoc vs Muesli

HedgeDoc is a free, open-source Markdown editor for collaborative notes, diagrams, and presentations. It runs in a browser and can be self-hosted. People can edit notes together in real time by sharing a link, and guests can access notes. Notes can include graphs, diagrams, and embedded content; Markdown slides can be presented using reveal.js. Revision history records changes and lets users restore earlier versions. HedgeDoc 1.x offers six note-permission settings, from open editing to private access, and only the note owner can change a note’s permission. Its documentation describes authentication integrations such as LDAP, OAuth, SAML, GitHub, GitLab, Keycloak, Mattermost, Nextcloud, and Microsoft Entra ID. Image uploads can use filesystem, Imgur, S3, MinIO, Azure, or Lutim storage. Deployment options include a ready-to-use bundle and an official Docker image for amd64 and arm64. Built-in PDF export is deactivated after security vulnerabilities; browser print-to-PDF is suggested instead. The source code is licensed under AGPL 3.0.

Muesli is a free, real-time collaborative Markdown editor for teams and AI agents working in the same plain .md file. Collaborators can see live cursors and presence, discuss material in comment threads, submit tracked suggestions, and use append-only history with snapshots. Editing tools include inline preview, a source toggle, KaTeX math, Mermaid diagrams, editable tables and callouts, wikilinks, and backlinks. Claude Code, Cursor, Codex, Copilot, and Gemini CLI can work through MCP or edit the file directly. When a human is present in a document, agent edits become suggestions for review. Guest links can grant viewer, commenter, or editor access without requiring accounts. Storage choices include local files, S3-compatible services, GitHub, Gitea, Forgejo, and Google Drive. Muesli is available on the web, Windows, macOS, Linux, and as a self-hosted service, and is open source under AGPL-3.0. Self-hosting uses one Docker image, but durable documents and history require Postgres and Redis. The hosted service says document contents remain in user-chosen storage and are not read, mined, or used for training.
