HedgeDoc vs Markra

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.

Markra is a local-first, open-source Markdown workspace with native AI review, offered as a desktop app and web editor. It supports WYSIWYG and source editing, with inline rendering for links, images, tables, tasks, callouts, code, math, and Mermaid diagrams. Users can open files or folders and keep local files, tabs, and rich editing together; documents remain ordinary Markdown files, and writing does not require an account. AI can answer questions, rewrite or summarize text, and propose edits, but users must approve changes before they are applied. AI features require at least one configured provider, including cloud providers, Ollama, or OpenAI-compatible endpoints. Provider API keys and custom headers are stored in local settings, and exported settings can include them. Notes can optionally sync through WebDAV, which preserves conflict copies. Desktop downloads are available for macOS, Windows, and Linux. Desktop exports include HTML, PDF, and Pandoc formats when configured; the web editor supports HTML download and browser print or PDF. Core features are free; AI use requires a configured provider.
