Note Mark is a lightweight web application for writing, organizing, and sharing Markdown notes. It focuses on speed and a minimal interface, with a responsive UI suited to both desktop and mobile use.
Key Features
- GitHub Flavored Markdown editing and rendering
- Fast editor with keyboard shortcuts and multiple viewing modes (rendered/plain)
- HTML sanitization to reduce XSS risks when rendering notes
- Notebook sharing with friendly, clean URLs
- Light and dark themes
- Upload and attach assets to notes
- Flat-file based storage system (no database required)
- Optional OpenID Connect (OIDC) support for single sign-on
Use Cases
- Personal or team Markdown note-taking with a clean web UI
- Shared notebooks for project notes, runbooks, or lightweight documentation
- Hosting a simple knowledge space with attachments and readable URLs
Limitations and Considerations
- The project’s V0.x line is in a maintenance-focused phase while V1 is being developed, which may affect feature velocity.
Note Mark is a solid choice if you want a fast, self-contained Markdown notes app with sharing, attachments, and optional SSO. Its flat-file storage and minimal design make it particularly appealing for simple deployments and homelab setups.
