Leafdown is an open-source, local-first Markdown desktop app for ordinary files and folders. It is built for quickly opening, reading, and editing Markdown without adopting a vault, workspace, cloud service, or IDE.
The initial internal alpha has been released. Leafdown remains under active development and is not yet packaged for broad redistribution.

- Handles dirty documents, recent files and folders, local links, local images, and filesystem watcher refreshes.
- Runs offline without accounts, telemetry, cloud sync, or project metadata in opened folders.
