FlatNotes
Self-hosted markdown notes that live on disk as plain .md files — no SQL database, no proprietary export, your notes survive every app you'll ever stop using.
A managed instance of FlatNotes on ElfHosted — a deliberately minimal markdown notes server where every note is a flat .md file. Edit in the web UI, or sync the notes folder with Syncthing/rclone and edit in Obsidian / VS Code / vim. Full-text search, tags via #hashtags inside notes, dark mode. MIT-licensed.
