Files you own
Every note is a Markdown file with YAML frontmatter, in a folder you choose, readable by Obsidian and any text editor. Export never loses text.
Nether
Nether is self-hostable and local-first note taking app combining both Notion and Obsidian features. You can import your Obsidian vaults and Notion exports. Self-hosting is available for enterprise.
Structure when you want it
The same notes become databases, with table, board, calendar, timeline, gallery and list views, relations and formulas.
A server you run
Sync, sharing and real-time co-editing come from a server you start with one docker compose up, or from no server at all.
Free, all of it
One open-source license, the AGPL, covers everything, enterprise features included. No paid editions, no license keys.
