Obsidian
Local Markdown notes
freemiumProductivity
Obsidian is a knowledge base over a plain folder of Markdown files: bidirectional links, a connection graph, and hundreds of plugins. Your files stay yours forever — put them in git or iCloud. Free for personal use; their sync service is a paid option.
// Install
Your MacHomebrew in /opt/homebrew
brew install --cask obsidian// What it is for
- Notes are plain markdown files on your disk: they outlive any service and open in any editor
- Backlinks and a graph view — the knowledge base grows structure on its own
- Fully offline, with syncing your choice: git, iCloud, or the paid Sync
- Plugins cover the rest: tasks, tables, diagrams, publishing
// Common questions
Obsidian or Notion?
Obsidian means local files, offline access, and full control, but weaker collaboration. Notion means cloud and teamwork, but your notes live on someone else's servers. For a developer's personal knowledge base, Obsidian is the safer bet.
What does Obsidian cost?
Personal use is free with no limits. The paid parts are Sync and Publish — both replaceable with git and static hosting.
