Downright and Obsidian both work with Markdown files locally. Their mental models are different: Downright starts with the file you opened; Obsidian starts with a vault of linked notes.
Choose Downright if…
- Your source files already live in project folders, repositories, or agent workspaces.
- You want an exact renderer, a close Source view, and no database-like vault layer.
- You want external-write review when Claude Code or another coding agent changes an open file.
- You want a free MIT-licensed native Mac app without an account.
Choose Obsidian if…
- You want backlinks, graph navigation, plugins, and a knowledge-management workflow.
- You are happy to organize work inside one or more vault folders.
- You want optional Sync or Publish services across devices.
The practical difference
Obsidian is a strong choice for a connected personal knowledge base. Downright is a strong choice for reading and reviewing ordinary Markdown where the file path, raw bytes, and external changes matter. Both can be local-first. They optimize for different kinds of continuity.
