- Markdown only, so embedding interactive components is not the model
Obsidian
- Sync is a paid add-on at $4 per month billed annually rather than part of the app
- Publishing to the web is a further $8 per month per site
- Commercial use asks for a $50 per user per year licence, though the vendor states it is not required
- Collaboration is limited compared with a hosted notes tool, since the vault is local files first

Answered from the vendors’ own pages
MkDocs: Is MkDocs free?
Yes, open source under the BSD licence. The Material theme has a free version and a paid Insiders edition.
Obsidian: Is Obsidian free?
Yes. The core Obsidian application is 100% free for personal and commercial use with no limitations. You can use unlimited vaults and every core feature without payment.
SourceMkDocs: MkDocs or Docusaurus?
MkDocs is simpler and faster to adopt, especially for Python teams. Docusaurus offers versioning, internationalisation and React components, which matter once documentation grows.
Obsidian: What file format does Obsidian use?
Obsidian stores every note as a plain Markdown file. Because it uses standard Markdown instead of a proprietary format, your notes remain portable and can be edited with many other Markdown editors.
SourceMkDocs: Does MkDocs support versioned docs?
Not natively. Plugins such as mike add it, where Docusaurus includes versioning in core.
Obsidian: Can I collaborate with others in Obsidian?
The core application does not include built-in team collaboration features. However, Obsidian offers optional add-ons and can be used with version control systems or cloud storage for collaboration.
