The short version

  • Each has a real cost: Docsify pages are assembled by JavaScript at runtime, so search engines and crawlers that do not execute scripts see an empty shell, which makes it unsuitable for documentation that must be found through search.; Obsidian sync is a paid add-on at $4 per month billed annually rather than part of the app
  • They diverge on capability: Docsify covers No build step, Obsidian covers Bidirectional linking.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Docsify

  • Pages are assembled by JavaScript at runtime, so search engines and crawlers that do not execute scripts see an empty shell, which makes it unsuitable for documentation that must be found through search.
  • Every page view fetches markdown files over the network and renders them client-side, so on slow connections the site is visibly slower than pre-generated HTML.
  • Full-text search is built in the browser from all your documents, and the index becomes slow to build and heavy to hold once a site grows past a few dozen pages.
  • There is no built-in versioning, so supporting several releases of a product means directory conventions and hand-maintained sidebars.
  • The plugin ecosystem is loaded through script tags with no dependency management, so plugins break silently against new core versions and there is no build to catch it.

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

Docsify: Is Docsify bad for SEO?

Yes, by design. There is no static HTML for a crawler to read unless you add prerendering, which reintroduces the build step the tool exists to avoid. Choose a static generator if search traffic matters.

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.

Source
Docsify: Does it need Node.js to run?

Only for the local preview command. The published site is static files served by any web server, including GitHub Pages.

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.

Source
Docsify: How large a documentation set can it handle?

Comfortably a few dozen pages. Beyond that, client-side search and sidebar maintenance become the limiting factors rather than rendering speed.

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.

Source
Docsify: Can I add versioned documentation?

Not natively. The usual approach is a directory per version with its own sidebar, maintained manually.
