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.

Janus Gateway

  • No commercial pricing published; open-source project without official commercial offerings
  • Community-supported only; no vendor commercial support or SLA available

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.

Janus Gateway: How much does Janus Gateway cost?

Janus Gateway has no pricing model; it is a free open-source WebRTC server developed by Meetecho. The general-purpose server is available for download at no cost. There are no subscription tiers or commercial licensing fees.

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.

Janus Gateway: Is Janus Gateway supported commercially?

Janus Gateway is community-supported open-source software with no official commercial support or SLA from the vendors. While Meetecho developed the project, users must rely on community documentation and forums for assistance.

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.

Docsify: Can I add versioned documentation?

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