- They diverge on capability: Docsify covers No build step, HTMX covers AJAX requests.

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.
HTMX
- Best suited for server-rendered architectures, not pure client-side SPAs
- Limited client-side state management capabilities compared to frameworks
- Smaller ecosystem with fewer third-party libraries and tools
- Learning curve for developers from JavaScript framework backgrounds

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.
HTMX: How big is the HTMX JavaScript library?
HTMX is only 16 kilobytes minified and gzipped with zero external dependencies.
SourceDocsify: 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.
HTMX: Can HTMX work with JSON APIs?
While HTMX is optimized for HTML responses, it can work with JSON through additional configuration and response handling.
SourceDocsify: 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.
HTMX: Does HTMX support real-time features like WebSockets?
Yes, HTMX includes support for WebSockets and server-sent events for real-time bidirectional communication.
SourceDocsify: Can I add versioned documentation?
Not natively. The usual approach is a directory per version with its own sidebar, maintained manually.
