The short version
- Each has a real cost: HTMX best suited for server-rendered architectures, not pure client-side SPAs; Docusaurus customisation past the config file assumes React knowledge, which not every docs team has
- They diverge on capability: HTMX covers AJAX requests, Docusaurus covers MDX authoring.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
Docusaurus
- Customisation past the config file assumes React knowledge, which not every docs team has
- Build times grow noticeably on very large sites, particularly with many versions and locales
- Major version upgrades have required real migration work rather than a dependency bump
- It generates a static site, so anything dynamic — gated content, per-user docs — needs a separate solution

Answered from the vendors’ own pages
HTMX: How big is the HTMX JavaScript library?
HTMX is only 16 kilobytes minified and gzipped with zero external dependencies.
SourceDocusaurus: Is Docusaurus free?
Yes. Docusaurus is open source from Meta with no licence fee. You pay only for hosting, and static output can be served from free tiers on Netlify, Vercel or 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.
SourceDocusaurus: What is Docusaurus built with?
React and MDX. Pages are authored in MDX — Markdown that can embed React components — and the theme layer is React, so layouts are extended with components.
HTMX: Does HTMX support real-time features like WebSockets?
Yes, HTMX includes support for WebSockets and server-sent events for real-time bidirectional communication.
SourceDocusaurus: Does Docusaurus support multiple documentation versions?
Yes. Versioning is built in, so documentation for several released product versions can be maintained side by side, which is a main reason projects choose it.
Docusaurus: Does Docusaurus include search?
It integrates with Algolia DocSearch rather than shipping its own search index. Open-source projects can typically use Algolia’s free DocSearch programme.
