The short version

  • Each has a real cost: Docusaurus customisation past the config file assumes React knowledge, which not every docs team has; Valkey younger project, so its track record is short even though the codebase is not
  • They diverge on capability: Docusaurus covers MDX authoring, Valkey covers Redis-compatible.
  • Prices and features above were last checked on 29 August 2026.

Where each one falls short

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

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

Valkey

  • Younger project, so its track record is short even though the codebase is not
  • Divergence from Redis grows over time, so compatibility is strongest near the fork point and weakens as both evolve
  • Ecosystem tooling and documentation still frequently assume Redis, leaving translation work

Answered from the vendors’ own pages

Docusaurus: 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.

Valkey: Is Valkey free?

Yes, BSD-licensed open source under the Linux Foundation.

Docusaurus: 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.

Valkey: Why does Valkey exist?

Redis changed its licence away from BSD in 2024. Valkey is the community fork continuing under permissive terms, backed by AWS, Google Cloud and Oracle among others.

Docusaurus: 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.

Valkey: Can I switch from Redis to Valkey?

At the fork point it is drop-in compatible with existing clients and data. The further both projects move from that point, the more you should verify the specific features you use.

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.
